Multizone Kubernetes and VPC Load Balancer Setup

,

You can expose your app to the public by setting up a Kubernetes LoadBalancer service in your IBM Cloud Kubernetes Service cluster. When you expose your app, a Load Balancer for VPC that routes requests to your app is automatically created for you in your VPC outside of your cluster.

In this post, you will provision an IBM Cloud Kubernetes Service cluster spanning two private subnets (each subnet in a different zone), deploy an application using a container image stored in an IBM Cloud Container Registry and expose the app via a VPC load balancer deployed to a public subnet in a different zone. Sound complex? Don’t worry, you will provision and deploy the app using Terraform scripts.

Automated Pen Testing With Zed Attack Proxy

,

In this post, you will learn how to execute penetration tests with OWASP Zed Attack Proxy (ZAP). ZAP is a free web app scanner which can be used for security testing purposes.

1. Introduction

When you are developing an application, security must be addressed. It cannot be ignored anymore nowadays. Security must be taken into account starting from initial development and not thinking about it when you want to deploy to production for the first time. Often you will notice that adding security to your application at a later stage in development, will take a lot of time. It is better to take security into account from the beginning, this will save you from some painful headaches. You probably have some security experts inside of your company, so let them participate from the start when a new application needs to be developed. Nevertheless, you will also need to verify whether your developed application is secure. Penetration tests can help you with that. OWASP Zed Attack Proxy (ZAP) is a tool which can help you execute penetration tests for your application. In this post, you will learn how to setup ZAP and execute tests with the desktop client of ZAP. You will also need a preferably vulnerable application. For this purposes, Webgoat of OWASP will be used. In case you do not know what Webgoat is, you can read a previous post first. It might be a little bit outdated because Webgoat has been improved since then, but it will give you a good impression of what Webgoat is. It is advised to disconnect from the internet when using Webgoat because it may expose your machine to attacks.

Execute Spark Applications on Databricks Using the REST API

,

Introduction

While many of us are habituated to executing Spark applications using the ‘spark-submit’ command, with the popularity of Databricks, this seemingly easy activity is getting relegated to the background. Databricks has made it very easy to provision Spark-enabled VMs on the two most popular cloud platforms, namely AWS and Azure. A couple of weeks ago, Databricks announced their availability on GCP as well. The beauty of the Databricks platform is that they have made it very easy to become a part of their platform. While Spark application development will continue to have its challenges – depending on the problem being addressed – the Databricks platform has taken out the pain of having to establish and manage your own Spark cluster.

Using Databricks

Once registered on the platform, the Databricks platform allows us to define a cluster of one or more VMs, with configurable RAM and executor specifications. We can also define a cluster that can launch a minimum number of VMs at startup and then scale to a maximum number of VMs as required. After defining the cluster, we have to define jobs and notebooks. Notebooks contain the actual code executed on the cluster. We need to assign notebooks to jobs as the Databricks cluster executes jobs (and not Notebooks). Databricks also allows us to setup the cluster such that it can download additional JARs and/or Python packages during cluster startup. We can also upload and install our own packages (I used a Python wheel).

10 Best Alternatives to Google Analytics in 2021

,

When you think of installing analytics, you probably reach for Google Analytics. And you wouldn’t be alone. The platform’s tight integration with SEO and the implication that using Google products is beneficial to ranking means that Google Analytics is the most commonly installed analytics solution globally.

Google Analytics isn’t a bad choice: it’s free, it’s fairly comprehensive, and it does indeed tie most SEO efforts up with a nice bow.

But Google Analytics is also slow, extremely bad for privacy — both yours and your users’ — and for many people, it’s too unwieldy, having grown organically over the years into a relatively complex UI.

Some alternatives are fast, privacy-friendly, and geared towards different specialisms. Today we’re rounding up the best…

1. Heap

Heap is an event-based analytics platform. That means you can tell not just how many people visited your site but what actions they took when they were there. This isn’t a unique proposition, but Heap is one of the best implementations.

Heap offers an auto-track tool, which is ideal for new installations because you can get up and running immediately and fine-tune the details later. That makes it great for startups, although it’s also the choice of major corporations like Microsoft.

Heap’s free plan includes 60k sessions per year and 12 months of data history, but when you outgrow that, the business plans start at $12,000/year.

2 ChartMogul

ChartMogul is geared towards SaaS that offer subscription plans, staking a claim as the world’s first subscription data platform.

Services like Buffer and Webflow use ChartMogul to monitor their revenue and analyze the ROI of changes to their features, design, and user experience.

Ideally suited for startups, ChartMogul pricing is based on monthly recurring revenue; it has a free plan for up to $10,000 MMR; after that, pricing starts at $100/month.

3. Fathom

Fathom is an awesome, privacy-first analytics solution. It offers a simple dashboard and is ideal for anyone looking for simple analytics information to verify business decisions.

Fathom is ideally suited to freelancers, or entrepreneurs with multiple projects, as it allows you to run multiple domains from a single account. Fathom is entirely cookieless, meaning you can ditch that annoying cookie notice. It’s GDPR, ePrivacy, PECR, CCPA, and COPPA compliant.

There’s a seven-day free trial; after that, Fathom starts at $14/month.

4. FullStory

FullStory is designed to help you develop engaging online products with an emphasis on user experience.

FullStory is a set of tools, making it ideal for large in-house teams or in-house teams working with outside agencies or freelancers. It pitches itself as a single source of truth from which everyone from the marketing department to the database engineers can draw their insights, helping digital teams rapidly iterate by keeping everyone in the same loop.

FullStory uses AI to track and interpret unexpected events, from rage clicks to traffic spikes, and breaks those events down to a dollar-cost, so you can instantly see where your interventions will have the most impact.

There’s a free plan for up to 1k sessions per month; once you outgrow that, you need to talk to the sales team for a quote.

5. Amplitude

Amplitude has one of the most user-friendly dashboards on this list, with tons of power behind it. For project managers trying to make science-based decisions about future development, it’s a godsend.

The downside with Amplitude is that to make the most of its powerful data connections, you need to pump a lot of data in. For that reason, Amplitude is best suited to sites that already have a substantial volume of traffic — among those customers are Cisco and PayPal.

Amplitude provides a free plan, with its core analytics and up to 10m tracked actions per month. For premium plans, you have to contact their sales team for a quote.

6. Mixpanel

Mixpanel is a little bit more than an analytics program, aiming to be a whole suite of web tools it has ventured into split testing and notifications.

Mixpanel is laser-focused on maximizing your sales funnel. One look at the dashboard, and you can see that Mixpanel, while very well designed, has too many features to present them simply; Mixpanel is ideally suited to agencies and in-house development teams with time to invest — you probably want to keep the CEO away from this one.

Mixpanel has a generous free plan for up to 100k monthly users, with its business plans starting at $25/month.

7. Mode

Mode is a serious enterprise-level solution for product intelligence and decision making.

Ideally suited to in-house teams, Mode allows you to monitor financial flow and output the results in investor-friendly reports. You can monitor your entire tech stack and, of course, understand how users are interacting with your product. Wondering who handles the analytics for Shopify? That would be Mode.

Mode has a free plan aimed at individuals, but this tool’s scope is really beyond freelancers, and the free plan’s only likely to appeal to high-price consultants and tech trouble-shooters. For the full business plan, you need to contact Mode’s sales team for a quote.

8. Microanalytics

Microanalytics is a relatively new analytics program with a lightweight, privacy-focused approach.

Microanalytics provides a simple dashboard with acquisitions, user location, technology, and the all-important event tracking to monitor user behavior. Microanalytics is compliant with the web’s most stringent privacy laws, including GDPR, PECR, and CCPA. The tracking code is just 1kb in size, meaning that you’ll hardly notice its footprint in your stats.

Microanalytics is free for up to 10k pageviews/month; after that, the monthly plan starts at $9.

9. GoSquared

GoSquared is another suite of tools, this time aimed at SaaS. Its primary product is its analytics, but it also includes live chat, marketing tools, and a team inbox.

If you’re tired of comparing multiple tools to help make the most of your startup, GoSquared kills several birds with one stone. Perhaps most importantly, if you’re beginning to build a team and don’t have any engineers onboard yet, GoSquared has an award-winning support team and an idiot-proof setup process.

GoSquared has a free plan that’s fine for evaluating the suite and integrating data from day one. As you begin to grow, paid plans start at $40/month.

10. Segment

Segment is a little different from the other analytics tools on this list; Segment is a layer that sits between your site and your analytics. It integrates with many of the tools on this list.

There are several benefits to this approach. The main one is that different teams within your enterprise can access analytics data in a form that suits them — designers can access complex data, and management can stick to revenue flow. It also means that you can switch analytics programs with a single setting in Segment and even migrate historical data into new apps. If you’re an enterprise that wants to future-proof its customer intelligence gathering, Segment is worth considering.

Segment is trusted by some of the web’s best-known names, from IBM to Levis, and…ahem…Google.

Segment is free for up to 1k visitors per month, and after that, the team plan starts at $120/month.

6 Best Ecommerce Solutions for 2021

,

It’s never been easier to set up an ecommerce store and start selling. There are a dizzying array of ecommerce solutions available in 2021, and most are feature-rich and competitively priced.

Ecommerce sites are notoriously difficult to migrate from platform to platform, so more often than not, you’ll be committed to your chosen solution for years. The key when choosing an ecommerce solution to maximize your return on investment, is to consider not just what your business needs today but what it will need tomorrow.

There are two basic approaches to ecommerce. The first is a dedicated platform that handles everything. The second is a plugin that adds ecommerce features to an existing CMS. Both approaches have benefits and drawbacks.

1. Shopify: Best for Almost Everyone

Shopify is a well-known, well-liked, and reliable dedicated ecommerce platform. As a system for getting a business off the ground and selling fast, it is peerless.

Shopify jealously guards developer access, with templates and plugins pre-vetted. Unlike some marketplaces, you can be confident that there are no hidden surprises in your shiny new store.

And because Shopify has passed the point of market saturation, it’s worthwhile for big players to provide their own plugins; credit services like Klarna and shipping companies like netParcel can be integrated with a few clicks.

The admin panel is a touch complex, as Shopify is designed to allow a single account to be linked to multiple stores. But once you’re set up and familiar with where to find everything, it’s a slick, streamlined business management system.

Whenever a client says, “we want to start selling online.” My first thought is, “Shopify.” And for 90% of clients, it’s the right choice.

And that’s where this roundup should end…except there’s still that 10% because Shopify isn’t perfect.

For a start, an all-in-one platform doesn’t suit everyone. If you already have a website you’re happy with, you’ll either need to migrate or lease a dedicated domain for your store.

Shopify’s platform is very secure, which inspires confidence in buyers, but the price of that security is a lack of flexibility in the design.

Then there’s the infamous variant limit. Shopify allows 100 variants on a product. Almost every client runs into that wall at some point. Let’s say you’re selling a T-shirt: male and female cuts are two variants; now add long or short sleeves, that’s four variants; now add seven sizes from XXS to XXL, that’s 28 variants; if you have more than three color options, you’ve passed the 100 variant limit. There are plugins that will allow you to side-step this issue, but they’re a messy hack that hampers UX for both customer and business.

Shopify should certainly be on every new store owner’s shortlist, but there are other options.

2. WooCommerce: Best for WordPress Users

If you’re one of the millions of businesses with a pre-existing site built on WordPress, then adapting it with a plugin is the fastest way to get up and running with ecommerce.

WooCommerce is regularly recommended as “Best for WordPress Users,” which is a back-handed compliment that belies the fact that WooCommerce reportedly powers 30% of all ecommerce stores. If running with the crowd appeals to you — and if you’re using WordPress, it presumably does — then you’re in the right place.

WordPress has a gargantuan plugin range. As such, there are other plugins that will allow you to sell through a WordPress site. The principle benefit of WooCommerce is that as the largest provider, most other plugins and themes are thoroughly tested with it for compatibility issues; most professional WordPress add-ons will tell you if they’re compatible with WooCommerce. If your business is benefitting from leveraging WordPress’ unrivaled ecosystem, it can continue to do so with WooCommerce.

The downside to WooCommerce is that you’re working in the same dashboard as the CMS that runs your content. That can quickly become unmanageable.

WooCommerce also struggles as inventories grow — every product added will slow things a little — it’s ideally suited to small stores selling a few items for supplementary income.

3. BigCommerce: Best for Growth

BigCommerce is an ecommerce platform similar to Shopify, but whereas Shopify is geared towards newer stores, BigCommerce caters to established businesses with larger turnovers.

The same pros and cons of a dedicated ecommerce solution that applied to Shopify also apply to BigCommerce. One of the considerable downsides is that you have less control over your front-end code. This means that you’re swapping short-term convenience for long-term performance. Templates, themes, and plugins — regardless of the platform they’re tied to — typically take 18 months to catch up with best practices, leaving you trailing behind competitors.

BigCommerce addresses this shortcoming with something Shopify does not: a headless option. A headless ecommerce platform is effectively a dedicated API for your own store.

Enabling a headless approach means that BigCommerce can be integrated anywhere, on any technology stack you prefer. And yes, that includes WordPress. What’s more, being headless means you can easily migrate your frontend without rebuilding your backend.

BigCommerce also provides BigCommerce Essentials, which is aimed at entry-level stores. It’s a good way to get your feet wet, but it’s not BigCommerce’s real strength.

If you have the anticipated turnover to justify BigCommerce, it’s a flexible and robust choice that you won’t have to reconsider for years.

4. Magento: Best for Burning Budgets

If you have a development team at your disposal and a healthy budget to throw at your new store, then Magento could be the option for you.

You can do almost anything with a Magento store; it excels at custom solutions.

Magento’s main offering is its enterprise-level solution. You’ll have to approach a sales rep for a quote — yep, if you have to ask the price, you probably can’t afford it. Magento has the track-record and the client list to appeal to boards of directors for whom a 15-strong development team is a footnote in their budget.

That’s not to say that a Magento store has to be expensive; Magento even offers a free open source option. But if you’re not heavily investing in a custom solution, you’re not leveraging the platform’s key strengths.

5. Craft Commerce: Best for Custom Solutions

If you’re in the market for a custom solution, and you don’t have the budget for something like Magento, then Craft Commerce is ideally positioned.

Like WooCommerce for WordPress, Craft Commerce is a plugin for Craft CMS that transforms it into an ecommerce store.

Unlike WordPress, Craft CMS doesn’t have a theme feature. Every Craft Commerce store is custom built using a simple templating language called Twig. The main benefit of the approach is that bespoke solutions are fast and relatively cheap to produce, with none of the code bloat of platforms or WordPress.

Because your site is custom coded, you have complete control over your frontend, allowing you to iterate UX and SEO.

You will need a Craft developer to set up Craft Commerce because the learning curve is steeper than a CMS like WordPress. However, once you’re setup, Craft sites are among the simplest to own and manage.

6. Stripe: Best for Outliers

Ecommerce solutions market themselves on different strengths, but the nature of design patterns means they almost all follow a similar customer journey: search for an item, add the item to a cart, review the cart, checkout. Like any business, they want to maximize their market share, which means delivering a solution that caters to the most common business models.

Occasionally a project happens along that doesn’t fit that business model. Perhaps you’re selling a product that’s uniquely priced for each customer. Perhaps you’re selling by auction. Perhaps you don’t want to bill the customer until a certain point in the future.

Whatever your reason, the greatest customization level — breaking out of the standard ecommerce journey — can be managed with direct integration with Stripe.

Stripe is a powerful payment processor that handles the actual financial transaction for numerous ecommerce solutions. Developers love Stripe; its API is excellent, it’s documentation is a joy, it’s a powerful system rendered usable by relentless iteration.

However, this approach is not for the faint-hearted. This is a completely custom build. Nothing is provided except for the financial transaction itself. Every aspect of your site will need to be built from scratch, which means hefty development costs before seeing any return on investment.

The Best eCommerce Solution in 2021

The best ecommerce solution is defined by three factors: the size of your store, the anticipated growth, and the degree of custom design and features you want or need.

Shopify is the choice of most successful small stores because you can be selling inside a day. For businesses with an existing presence and a smaller turnover, those on WordPress will be happy with WooCommerce. For larger stores planning long-term growth, BigCommerce’s headless option is ideal. Craft Commerce is a solid performer that marries low costs with flexibility for businesses that need a custom approach.

6 Tools for Rapid Cross-Device Website Testing

,

When creating a website, it’s vital to remember that not only does it need to work and look great on the device you are creating it on, but on all the other devices, it might be used on too.

Mobile and tablet optimization is important not only for the user journey but from an SEO point of view too, and badly created mobile sites just don’t cut it anymore.

With more and more devices entering the market, you need to check any website you create is compatible across the board. One bad experience and users are likely to leave and not come back again, which can be catastrophic for a business, particularly if it is just starting out.

It’s vital to check how a site looks and behaves when browsed differently from how you would use it. A common mistake is to assume users only browse websites on mobile devices in portrait mode; they don’t; landscape browsing is common, especially if the user is used to watching video.

Here are some of our top tools for testing websites on devices without the need for an entire device library:

1. Multi-Screen Test

WhatIsMyScreenResolution offers a great little tool to test how your site will look on different devices easily, and it costs absolutely nothing. You put the URL and choose between desktop, mobile, tablet, and television and then the orientation. Each device can also be broken down into different sizes and resolutions (or you can enter your own), making it easier than ever to test what a site will look like on different devices.

2. Responsinator

Responsinator is another great tool to test how a site looks on other devices without dipping into your wallet. Put your URL in the top bar, and it will instantly show you what it looks like on generic devices. This is a great, easy to use tool, and you can click through any links on your site to check the usability of multiple pages. This site is free, but if you want to “create your own” template, you need to sign up.

3. Google Dev Tools

Google Dev Tools is one of the most commonly used free tools. Add it to Chrome, and you can see how your site looks in a multitude of different screen sizes and resolutions. You can simulate touch inputs, device orientation, and geolocation to test how they work. It’s great to easily spot problems using their remote debugging tool to view, change, debug and profile a page’s code directly from your laptop or computer while viewing it on your mobile device.

4. Browser Stack

Browser Stack allows you to test your site on over 2,000 real devices and browsers, enabling you to see in real-time how your site looks. It is no hassle to set up, and it can be seamlessly integrated into your setup. As it tests on real browsers on real machines, you know the results are more reliable and accurate. It also enables you to debug in real-time using their pre-installed developer tools for ease of editing. The tests are all run securely on tamper-proof physical devices and are wiped clean of all data after each session, so you don’t need to worry about security being compromised.

5. TestComplete Mobile

TestComplete Mobile allows you to create and run UI tests across real mobile devices, virtual machines, and emulators. You can test both mobile device layouts and apps with script-free record and replay actions. This can help you to edit and fix any potential issues that may arise during the tests. Due to them being conducted on real devices, you know it is less likely to have errors in the system than a simulated device. This is free for 30 days then can get pricier, so make sure you take advantage of the trial and try the service before committing to it.

6. Sizzy

Sizzy is a great tool for checking sites, and it has a host of features to assist you. You can rotate the screen between portrait and landscape, filter by OS and device type, switch themes, and take screenshots. These little things mean it’s a super easy to use and convenient tool. It claims to simulate each device’s viewport and user agent, meaning the results are the same as what you would actually see on that phone/ tablet, etc. It can’t simulate different browser rendering engines however, so there’s a chance there might be some minor differences compared to the actual thing. Sizzy offers a free trial or has different price packages starting at $5 per month.

Display the Latest News on Your Site With Mediastack

,

What an extraordinary year 2020 has been for the news! From the ongoing coronavirus crisis, to a turbulent US election, to the unrelenting march of Bitcoin, this year like no other we’ve been glued to our phones micro-analyzing every tidbit of news.

Which makes this the perfect time for mediastack, an awesome REST API that allows you to embed a customizable news feed, sourced from the world’s top news agencies, and updated by the minute, right on your site.

Integrating Global News with Your Site

News is the beating pulse of so many global industries. From political decisions that affect stock prices, to natural disasters that interrupt goods and services, to the whims of celebrities who overnight transform brands from unknown to must-have.

Whether you’re building a site for a non-profit in Louisiana that cares deeply about both Washington politics, and hurricanes in the Caribbean; or you’re building an app for a golf course in Halkidiki that’s focused on both local news, and golf around the world; delivering real-time news content to those users elevates UX.

Tightly integrating the news with your site makes it a hub for users hungry for that very news. The only limit is your creativity.

Display Up-to-Date News on Your Site

When news breaks around the world the top networks scramble to catch up; they simply can’t maintain correspondents in every town and city in the world, and so they rely on affiliates. mediastack pulls in news from over 7,500 different sources in over 50 countries worldwide, giving you access to exactly the same affiliates frequently used by big news organizations like CNN, MSNBC, BBC, or ABC.

When it’s one of the big players in news that breaks a story first, mediastack still has you covered because as will as covering smaller, lesser-known sources mediastack delivers real-time news from CBS, Sky News, The Guardian, Al Jazeera, USA Today, and a host of trusted names across the industry.

If your site targets users that are only interested in certain types of story — like sports, or Hollywood celebrities — then you can even pull in stories from ESPN, TMZ, or Fox News.

Get Started Quickly with mediastack

Getting started with mediastack couldn’t be simpler, and there’s a free plan that’s more than enough to prototype your project.

Full documentation is provided with code examples for PHP, Python, jQuery, Go, and Ruby. To start integrating all you need to do is register for a free access key.

Once you have your free access key, you connect to the API, then customize the results you receive with simple parameters. You can specify the types of news, the precise sources (including omitting sources), languages, countries, and most importantly your keywords.

For example here’s how you’d request science news from CNN, but not TMZ:

https://api.mediastack.com/v1/news
?access_key=[ INSERT YOUR ACCESS KEY HERE ]
&categories=science
&sources=cnn,-tmz

Let’s say you want to display Spanish language crypto news on your site, it couldn’t be easier:

https://api.mediastack.com/v1/news
?access_key=[ INSERT YOUR ACCESS KEY HERE ]
&categories=business,technology
&languages=es
&search=crypto,bitcoin,btc,xrp,ripple,etherium,altcoin

The API sends back simple JSON data that’s easy to run through. Each news item includes the author, title, description, url, source, image, category, language, country, and a published_at timestamp that records when the story was posted.

Once the feed is setup, sit back and relax. It’s all automated from now on.

The Best Source of News for Your Website

mediastack is delivered by apilayer, quite rightly one of the most trusted names in APIs, and is capable of handling millions of requests simultaneously.

Fast, updated by the minute, highly customizable, reliable, and sourced from the biggest names in the news industry, mediastack is an amazing API.

There’s a free-forever plan that allows you to use the API without charge, for up to 500 API calls per month, that’s perfect for trying it out.

For commercial use, plans start at just $19.99/month, and can handle up to 250,000 calls per month. Commercial plans also include HTTPS encryption, live news delivery, access to historical data, and — should you ever need it — technical support.

Head over to mediastack today, to prepare your site for whatever events 2021 throws at us.

AccessiBe Review 2020: Solving Web Accessibility with AI and Scalability

Web accessibility is important for two reasons:

  1. Being ADA & WCAG compliant is required by law (we’ll explain this further) so if your website isn’t compliant, you can get sued.
  2. It allows people with disabilities to browse your website, which increases your potential audience and it is the decent thing to do.

In this accessiBe review, we’ll cover:

How Does accessiBe Work

accessiBe is an automated solution that combines two applications to achieve full compliance.

Foreground application: the accessibility interface. This is the accessibility menu that allows users with disabilities to adjust the various UI and design elements on your website so it meets their unique needs.

Background application: proprietary AI technology that’s responsible for the ‘heavy lifting’, screen-reader, and keyboard navigation optimization.

The combination of these two applications is unique for accessiBe for a few reasons. While most available accessibility solutions offer just one of the two or rely on manual remediation, accessiBe checks both boxes and does it in a fully automated way.

Additionally, and most importantly, accessiBe continuously scans your website, every 24 hours, identifying and fixing new accessibility issues as they arise. Websites are dynamic – meaning, keep updating constantly with new content, pages, images and so on; being ADA and WCAG compliant is an ongoing concern, not a one-time fix.

How to Install and Setup accessiBe

You install accessiBe by inserting a single line of code on your website.

From your end, that’s all it takes.

The first thing that happens is that the accessibility interface appears on your website. The menu is available via the accessibility icon (that also appears automatically.)

Source: accessiBe website

Next, the AI application scans and analyzes your website for accessibility issues and compatibility with screen-readers and keyboard navigation requirements and fixes them. This automated process takes 48 hours.

Once the initial 48 hours have elapsed, your website is compliant.

From here on, accessiBe automatically scans your website every 24 hours to identify and fix new accessibility issues as they arise due to website updates.

Why Ongoing Compliance is Important

We’ve mentioned this already, but it’s important to stress this point.

Whether you have an e-commerce website or a company website, you keep updating and changing your website; new items go up for sale, new videos and content pieces are added. Every addition or removal from your website has the potential of creating accessibility gaps (like missing alt text for images.)

By continuously scanning and fixing your website, accessiBe ensures that you stay compliant. An accessibility audit remediates your website for the specific point in time the audit took place. Meaning, you’ll need to audit your website periodically to remain compliant, which is a costly affair. With accessiBe you don’t need to worry about this.

accessiBe Front End Features – The Accessibility Interface

The accessiBe accessibility interface (the menu that is available for users) is installed automatically on your website once you insert the line of code. Let’s look at the various features that are available for people with disabilities.

Accessibility Profiles Explained

First, it allows you to choose from a pre-defined set of profiles optimized for various disability needs:

When one of the profiles is selected, the required adjustments are instantly applied to your entire website.

For example, The ADHD Friendly Profile creates a reading mark that follows your mouse movements that diminish distractions and allows better focus:

The Cognitive Disability Profile frames all the elements in bounding boxes and adds an ‘reading cursor’ that acts as your mouse to allow enhanced orientation:

Each of the predefined profiles includes a suite of features that target the unique accessibility needs of the disability; the Epilepsy Safe Profile prevents videos from playing automatically, dims all the colors on your website and eliminates flashing and blinking animations; the Visually Impaired Profile enhances all your website’s visuals, enlarges all fonts to allow most visual impairments conditions (degrading eyesight, tunnel vision, cataract, glaucoma and more) to be able to browse your website with ease.

The last two profiles, Blind Users and Keyboard Navigation, work in unison. They allow blind and motor-impaired individuals to browse and use your website as they are used to, through screen-readers and keyboard functionality, respectively.

Two things need to be mentioned here:

  1. Blind individuals have screen-readers installed on their computers in the OS-level, meaning, on the hard drive of the computer. They use them to navigate the internet by having the software read for them every text that appears on the screen. As can be seen in the screenshot above, the Blind User profile is ‘launched’ automatically once accessiBe detects that the user is using a screen-reader. This is a crucial functionality since obviously blind users aren’t able to locate the accessibility icon.
  2. The same goes for individuals that are using the keyboard instead of a mouse to navigate the web, both the motor-impaired and the blind. accessiBe detects and automatically enables keyboard navigation on your website.

On top of the predefined accessibility profiles, accessiBe’s interface allows for further adjustments that can be controlled specifically to allow a personalized browsing experience according to the user’s needs. Let’s look at these adjustments.

Accessibility Content Adjustments Explained

The content adjustments allow you to control every aspect of the written content on your website. The menu looks like this:

Each of these elements allows for granular control of the way content, or text, is presented. From altering the entire website’s text to a readable, sans-serif font that is easier to follow, to highlighting titles and links, to adjusting font size, the spacing between lines and letters and using a text magnifier that follows your cursor on the screen.

Here’s how it looks with Highlight Titles and Highlight Links turned on:

You can see all the links are highlighted with an orange bounding box while all titles are highlighted with a blue bounding box.

Accessibility Color Adjustments Explained

The color adjustments allows users to control every aspect of the color scheme on the website:

From adjusting contrast and saturation, to switching the entire website to a monochrome color scheme, to adjusting textual elements and background colors. Let’s look at a few examples.

Here’s a side-by-side of default appearance and the Dark Contrast adjustment turned on:

And here’s how it looks with the Monochrome adjustment turned on:

Accessibility Orientation Adjustments Explained

The orientation adjustments allow full control of ‘distractions’ that make it hard for individuals with epilepsy, ADHD, and cognitive disability to browse the web:

As such, the orientation adjustments allow users to mute sound, hide images, stop animations and additional ‘focus’ features such as an enlarged cursor and reading assistance that highlights the text being read.

Here’s how the Remove Images adjustment works:

accessiBe Back End Features

Unlike ‘accessibility plugins’ (more on that later) accessiBe provides a comprehensive back end treatment to your website – automated, AI-powered analysis of compatibility with accessibility requirements and fixing of the elements that need adjustment.

It should be noted that 70% of the WCAG compliance requirements deal with screen-reader and keyboard navigation compatibility and all these requirements are not answered by installing an accessibility interface widget that merely makes UI and design adjustments.

For example, an accessibility widget will enable you to enlarge the font on your website, to adjust the saturation or to highlight links, but it won’t enable a blind individual to differentiate between a shopping cart icon and a checkout icon, nor will it enable a motor impaired individual to easily navigate a menu.

This is a crucial consideration to make when choosing a web accessibility solution. Being WCAG compliant is a YES / NO situation. Your website is either compliant or it’s not, there is no middle ground here.

accessiBe’s back end features come to solve and answer all these compatibility issues that enable full screen-reader and keyboard navigation functionalities.

Screen Reader Compatibility Explained

Screen Reader is a software for blind individuals to use computers and browse the web. As the name suggests, the software reads aloud what is seen on the screen for blind individuals.

The screen reader software is installed on the computer. But in order for it to work with websites, the website needs to be compatible with the software. To achieve compatibility with screen reader software, WCAG requires that a website should adhere to a set of attributes called Accessible Rich Internet Applications (ARIA) that are installed within the website’s code, allowing it to ‘communicate’ with the screen reader.

Let’s take social icons as an example. We are all familiar with those icons – Facebook, Twitter, Instagram – they are instantly recognizable for us visually. A screen reader software doesn’t actually ‘see’ elements on the screen, rather it scans the website’s code to understand what appears on the screen. As such, a Facebook icon code simply says ‘link’ and has the URL that directs the user when clicking the link.

So with a website that isn’t compatible with a screen reader, that doesn’t have ARIA tags implemented, the screen reader will read to the blind person “link” for the Facebook icon; not very helpful, is it?

When ARIA tags are implemented, additional information is added to the Facebook icon – and any other visual link on the website – that describes what is the link. So the screen reader will read to the blind person “Facebook link”.

It’s not difficult to imagine the scope and effort of the work needed in order to implement ARIA tags on your entire website.

Keyboard Navigation Compatibility Explained

Keyboard navigation means that motor-impaired individuals are using their computers only through their keyboard, rather than a mouse. Scrolling, clicking links and menu buttons, opening and closing tabs – everything is done using designated keys.

There are many issues relating to keyboard navigation as today’s websites are highly complex, layered with content elements, and react dynamically to user behavior. Any element of the website must be compatible to allow full keyboard navigation.

Let’s look at a popup as an example.

Popups can be triggered for a variety of reasons. For mouse users, it is a simple occurrence; you can bring the cursor to the area of the popup, click on one of the fields to input details or click the X to close the popup.

But how do you handle the popup using only the keyboard? How do you differentiate between ‘regular’ functionalities of the website and that of the popup? How do you ‘shift the focus’ of the keystrokes to a layered element? You need to allow unique keystrokes to operate the popup, keystrokes that are activated only when a popup appears.

It’s one example of the many challenges making your website compatible with keyboard navigation. The list of WCAG requirements for compatibility with keyboard navigation is a long one, and understandably so as it needs to enable motor-impaired individuals to navigate your website with the same ease as the rest of us using a mouse.

How accessiBe’s Background Processing Achieves Screen Reader and Keyboard Navigation Compatibility

Without getting too technical, what accessiBe does is scan the entire code of your website and adds keyboard functionalities and ARIA tags to various elements on your website directly. It won’t interfere with your site’s code, but rather add an additional ‘layer’.

accessiBe’s AI ‘learned’ all of ARIA’s tags and keyboard functionalities required by WCAG and when scanning your website’s code implements all the required adjustments to achieve full compliance.

How accessiBe Makes Menus Accessible

Menus are a good example for understanding what the accessiBe background processing does and the benefits it provides.

We recognize menus on websites instantly, because we saw thousands and thousands of them. We know how they look, we know what their functionality is, and we know where to hover and click in order to reach the various pages of the website.

But if you remember, we said that screen readers don’t ‘look’ at the screen, but rather scan the site’s code to understand structure, identify links and read them aloud with all the text that appears on the page.

So menus are coded as a list structure, because in a way they are. A screen reader will announce a menu as a list, which might be confusing for a blind user. Additionally, many menus have drop-down sub-menus, accessible via a hover or by clicking a little triangle. Without proper ARIA tagging, a screen reader will miss the sub-menu.

What accessiBe does is adding readable tags for every element in the menu so a screen reader will recognize and announce each element properly. The ‘list’ code structure will get a “menu” tag, and the sub-menu will get a tag for ‘sub-menu’, thus allowing the blind individual to utilize the full functionality of the website.

Additionally, accessiBe alternates the tags on-the-fly while the site is being browsed. Once a sub-menu has been opened, a tag that says “sub-menu open” will be added to indicate to the screen reader what has happened, and will be changed with the tag “sub-menu close” once the sub-menu has been closed.

Image Recognition

One of the key elements of accessibility compliance with screen readers is to provide accurate alternative descriptions for images, known as alt text.

accessiBe utilizes various image, object and character recognition technologies (OCR and Iris) to provide highly descriptive and accurate depictions of images displayed on the website. Without adding screen-reader compatible alt tags to images a blind individual would simply not be aware of the existence of images, and miss out on the information usually displayed on images.

Let’s look at the following banner images from an e-commerce website:

As you can see, valuable information is communicated via the images – sales and discounts – the kind of information any shopper would want to know.

This is the descriptive text that accessiBe’s AI assigned to these images, completely automated with no human intervention (from left to right):

  • Image contains: shopping,  shorts, woman, ashion; image text: extra 50% off shorts
  • Image contains: shopping, red top, woman, jeans, fashion; image text: 50% off bottoms
  • Image contains: shopping, blue jumpsuit, woman, fashion, bed, ; image text: 50% off jumpsuits & rompers
  • Image contains: shopping, shoes, ocean, woman, fashion; image text: 50% off shoes

Again, doing this kind of work for the hundreds to thousands of images that are displayed on every e-commerce website requires a lot of time and effort. accessiBe achieves this in a completely automated way, and every image added to your website instantly gets its alt text.

Comparison of accessiBe with Accessibility Plugins

There are many web accessibility plugins out there. They offer a ‘quick fix’ for ADA and WCAG compliance – add an accessibility menu and you’re done.

As tempting as it may sound, the distinction between an accessibility menu and being fully compliant must be made.

As we’ve mentioned earlier, there are two parallel tasks that need to handle in order to achieve ADA and WCAG compliance:

  • Front end – UI and design adjustments, achieved by the Accessibility Interface (the visible menu for content, font, color and orientation adjustments)
  • Back end – screen-reader and keyboard navigation compatibility, achieved by implementing ARIA tags and further code adjustments

Reminder: 70% of accessibility compliance requirements deal with back end adjustments, meaning, screen-readers, and keyboard navigation compatibility.

Accessibility plugins, whether free or paid, only answer the front-end requirements. Meaning, after installing an accessibility plugin, you are just 30% compliant. Since accessibility compliance is not a scale (you don’t ‘get points’ for making it halfway through) you’ll need to turn to an additional provider to do the back end work.

accessiBe, on the other hand, provides a full accessibility compliance solution, covering both UI and design requirements through the accessibility interface AND screen-reader and keyboard navigation compatibility requirements through it’s automated AI technology that analyzes and makes adjustments in the code-level of the website.

Benefits of Using accessiBe Over Accessibility Plugins

  • Achieving complete accessibility compliance
  • Dealing with a single provider, rather than two or more
  • Cost-efficiency (manual audit and remediation service are expensive)
  • Complete compatibility with screen-readers and keyboard navigation
  • Enabling true accessibility to individuals with disabilities

Comparison of accessiBe with Manual Accessibility Services

Manual accessibility services can help you achieve full accessibility compliance, but it comes with two major disclaimers:

  1. You’ll still need an additional solution for an accessibility interface, which the service companies don’t provide
  2. The compliance achieved is for the point in time the audit and remediation were performed. Let’s explain this point further.

Companies that offer a manual accessibility service assign a team of accessibility experts to do an audit of your website. The result of this audit is a lengthy document detailing all the accessibility faults that your website has. It is a valuable document as it gives you a precise depiction of what needs to be fixed in order to achieve compliance.

From here there are two possible paths:

You can either take the audit results to your development team and have them remediate your website accordingly.

Or, some of the service companies offer a remediation service, meaning, they’ll assign their own engineers to manually make the necessary changes in your website. Needless to say this extra service isn’t given for free.

In both cases, you are looking at a process that takes weeks if not months (depending on the number of pages your website has.)

Additionally, since it is a manual process done by experts, it comes with a hefty price tag.

But most importantly, the audit and remediation hold for the time they were done. Unless you have a 100% static website, meaning, you do not make any changes to your website – never add or remove products, never update content – the ‘effect’ of the audit and remediation fades away with time.

Since the process was manual, any changes you make to your website must be handled manually accessibility-wise. You added a new banner with a link to items on sale, you’ll need to go into the code and add ARIA tags. You added a new image, you’ll need to go into the code and add alt text compatible with screen-readers. And so on.

Some of the manual accessibility service companies offer maintenance services as well. They will periodically audit your website (manually) and provide a remediation document that will need to be implemented (manually) either by your development team or by theirs for an additional cost.

These costs add up. Having your website audited and remediated for compliance on an ongoing basis takes time, effort, and money. But you don’t have a choice. Being ADA and WCAG compliant is an ongoing task, since websites are dynamic and being updated regularly.

accessiBe, on the other hand, offers a 100% automated and ongoing compliance solution. The initial audit and remediation process is carried out – with no human intervention – in 48 hours (compared to weeks or months by a manual provider). Then, your website is scanned every 24 hours to identify and fix accessibility issues using accessiBe AI technology. Meaning, compliance maintenance is constantly carried out ‘in the background’ keeping you ADA & WCAG compliant at all times.

Which brings us to another crucial point regarding manual accessibility services. They make it extremely hard for you to scale up. Every business has a constant aim to grow, but with a manual accessibility service, scalability becomes a pain point. The more you grow the more time, effort and money you need to put in to remain compliant. You want to add another section to your website, you want to launch an additional website? Using a manual accessibility service will hold you back. You’ll need to account for additional time before going live to manually enable accessibility and additional funds. For fast-moving companies, time becomes a serious burden.

Since accessiBe offers an automated and ongoing accessibility solution, scalability is not an issue.

Benefits of Using accessiBe Over Manual Accessibility Services

  • Time-efficient
  • Cost-effective
  • 100% automated
  • Ongoing compliance
  • Infinite scale
  • Single provider for full compliance (front end and back end)

How to Check Your Web Accessibility Compliance Level

Before you get started on your path to being ADA & WCAG compliant it’s important to understand the current state of accessibility your website provides.

Obviously, if you’ve never taken any steps to make your website accessible to individuals with disabilities, there’s no need for this – your website isn’t accessible in any way.

This is actually highly important if you have taken steps to make your website accessible, like for example, installing one of the accessibility plugins. You might be under the impression that by doing so your website is both compliant and accessible to individuals with disabilities.

There’s a simple and quick way to face the accessibility reality.

accessiBe offers a free, automated compliance audit tool available online named aCe. It uses accessiBe AI technology to scan your site, detect accessibility issues and provide quite a detailed report on the various elements that impact your website’s accessibility, and those include:

  • General score
  • Clickables
  • Titles
  • Orientation
  • Menus
  • Graphics
  • Forms
  • Documents
  • Readability
  • Carousels
  • Tables

Each of these elements is given a score and some explanations to the specific issues that need attention within the context of these elements.

In addition to gaining a compliance audit with the remediation steps needed to be taken in order to fix these issues, aCe gives you a very clear idea of where you stand and what needs your attention in order to achieve compliance.

We gave it a try. We ran a website that has installed one of the accessibility plugins (which was recognized, by name, by the aCe audit tool) and the results cement the point that these plugins aren’t comprehensive enough of a solution for true ADA & WCAG compliance.

Here are the results:

As can be expected, the UI and design side got relatively high scores, due to the accessibility plugin installed on the website, but anything that has to do with back end compatibility with screen readers and keyboard navigation got a failing score.

Conclusion

accessiBe is an automated and comprehensive web accessibility solution that achieves ongoing compliance with ADA and WCAG regulations for your website.

It offers a unique combination of front end and back end compatibility, meaning, it provides an end-to-end solution for both user-facing accessibility interface, and compatibility with screen readers and keyboard navigation.

Connecting Sequelize To a PostgreSQL Cluster

,

Prologue

In a previous post, I showed how to automate a PostgreSQL fault-tolerant cluster with Vagrant and Ansible.

This kind of setup makes our database cluster resilient to server failure and keeps the data available with no need for human interaction. But what about the apps using this database? Are they fault-tolerant too?
