In application development, microservices is an architectural style where larger applications are structured as a collection of smaller, independent, yet interconnected services. While this allows for highly maintainable and testable applications (as each service can be maintained independent of the larger application), the problem with this method is the inherent complexity of interactions between microservices. It can be difficult for developers and team members to visualize how these microservices are connected to each other. We have been looking for ways to produce architectural diagrams that illustrate these interactions. We found that GraphViz helped us to solve part of this problem, as it can take the microservices structure of an application in the DOT language and convert it into a PNG format. However, we wanted this process to be even more user-friendly and more automatic, so that the user would not have to manually generate a DOT file of their microservices architecture. 

In-Browser Tool

As we could not find such a tool, we decided to create one ourselves. We decided that the most user-friendly interface would be to create an in-browser tool that allows the user to upload a jar  file containing a packaged service, and to have an image automatically rendered. This article discusses how we went about creating this tool and includes an example of what happens « behind the scenes » of this interface.

Datadog is an exceptional tool for DevOps teams, developers, and SREs. It’s suitable for a broad range of cloud applications of every size. However, despite its powerful capabilities, most businesses aren’t making the most of Datadog. Are you?

  • Can you see how newly launched features are affecting user experience?
  • Can you immediately see the root cause of an issue on your dashboard – without digging around? 
  • Are you managing Jira tickets directly in Datadog?

Datadog’s integrations help make the platform stand out, but using them to make Datadog more powerful can be confusing, as there are over 500 interesting tools to consider.

The introduction of the continuous integration/continuous deployment (CI/CD) process has strengthened the software release mechanism, helping products go to market faster than ever before and allowing application development teams to deliver code changes more frequently and reliably. Regression testing ensures no new mistakes have been introduced to a software application by testing newly modified code as well as any parts of the software that could potentially be affected. The software testing market size is projected to reach $40 billion in 2020 with a 7% growth rate by 2027. Regression testing accounted for more than 8.5% of market share and is expected to rise at an annual pace of over 8% through 2027, as per reports from the Global Market Insights group.

The Importance of Regression Testing

Regression testing is a must for large-sized software development teams following an agile model. When many developers are making multiple commits frequently, regression testing is required to identify any unexpected outcome in overall functionality caused by each commit. The CI/CD setup identifies that and notifies the developers as soon as the failure occurs and makes sure the faulty commit doesn’t get shipped into the deployment.

In the early days of the internet, security was little but an afterthought. Then as hackers started to exploit businesses’ lax security postures, things gradually started to change. At first, nonprofits like the Electronic Frontier Foundation started pushing web users to embrace HTTPS Everywhere. In response, certification authorities began offering free SSL certificate variations to any site admin that wanted one. As a result, at least 79.6% of all active websites now use SSL.

That was only the beginning. In the ensuing years, developers and web application administrators gradually started to harden their apps against all manner of attacks. They rolled out more complex password requirements. They started to add two-factor authentication as a default measure. They even started putting public-facing services behind high-performance web application firewalls.

For developers working with low-resource environments that nevertheless wish to harness the full advantages of Kubernetes, the open-source Red Hat MicroShift project and Shipa (an application-as-code platform you can spin up for free) offer a rather compelling pairing. In this article, I’ll take you through the steps of using MicroShift to set up a lightweight Kubernetes distribution, and then manage the same cluster using the “free forever” version of Shipa Cloud. 

But first, why MicroShift? A research project started by Red Hat, MicroShift is built for running Kubernetes clusters in environments with tight resource constraints, such as edge and IoT devices. It’s a memory-optimized lightweight flavor of OpenShift/Kubernetes, and currently supports Fedora, RHEL, and CentOS Linux distributions. Shipa fits in here by helping solve some of the usual problems faced by developers and platform operators. It lets developers focus on what they’re good at and want to do (building applications) and reduces the time platform operators spend on deployments and governance. Onboarding MicroShift to Shipa offers some nice benefits by making it possible to manage multiple clusters from an administration and operations perspective.

An unreliable, semi-broken and unresponsive website is an excellent way to lose leads and visitors — regardless of how aesthetically pleasing or well-designed, the visual elements are.

Over the past decade, we’ve seen more initiative to deliver faster internet to regions of the world that were previously devoid of it. With online communities expanding and more people becoming receptive to online shopping, ensuring your site’s dependability is now more important than ever. 

One way to achieve this is by employing uptime and downtime monitoring tools. This guide will examine the best ways to get alerts when something goes wrong and your website falters.

Why Is Website Uptime Monitoring Important?

Downtime is bound to occur occasionally. Nonetheless, the goal is to minimize it. The longer the downtime occurs, the more traffic and potential clients you lose. A dysfunctional website is also detrimental to your credibility and reputation. People may associate your website’s unreliability with your real-world products or services.

With web developers charging an average of $200 per hour, high-quality websites can be expensive to build and maintain. Nevertheless, it’s often worth the investment. However, an unreliable website can backfire on you. Instead of attracting more customers, it could potentially repel them. This can result in lost revenue.

An uptime monitoring solution can help you prevent or reduce these losses. It verifies if your website is up and functional and notifies you if it’s not. This allows you to troubleshoot the issue and get your website back up and running as soon as you’re alerted. The most common issues behind your website’s downtime include: 

  • Server faults;
  • Network outages;
  • Power outage;
  • Traffic spikes;
  • Cyberattacks;
  • Domain name issues;
  • An erroneous web application deployment;
  • Increased server loads;
  • DNS Resolve issues;
  • Human error.

Thus, you must employ a dependable tool that detects downtime or any interruptions related to your website as soon as they occur. They are must-have tools for web designers, developers, and network administrators. However, not all of them are built the same. So how do you identify the best uptime monitoring tools?

Essential Features of Uptime Monitoring Tools

Uptime monitoring tools typically detect interruptions by running network tests such as pings and trace routes. You could practically monitor your website’s uptime by constantly running these tests yourself. 

However, this isn’t an efficient way to monitor your website’s uptime. A comprehensive uptime monitoring tool will automatically monitor your website’s uptime in the background. It will then alert you through various channels as soon as it senses that your website may be down. 

Furthermore, high-quality uptime monitoring solutions tend to offer additional information regarding your website’s uptime/downtime and its performance. These tools commonly feature dashboards, status pages, badges, exportable records, etc., to help you keep track of your site’s overall health.

9 Best Features of an Uptime Monitoring Solution

The ideal uptime monitoring tool or service should feature: 

  1. Website security features that notify of and repel potential cyber attacks;
  2. 24/7 uninterrupted background website monitoring;
  3. Multi-channel alerts (email, SMS, push notifications, instant messages, social media, etc.);
  4. Report generation;
  5. 24/7 customer support available through different channels (email, phone, chat, etc.);
  6. Be capable of monitoring multiple websites and proxies at the same time;
  7. Offer insights and suggestions to improve your website’s performance;
  8. Be affordable;
  9. High customizability should allow you to choose which features to enable and disable.

Another optional feature to look out for is public status pages that your clients can access to determine if all your services are up and running. GetWeave is an excellent example of this. The website features a well-organized systems status page where customers can check if all of Weave’s services are functional. 

Nevertheless, you can use the above information as a buying guide when assessing potential uptime monitoring tools. The rest of this guide will supply a few suggestions as to which tools you should use for your website.

3 Best Website Uptime Monitoring Tools 

Some of the best uptime monitoring tools for website downtime alerts include:

1. Uptrends

Uptrends isn’t just a downtime detection tool; it’s a complete web performance monitoring solution. It will notify you as soon as it detects any disturbance in your website’s performance. It features highly customizable checks. For instance, you can set performance check limits for load times. Uptrends will notify you instantly if your website takes too long to load.

You can also configure from which locations you want it to monitor your website. Uptrends will then point you to where your website usually suffers performance dips in the real world. 

The service uses multiple communication channels to send users notifications: email, phone calls, and SMS. Alternatively, you can download one of Uptrend’s mobile applications and receive push notifications. Additionally, you can integrate Uptrends with messaging and communication applications such as PagerDuty, Slack, and Microsoft Teams.   

Another impressive Uptrend feature is its ability to emulate your website’s performance on different browsers. It runs Google Chrome, Mozilla Firefox, and Microsoft Edge on its servers. Thus, you can compare how your website runs on these web browsers without installing them on your servers or computer. 

Uptrends supplies users with various charts, reports, and graphs to help identify sudden spikes or dips. Waterfall reports display the complete page-load from the initial request to the last download. This allows you to compare the history of your website’s performance element by element. It comes with three price plans whose costs depend on the number of monitors you would like. Starting at $16.21 (at the time of writing) the Starter Plan is the most affordable.

2. Oh Dear

Oh Dear is a slightly cheaper option than Uptrends, with the most affordable plan starting at $12 per month (at the time of writing). However, while Uptrends offers a 30-day free trial, Oh Dear only provides a 12-day trial period. Nevertheless, Oh Dear’s interface is a lot cleaner and more minimal. 

Since Oh Dear runs servers in different locations across the globe, it can track how your website performs in various regions. Oh Dear will scan through your website and index all the pages. If it detects any issues, it will alert you immediately. 

Oh Dear also features a continuous certificate monitoring function. Site owners who are concerned with their website’s security may find this feature to be especially useful. It will verify your SSL certificate expiration dates and alert you of any changes.  

Oh Dear’s public status page enables your clients to keep track of your website’s availability.

Oh Dear uses email and SMS text messages to alert site owners of any issues. It also features integrations with communications and social media applications such as Telegram, Discord, Slack, Microsoft Teams, etc. Oh Dear ensures that messages are as detailed and user-friendly. This makes it easier to troubleshoot and find the origin of your problem. Oh Dear is more than a worthy alternative to Uptrends. 

3. WP Umbrella

WP Umbrella is a little different from the previous entries. It’s intended to help users manage and monitor multiple WordPress sites. Thus, it is far more particularized in its approach to website uptime monitoring. Again, as is the primary function of the uptime monitoring tool, it offers a real-time alert system that will contact you through email, SMS, Slack, etc. 

WP Umbrella employs a simple minimal UI. Its main screen consists of a dashboard that allows you to view all your WordPress websites. By default, this dashboard features four columns: Site, Uptime, Speed, and Issues.

WP Umbrella will alert you of any outdated or erroneous plugins or themes. While it doesn’t offer dedicated public status pages, it does have a client report generation feature. You can automatically send these reports to your various subscribers or clients when your website is down. 

WP Umbrella is the most affordable option on this list. Users are charged $1.99 per month (at the time of writing) for each website monitored. In addition, WP Umbrella offers a 14-day trial and does not require your credit card details. It’s an excellent option for anyone running a WordPress website or two.

Conclusion

This guide has only explored three possible uptime monitoring solutions. They won’t only assist you in detecting downtimes, they can also help you find the reason your site may be slow.

These solutions are an excellent place to start. But there are many other options coming to market all the time. You may find that this is the first step to converting more leads and reducing your bounce rate.

The General Data Protection Regulation (GDPR) was big news for companies when it came into effect in 2018. It aimed to put more controls on how organizations manage the personal data of their EU-based users. Since the law’s enactment in 2018, some US states, such as California and Virginia, followed suit and passed their own data privacy laws for their respective residents. Companies that do business in those regions now have to ensure they comply with these legal requirements.

This post is the third in a series about what developers need to keep in mind when sorting out security and compliance for their application. The first article in this series covered how to build security for user communications, the second was about compliance certifications and regulations for SaaS apps, and this one is all about GDPR and customer communications. GDPR and similar regulations cover all communications from a company to its customers and prospects, including marketing and transactional notifications. If you are considering sending notifications to the users of your SaaS application, whether via email, push, or a Slack bot, you need to keep GDPR in mind when building your service.

Many companies are looking to low-code and no-code platforms to build apps in the visual environment. They provide the opportunity for faster app development and reduce the dependence on highly skilled developers. Companies may hire less experienced or only minimally trained staff (I’ll call them citizen developers) to meet service gaps and to respond to skills shortages, ensuring their larger dev team can focus on more advanced projects.
