In the previous blog post about Kubernetes autoscaling, we looked at different concepts and terminologies related to autoscaling such as HPA, cluster auto-scaler, etc. In this post, we’ll do a walkthrough of how Kubernetes autoscaling can be implemented for custom metrics generated by the application.

Why Custom Metrics?

The CPU or RAM consumption of an application may not indicate the right metric for scaling always. For example, if you have a message queue consumer that can handle 500 messages per second without crashing. Once a single instance of this consumer is handling close to 500 messages per second, you may want to scale the application to two instances so that load is distributed across two instances. Measuring CPU or RAM is a fundamentally flawed approach for scaling such an application and you would have to look at a metric that relates more closely to the application’s nature. The number of messages that an instance is processing at a given point in time is a better indicator of the actual load on that application. Similarly, there might be applications where other metrics make more sense and these can be defined using custom metrics in Kubernetes.

SAP, éditeur européen leader des logiciels d’entreprise annonce qu’Ornikar, l’auto-école leader en France, s’appuie avec succès sur la solution SAP Business ByDesign pour répondre à ses enjeux de structuration, de croissance et de changement d’échelle.

Se structurer avec le cloud SAP

En 2019, ORNIKAR choisit la solution SAP Business ByDesign pour mettre en place un ERP flexible et solide capable de soutenir le pilotage de ses activités quotidiennes dans un contexte de forte croissance.

Au préalable, la gestion de l’entreprise était encadrée par un cabinet d’experts comptables externe limité à la production des documents légaux et sans système de pilotage propre. Afin d’accélérer la partie financière et avec la volonté d’avoir une information plus fiable et en temps réel, l’auto-école a décidé d’opter pour l’ERP Cloud pour PME de SAP. Ce dernier permet à l’entreprise de se professionnaliser tout en gardant une grande simplicité d’utilisation grâce à une intégration d’applications périphériques.

En optant pour SAP Business ByDesign, ORNIKAR a d’abord fait le choix du Cloud. En effet, la solution devait être en adéquation avec l’ADN Tech de l’entreprise et être accessible à tout moment, partout et sur tous les supports. Un impératif confirmé par la crise sanitaire et qui a permis d’avoir un suivi en continu des opérations notamment financières.

Déploiement en deux mois, des gains immédiats

Intégrée par Ubister en seulement deux mois, la solution de SAP offre de nombreux gains à ORNIKAR après seulement une année d’exploitation. Elle offre ainsi une meilleure vue du business, une plus grande efficacité opérationnelle, rapidité d’obtention des informations et fiabilité des informations. Elle a également permis la mise en place d’une comptabilité analytique pour plus de granularité dans le pilotage.

Timothée Dufour, CFO d’ORNIKAR, explique : « C’est un investissement qui représente aujourd’hui un ROI très positif par rapport au coût de la licence SAP Business ByDesign et à tous les avantages que nous pouvons avoir de notre côté. Avec l’aide de SAP et de notre intégrateur Ubister, nous avons réussi une implémentation rapide et alignée avec les objectifs de structuration, de croissance et de scale de l’entreprise. Nous sommes désormais équipés pour répondre à la forte croissance que connait ORNIKAR en France et à l’international. »

Place à l’international et l’assurance

ORNIKAR a de grandes ambitions de développement à l’international et s’est déjà implantée en Espagne avant de s’étendre à d’autres pays d’Europe et  au continent américain. L’entreprise vient également de lancer la distribution d’un produit d’assurance automobile avec l’ambition  d’en devenir leader en France.

ORNIKAR entend ainsi renforcer sa fonction finance avec SAP au cours des 3 prochaines années.

À propos d’ORNIKAR

The new year is often packed with resolutions. Make the most of those goals and resolve to design better, faster, and more efficiently with some of these new tools and resources.

Here’s what new for designers this month.

Radix UI

Radix UI is an open-source UI component library for building high-quality, accessible design systems and web apps. It includes examples and guidelines for all kinds of user interface elements that provide guidance and really make you think about accessible website design. (And everything is usable!)

Froala Charts

Froala Charts is made to help you create data visualizations for web or mobile apps. Build any chart you can imagine – bar, line, area, heat map, sankey, radar, time series, and more. Plus, you can customize anything and everything, so it all matches your brand. This premium tool is enterprise-level and comes with a one-time license fee.

CSSfox

CSSfox is a collection of designs that you can use for inspiration. The curated community project includes posts, reviews, and award nominees and winners.

Pattern Generator

Pattern Generator is a tool to create seamless and royalty-free patterns that you can use in projects. Almost every element of the pattern design is customizable, and you can “shuffle” to get new style inspiration. Design a pattern you like and export it for use as a JPG, PNG, SVG, or CSS.

Type Scale Clamp Generator

Type Style Clamp Generator helps you create a visualize a typographic scale for web projects. Pick a font and determine a few other settings and see the scale right on the screen. You can even put in your own words to see how they would look. Then, flip to see how sizes appear on different devices. Find a scale you like and snag the code with a click.

Flowdash

Flowdash is a premium app that helps you build custom tools, data sets and streamline your business operations with one tool. Manage data and processes without code. The tool combines a spreadsheet’s familiarity with a visual workflow builder, plus built-in integrations to automate repetitive tasks so your team can focus on what matters.

Scale

Scale is a website that provides new and open-source illustrations that you can use for projects. Maybe the illustration generator’s neatest part is that you can change the color with just a click to match your brand. Then download the image as an SVG or PNG.

Pe•ple

Pe•ple is a tool that adds a “customizable community” to any website to help grow your fanbase and provide a boost to SEO. It allows you to integrate chat, commenting, emojis, and passwordless login, among other things.

K!sbag: Free Minimal Portfolio Template

K!sbag is a free minimal website template that’s made for portfolio sites. (Did you resolve to update yours in 2021?) It includes 6 pages in a ready-made HTML format and PSD.

Merico Build

Merico Build is like a fitness tracker for code. It uses contribution analytics to empower developers with insight dashboards and badges focused on self-improvement and career growth. Sign up with tools you already use – Github or Gitlab.

Automatic Social Share Images

Automatic Social Share Images solves a common website problem: Missing or broken images when posts or pages are shared on social media. This tutorial walks you through the code needed to create the right meta tags so that popular social media channels pick up the image you want for posts. The best part is this code helps you create a dynamic preview image, so you don’t have to make something special every single time.

Animated SVG Links

Animated SVG Links can add a little something special to your design. This pen is from Adam Kuhn and includes three different link styles.

Blush

Blush helps you create illustrations. With collections made by artists across the globe, there’s something for everyone and every project. All art is customizable, so you can play with variations to create something unique.

Palms

Palms is a set of 43 sets of hands to help illustrate projects. Each illustration is in a vector format and ready to use.

Tabbied

Tabbied allows you to create and customize patterns or artwork in a minimal style for various projects or backgrounds. Tinker with your artwork and patterns and then download a free, high-resolution version.

How to Create Animated Cards

How to Create Animated Cards is a great little tutorial by Johnny Simpson that uses WebGL and Three.js to create a style like those on Apple Music. The result is a stylish modern card style that you can follow along with the CodePen demo.

Bandero

Bandero is a fun slab with a rough texture and interesting letterforms. The character set is a little limited and is best-suited for display use.

Magilla

Magilla is a stunning modern serif with great lines and strokes. The premium typeface family has six styles, including an outline option.

Roadhouse

Roadhouse is one of those slab fonts that almost screams branding design. The type designer must have had this in mind, too, with stripe, bevel, inline, half fill, outline, drop extrude, and script options included. (This family is quite robust, or you can snag just one style.)

Street Art

Street Art is for those times when a graffiti style is all that will do. What’s nice about this option – free for personal use – is that the characters are highly readable.

The post Exciting New Tools for Designers, January 2021 first appeared on Webdesigner Depot.

The start of the year is always a good time to reassess priorities and consider new approaches, but 2021 is more of a reset than we expected this time last year. 2020 is unlikely to go down in anyone’s autobiography as the best year of their life, but it has done something positive: it’s prepared the ground for rapid change in the next 12 months.

More than any other year in our lifetimes, 2021 is set to be revolutionary, with emerging trends that will last well into the new decade. Here’s what we think you can look forward to around the next corner.

1. The End of Minimalism

Minimalism has been the de facto approach to web design for the last decade because it works.

But design reflects the zeitgeist. Where minimalism once felt clean and fresh, it’s starting to feel dull and uninspired. There have been a few false-starts breaking out of the long-term trend, but thanks to the pandemic, 2021 will be the year minimalism finally folds — at least for a while.

Prior to coronavirus-mandated lockdowns worldwide, there were already signs of a more vibrant, more decorative, more joyful approach to design. Simple typefaces have been replaced with more decorative examples — faces that use ink-traps to fake 3D effects are surprisingly popular.

trends are cyclical, and the wheel always turns

One of the biggest aspects of this blossoming trend is the move away from Material Design-style flat color not just to gradients but to multi-color gradients and even animated gradients. Even Apple, the last bastion of the clean white-box approach, jumped on the gradient bandwagon with its Big Sur branding.

One of the few things COVID-19 hasn’t slowed is the adoption of new web technology, and CSS, in particular, has had some major developments in the last year. CSS Grid is now a practical technology, and our ability to code standards-compliant designs that aren’t dependent on hierarchical boxes is greatly enhanced.

After more than a year of pretty grim news for most people, much of the world will be vaccinated over the next twelve months, and life will rapidly return to normal. The last global crisis on this scale was the 1918 influenza pandemic, and it led directly to the decade known as the Roaring Twenties.

Minimalism was already dipping in popularity — trends are cyclical, and the wheel always turns — but lockdown, or perhaps more precisely the end of lockdown, is the catalyst for significant change.

2. The Decline of WordPress

In Autumn 2020, something entirely unexpected happened: The W3C announced the platform its new web presence would be built on, and WordPress — the previous choice of the web’s steering committee — didn’t even make the list of finalists.

Due to accessibility concerns, the W3C development team opted to migrate away from WordPress to Craft CMS. The decision was met with a mixture of glee and outrage. But whether you agree with the decision or not, it’s hard to see it as anything other than yet another symptom of WordPress’ decline.

WordPress faces a triple threat: there are web builders that do an adequate job for low-end web projects; there are newer rivals like Craft that outperform WordPress as a CMS; there’s a growing interest in alternate approaches, like Jamstack.

So will it all be over for WordPress in 2021? Not even close. There are myriad reasons WordPress will continue to be the choice of designers and developers for years to come. Tens of thousands of professionals worldwide have invested their whole careers in WordPress; there are millions of themes, plugins, templates, and build processes that are tightly woven into the WordPress ecosystem. What’s more, there are millions of sites with substantial content archives powered by WordPress [WebDesignerDepot is one such site].

WordPress reportedly powers approximately 37% of the web, and it will still be the dominant CMS in 2022. But it’s unlikely to grow beyond that 37%, and by 2030 its market share will be in rapid contraction.

2020 was the high-tide mark for WordPress

But for all its faults — and it’s undeniable that WordPress is full of faults — WordPress is the best of the web; it has given a voice to millions of people, launched countless careers, and empowered entrepreneurship worldwide.

2020 was the high-tide mark for WordPress, but it’s not an extinction-level event — even the much-maligned Flash, which was killed dead in a matter of months by the first generation iPhone, limped on until a few weeks ago.

WordPress will have to find a niche and accept a smaller market share; in doing so, it will address the single biggest complaint that anyone has about WordPress: that it’s trying to do too much.

WordPress is one of the great success stories of the web. In a decade, it may have to settle for powering just 10% of the web — a level of failure most of its rivals can only dream of.

3. The Digital Currency Explosion

2021 is undoubtedly the year that cryptocurrency goes mainstream. In 2020 Bitcoin grew by almost 400%; currently valued at around $35k, conservative predictions for a December 2021 valuation are $100k, with five-year predictions as high as $1m. And Bitcoin isn’t the only cryptocurrency; the value of developer-friendly Ether has jumped by more than 50% in the first few weeks of 2021.

In the US, the incoming Biden administration is preparing a multi-trillion dollar relief package, which many believe young Americans will invest in cryptocurrency. Perhaps more importantly, large investment banks are now pumping hundreds of millions in digital currencies. PayPal and Visa are both in the advanced stages of adopting blockchain technology.

The biggest threat to the new digital economy is the volatility of cryptocurrency. You cannot price services in XRP if XRP’s dollar price could crash at any time — as it did a few weeks ago.

And so there are two routes in which this trend will unfold for ecommerce. Either pricing will remain in dollars, and the equivalent price in various cryptocurrencies will be calculated in real-time. Or, transactions will make use of stablecoins like Tether that are tied to the value of the US dollar.

Cryptocurrency is the latest gold-rush, and whether you think it’s the chance of a lifetime or yet another Ponzi scheme, it will become increasingly high-profile in ecommerce throughout 2021.

4. No More Video Calls and also More Video Calls

2020 was the year of Zoom. Its growth from bit-player to overtaking Skype is a material lesson for entrepreneurs that every obstacle is an opportunity.

every obstacle is an opportunity

Over the last year, we’ve discovered two things: meetings are more creative in person, and office costs are significantly reduced when staff work remotely.

There’s going to be a shift in the business landscape this year. Remote working will continue to be normal for years to come as businesses enjoy rent savings. Video calls will still be common for quick update meetings. But expect to travel to physical meeting places periodically for in-depth strategic planning.

Expect to see major cities with deserted office buildings and a rapid expansion of co-working spaces, especially those with meeting spaces — if WeWork can hold on a little longer, there may be light at the end of the tunnel.

As a web professional, you’re in a unique position to thrive in the new business world, even more so if you’re a freelancer. Remember, if you’re working onsite, be mindful of your physical health, and if you’re working remotely, be mindful of your mental health.

What Do You Think?

No one saw 2020 coming. Sometimes world events are outwith our control, and we have to hang on and hope it gets better. It’s been a tough 12 months, and the truth is we’re not through it yet.

But the 2020 coronavirus pandemic is the first pandemic in human history that we’ve had the technology to shorten.

2021 offers the opportunity for enormous change. Will designers look for new, more decorative approaches? Will we replace our technology stack? Will you be billing clients in Ether this year? Will you suffer the misery of a packed evening commute ever again?

We are well past the experimental stage with the cloud. It’s become mission-critical, and we have entered a stage where our applications and services need to take advantage of the globally distributed nature of the cloud and deliver on the expectations of our consumers.

Legacy relational databases are simply not built for the cloud. They are difficult to scale in this environment and costly to maintain their uptime. NoSQL stores were built to address legacy limitations; however, they fall short when it comes to providing consistent transactions. They are casually consistent. Some of the most successful global organizations have purpose-built databases that achieve the reliability of the relational store with the benefits of scale and global coverage that comes with the cloud. These databases are a new breed called Distributed SQL.

Overview

EclipseLink has two types of caches: the shared cache (L2) maintains objects read from database; and the isolated cache (L1) holds objects for various operations during the lifecycle of a transaction. L2 lifecycle is tied to a particular JVM and spans multiple transactions. Cache coordination between different JVMs is off by default. EclipseLink provides a distributed cache coordination feature that you can enable to ensure data in distributed applications remains current. Both L1 and L2 cache store domain objects.

“Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.” — redis.io
