10 alternatives à Docker pour votre application SaaS

Découvrez 10 alternatives à Docker pour votre application SaaS afin d’améliorer votre expérience de développement et de déploiement.

Les technologies Docker ont révolutionné le paysage de gestion de l’infrastructure de telle sorte que Docker est maintenant devenu synonyme de conteneurs. Il est important de comprendre que tous les dockers sont des conteneurs, mais tous les conteneurs ne sont pas des dockers. Bien que Docker soit la technologie de conteneur la plus couramment utilisée, il existe plusieurs autres alternatives à Docker. Dans ce blog, nous explorerons les alternatives Docker à votre application SaaS. Qu’est-ce que Docker? Docker est une plate-forme de conteneurisation d’applications très populaire dans les cercles informatiques. Ce logiciel open source permet aux développeurs de facilement empaqueter des applications avec leurs dépendances, le système d’exploitation, les bibliothèques et autres ressources liées à l’exécution dans des conteneurs et de les déployer automatiquement sur n’importe quelle infrastructure. Avec l’architecture cloud-native et les environnements multi-cloud devenant des choix populaires pour la plupart des organisations, Docker est le choix le plus pratique pour construire, partager, déployer et gérer des conteneurs à l’aide d’API et de commandes simples dans ces environnements.

Développement collaboratif de nouvelles fonctionnalités avec microservices

Le développement collaboratif de nouvelles fonctionnalités avec microservices offre une solution flexible et évolutive pour répondre aux besoins des entreprises.

Dans une architecture de microservices, le code est divisé en petites unités. Ces morceaux de code peuvent être développés en isolation et expédiés indépendamment en production, ce qui réduit les dépendances entre les équipes – le résultat: un développement de fonctionnalités rapide et un temps de mise sur le marché plus rapide.

Bien que l’architecture des microservices apporte de nombreux avantages, la réalité est que ces avantages tendent à diminuer à l’échelle. En particulier, plus un organisme a de microservices, plus il est difficile de s’assurer que les modifications fonctionnent ensemble dans leur ensemble.

En tant qu’informaticien enthousiaste, je sais que l’architecture microservices est une solution très populaire pour les développeurs. Cette architecture consiste à diviser le code en petites unités qui peuvent être développées et mises en production indépendamment, ce qui réduit les dépendances entre les équipes et permet un développement plus rapide des fonctionnalités et une plus grande rapidité sur le marché.

Cependant, il est important de comprendre que ces avantages diminuent à mesure que la taille de l’organisation augmente. Plus il y a de microservices, plus il est difficile de s’assurer que les changements fonctionnent ensemble. C’est pourquoi il est important d’utiliser une base de données pour gérer ces microservices. Une base de données permet d’organiser et de stocker les informations sur les microservices, ce qui facilite leur gestion et leur maintenance. Elle permet également aux développeurs de voir comment les différents microservices interagissent entre eux et comment les changements affectent le système dans son ensemble.

Enfin, une base de données peut également être utilisée pour surveiller et analyser l’utilisation des microservices. Les développeurs peuvent ainsi suivre l’utilisation des microservices et identifier les problèmes potentiels avant qu’ils ne deviennent trop importants. De plus, les données collectées peuvent être utilisées pour améliorer les performances des microservices et pour prendre des décisions basées sur des données. En bref, une base de données est un outil essentiel pour gérer et surveiller les microservices à grande échelle.

Craft CMS is increasing in popularity, and as it does, the previously relatively scant range of plugins is growing rapidly.

There are plugins for Craft ranging from simple field utilities to the full ecommerce solution provided by Pixel & Tonic — the makers of Craft.

An early decision that has borne fruit for Craft has been the plugin licensing model. Paid plugins for Craft charge an initial license fee and then a reduced annual renewal price for updates. This ongoing payment structure ensures plugin maintenance is economically viable for developers, and as a result, Craft plugins tend to be updated more often and are abandoned less.

The best plugins depend very much on the site you’re developing and what you’re trying to achieve. However, some are so universally useful that I install them on virtually every site I build; here’s a list.

1. Redactor

Installing Redactor is a no-brainer when it comes to picking your plugins. Maintained by Pixel & Tonic, it’s a rich text field that extends Craft‘s basic text input. It’s so useful it may as well be part of the core Craft code.

One of the best features is the ease with which Redactor can be customized. Just duplicate the settings file inside the config directory and edit its contents to alter what editing options are available; it’s simple to create anything from a field with a bold option to a full rich text editor. In addition, each Redactor field can be set to use any of the settings files.

Free

2. Retcon

When you’re outputting code from a rich text field like Redactor, you’ll get clean HTML output — which most of the time is what you want. However, if you’re using something like Tailwind, those classes are non-negotiable. I’m not a fan of Tailwind, but I am a fan of using classes in my CSS selectors instead of element names.

Retcon is an invaluable plugin that extends Twig filters to supply a host of options when you’re outputting content. It can add classes to elements, insert attributes, modify the element type, and tons more.

Free

3. Venveo Bulk Edit

During the life of a site, there’s a good chance that you’re going to have to alter fields and sections after the content is in. It’s a common problem if you’re importing data from another platform using FeedMe, or if you have an indecisive client, or even if the site is simply growing.

Venveo Bulk Edit is a plugin that integrates closely with the Craft UI and allows you to edit the contents of multiple entries at once. This plugin has saved me hundreds of hours that would otherwise have been spent painstakingly editing entries one at a time.

Free

4. Super Table

At some point, you’re going to need a configurable list of inputs. Maybe you’re creating a list of documents to download, building a directory, or even your site navigation. You could create a new channel and then add the entries as an entry field, or even set it up with a matrix field, but this is awkward to edit even with Craft 3.7’s new editing experience.

I’m a big fan of opting for the simplest solution, and in this case, the simplest option is a table field. Unfortunately, Craft’s built-in table field has limited field type support. Super Table, on the other hand, supports almost anything, giving you a powerful, orderable set of fields.

Free

5. No-Cache

Craft has a really powerful caching system. It allows you to cache whole or partial templates, and it‘s intelligent enough to know when you’ve edited content that has been cached so that it can be re-cached.

Understanding Craft’s caching is vital; as a very general guide, dynamic content benefits from caching, but static content does not.

However, you will regularly encounter situations where you want to opt out of the caching. A blog post, for example, could be cached, but the time since it was posted must not be, or every post would appear to have been published “today” until the cache is refreshed.

The No-Cache plugin adds a couple of Twig tags that allow you to temporarily opt-out of the cache. This means that you can cache larger sections of your templates, simplifying your caching decisions considerably while still being able to fine-tune what is cached.

Free

6. Retour

Sooner or later, you’re going to have users hitting 404 errors. If you’re restructuring a site and changing the architecture, it will be sooner. To avoid breaking the UX and SEO, you need to add redirects.

Retour is a helpful plugin that sits in your dashboard side menu. Anytime a user triggers a 404, Retour will flag it up, so you can decide how to redirect the URL in the future.

$59 for the first year; $29/year for updates after that

7. Sherlock

One of Craft’s big strengths is its security. A lot of attention has gone into making sure that the core installation uses best practices. However, as with any CMS, potential security vulnerabilities start to creep in as soon as you introduce 3rd-party code (WordPress’ biggest vulnerability by far is its plugins).

You only need to look at the size of the vendor directory in your installation to see how many 3rd-party dependencies your site has. Even a small site is a house of cards.

Sherlock is a security scanner that performs a number of different tasks to help you stay secure, from checking on security threats in 3rd-party scripts to checking directory permissions. The paid version will even let you limit IP addresses if your site comes under attack — although your hosting company may well do this for you.

Lite: Free
Plus: $199 for the first year; $99/year for updates after that
Pro: $299 for the first year; $149/year for updates after that

8. Imager X

Craft’s built-in image transforms are a little limited. For example, they only work with actual assets, not remote images.

Imager X is an excellent plugin that, among many benefits, allows you to transform remote images. In addition, its refined syntax is perfect for coding complex art direction.

Imager X isn’t cheap, but considering the enormous importance of image optimization, unless you have a straightforward set of images to manipulate, it’s an investment you’ll be glad you made.

Lite: $49 for the first year; $29/year for updates after that
Pro: $99 for the first year; $59/year for updates after that

9. SEOMatic

SEOMatic is the SEO solution most Craft developers default to, including Pixel & Tonic themselves.

You’ll need to define the basics in its settings, and you may find yourself creating extra fields specifically for it to pull data from, but the handy progress bars on its dashboard page will give you an overview of what’s set and what needs to be done.

SEOMatic is another premium plugin, but implementing it is far simpler and cost-effective than digging through all those meta tags and XML files yourself.

$99 for the first year; $49/year for updates after that

Must-Install Craft CMS Plugins

The Craft ecosystem is rapidly growing, and the diversity of the plugins available increases as Craft is utilized for more and more sites.

But despite the lure of shiny new plugins, there are some tools that I return to again and again either because they elegantly fill a gap in the core Craft feature set or because I’ve tried them, and I trust them to be robust.

These are the plugins that I have found most useful in the last couple of years, and installing them is the first thing I do when I set up a new Craft installation.

Is your organization ready to move containerized workloads into production or yet struggling with these challenges? Adopting complex stateful workloads with many dependencies, deploying containerization tooling without well-framed DevOps practices, and becoming gripped into vendor lock-in faster may be a few of such challenges. Having the right DevOps team in place and finding out how Kubernetes integrates with your company’s technological infrastructure to undergo effective legacy application modernization should be the way out. As an organization, you should consider if you have the requisite roles and skillsets before adopting new technologies. You must decide on runtime and orchestration engines in technical terms while selecting containerization workloads with utmost care and attention.

With more than 70% of organizations running containerized applications in production, Kubernetes has emerged to be one of the most sought-after methods to organize containers. Here are a few of the Kubernetes best practices that ensure its adoption truly advancing container deployment.

Overview

The formula is the heart of an Excel file. And of course, we all want to do correct calculations and deliver accurate results. When there is something wrong, we want to trace back to those referenced cells to find the root cause. Excel natively has a built-in convenient formula dependent/precedent trace feature, it highlights the dependent/precedent cells and displays arrows to indicate the relationships. This helps users to trace back and find any error formulas easily.

Now, when bringing the spreadsheet online, we can do more. We can display the relationships in a custom way that is most useful according to the application context, or bring them to a different service or application for doing the validation programmatically.
