Passer de Docker Swarm à Kubernetes peut être une transition complexe, mais elle offre une meilleure mise à l’échelle et des fonctionnalités avancées. Découvrez comment faciliter cette transition.

Comprendre le changement

Making the Transition

The transition from Docker Swarm to Kubernetes requires careful planning and execution. Organizations should consider the following best practices when making the switch:

  • Understand the differences between Docker Swarm and Kubernetes. This will help ensure that the transition is seamless and that the organization is taking full advantage of Kubernetes’ capabilities.
  • Evaluate existing infrastructure and applications. This will help determine if Kubernetes is the right fit for the organization’s needs.
  • Create a plan for the transition. This should include a timeline, budget, and resource allocation.
  • Test the new system before going live. This will help ensure that everything is working as expected.

Benefits of Kubernetes

Kubernetes offers several advantages over Docker Swarm, including scalability, reliability, and flexibility. Kubernetes is designed to handle large-scale deployments with ease, allowing organizations to quickly and easily scale their applications as needed. It also offers a robust set of features, such as rolling updates, self-healing capabilities, and automated deployment. Finally, Kubernetes is highly extensible, allowing organizations to customize their deployments to meet their specific needs.

Architecture de Kubernetes

Kubernetes est une plateforme open source conçue pour automatiser le déploiement, le dimensionnement et l’exploitation des conteneurs d’applications. Il offre une plus grande flexibilité, un ensemble de fonctionnalités plus riche et un vaste écosystème, ce qui en fait le choix préféré des déploiements à grande échelle et d’entreprise. La transition de Docker Swarm à Kubernetes nécessite une planification et une exécution minutieuses. Les organisations doivent prendre en compte les meilleures pratiques suivantes lors du passage à Kubernetes : comprendre les différences entre Docker Swarm et Kubernetes, évaluer l’infrastructure et les applications existantes, créer un plan de transition et tester le nouveau système avant de le mettre en production.

Avantages de Kubernetes

Kubernetes offre plusieurs avantages par rapport à Docker Swarm, notamment la scalabilité, la fiabilité et la flexibilité. Il est conçu pour gérer facilement les déploiements à grande échelle, ce qui permet aux organisations de redimensionner rapidement et facilement leurs applications selon leurs besoins. Il offre également un ensemble robuste de fonctionnalités, telles que les mises à jour en roulement, les capacités de réparation automatique et le déploiement automatisé. Enfin, Kubernetes est extrêmement extensible, ce qui permet aux organisations de personnaliser leurs déploiements en fonction de leurs besoins spécifiques.

Conclusion

Kubernetes est devenu la solution préférée pour les déploiements à grande échelle et d’entreprise grâce à ses avantages en matière de scalabilité, de fiabilité et de flexibilité. Bien que la transition de Docker Swarm à Kubernetes puisse être complexe et exiger une planification minutieuse, elle offre des avantages considérables pour les organisations qui souhaitent tirer parti des fonctionnalités avancées de Kubernetes. Les organisations doivent donc prendre le temps d’examiner attentivement les avantages et les inconvénients de chaque solution et de choisir celle qui répond le mieux à leurs besoins.

Today, the cloud environment has been chosen by many business solutions as the major hosting environment for their applications. They can either choose Software-as-a-service (SaaS), Platform-as-a-service (PaaS), or Infrastructure-as-a-service (IaaS) different solution types to build up solutions to meet business requirements. However, storing business data in the Cloud environment will have a great challenge in exposing business data to the public. As the concerns data security issues, every Cloud platform vendor provides a different solution for data security. Understanding the similarity and differences in those solutions will help the business clients choose the proper solution for the business applications.  

This article will discuss the primary solution use cases and major differences in secret key management among the Microsoft Azure, Amazon AWS, and Google Cloud Platform for managing secret keys, certificates, and data encryptions.  Although a platform could provide a similar solution or indirect solution for a specific use case, it will still be compared as a difference as long as it is not a commonly used use case.

Whether you’ve worked with a few WordPress themes to design websites or worked with many of them, you’ll no doubt agree that plenty of WordPress themes that are visually gorgeous on the front end can be terribly unattractive and extremely awkward to use on the backend. 

Working with a WordPress theme can sometimes be difficult, but it can be different.

Want proof? Look no further than with BeTheme. 

BeTheme, with 260,000+ sales and counting and a 4.83-star user rating, is one of the top 5 best-selling WordPress themes of all time.

In this article, we’ll show you one of the many reasons why this is the case by focusing on how BeTheme’s backend is designed to make web design tasks more manageable.

Enhance your workflow experience with a WordPress theme backend that won’t stress you out 

Once you install BeTheme, you’ll almost immediately notice it’s different. Instead of a drab and often unintuitive WordPress backend, you’ll suddenly be confronted with a clean, well-organized dashboard and toolset.

You haven’t actually lost anything. WordPress, with its impressive assortment of content management tools, is still there. Be’s backend is a visually appealing space in which you will take pleasure to work.

If only the rest of WordPress could follow suit.

If you haven’t worked with BeTheme recently (or at all), why not let us walk you through several of its most helpful backend features.

Starting with:

1. Dashboard Design

BeTheme’s dashboard is conveniently located directly beneath the main WordPress Dashboard link. So you won’t waste time sifting through the sidebar trying to find your theme’s settings, and everything displayed in the dashboard is designed to help you get the most out of your WordPress theme. 

Clicking on the BeTheme or the Dashboard link gives you immediate access to the following: 

  • Theme registration information
  • BeTheme’s step-by-step website creator
  • A Navigation bar that directs you to BeTheme’s frequently used tools
  • Plugin status and updates and new features announcements
  • The latest additions to BeTheme’s ever-growing library of pre-built websites
  • Beloved BeTheme integrations

It takes a minute to fully appreciate how helpful this dashboard will be. 

BeTheme

2. Dark/Light Mode

Research on dark mode benefits is inconclusive. But since so many people seem to like it, it is offered as an option in many popular apps and devices.

Dark mode users will tell you that they experience less eye strain, they sleep better, and their device’s batteries last longer than is the case with light mode.

BeTheme’s backend offers a dark mode option, and you are encouraged to try it.

If you feel it beneficial, so much the better, and you needn’t concern yourself with what the research indicated, or didn’t indicate.

BeTheme

3. Step-by-Step Website Creator

When you first install a WordPress theme, it’s not uncommon to spend some time trying to figure out what to do next. The theme’s advertisements may highlight a selection of impressive demos, but where are they more exactly?

Of course, you’ll eventually find them, but is whatever difficulty you may have encountered necessary?

BeTheme removes that impediment. 

You will notice the Setup Wizard under BeTheme (and in the dashboard as well.) Click on the wizard, and with its step-by-step website, you can: 

  • Give your website a name.
  • Select the page builder you want to work with and choose your preferred editing mode.
  • Pick an ideal pre-built website based on your new website’s industry or niche.
  • Easily replace existing content with your own.

The entire process of loading your brand-new site and page builder into WordPress takes a minute (or more like 30 seconds once you are used to it).

BeTheme

4. Pre-Built Site Previews

With BeTheme, you can choose from more than 650 pre-built websites. New ones are being added as we speak, and they’re delightfully easy to find. Just look under the dashboard’s Websites link or Pre-built Websites in BeTheme’s sidebar menu, and there they are!

You’ll be familiarized with the available design aids and options in no time, and you’ll find it easy to incorporate the latest design trends into your websites. BeTheme has even placed previews of its newest pre-built websites in your dashboard to help you along.

You may choose one of the latest pre-built websites to work with, or you might find one or more others you particularly like. Pre-built sites you do not plan to work with can still be sources of inspiration.

Whatever your choices, you’ll find it easy to incorporate the latest trends into website designs.

BeTheme

5. Plugin Manager

BeTheme’s Plugins area differs from what you see in the WordPress plugins area. You’ll find several of these differences to be particularly helpful in that BeTheme’s plugins manager enables you to: 

  • View the active plugins you’ve installed.
  • Update plugins when necessary.
  • Install and activate plugins only when it’s required.

The last item is essential in that plugins do not appear in the WordPress plugin manager until you have installed them. Not having to install plugins you will not need will help keep your website operating at a high level of performance.

BeTheme

6. BeTheme Support

WordPress is a powerful content management system and an extremely popular one. It may, in fact, be the most powerful and popular system of its type.

WordPress is also community-driven to a considerable extent, which can sometimes create user inconvenience. As a user, you might sometimes have to dig to find answers to your questions or get help when needed.

You don’t have to experience that inconvenience to get support from BeTheme.

To gain access to BeTheme’s support center, you need go no further than BeTheme’s sidebar or dashboard to access self-support options or open a ticket for direct assistance.

BeTheme

7. Theme Options

Plenty of well-known WordPress themes have theme settings customization capabilities. With BeTheme, it’s easy to set brand colors, choose custom fonts, and establish global layouts. The same holds for configuring responsiveness, performance, and accessibility, all of which are essential for optimizing UX and search engine functionalities.

The problem with most theme options is that they can only be modified from the main WordPress dashboard. So if, while designing on a page, you suddenly realize a portion of its design hasn’t been configured correctly, or you’re dissatisfied with any design segment, you’ll have to save your changes and go to your theme’s backend to make the necessary fixes.

From the BeTheme dashboard inside the BeBuilder BeTheme, you can modify your Theme Options without having to interrupt your workflow.

BeTheme

8. White-Label Mode

A final feature of the BeTheme WordPress theme’s backend you should become familiar with is BeCustom. This critical feature is located under BeTheme in the sidebar.

BeCustom enables you to access some white-label regions in BeTheme. 

  You can use BeCustom to:

  • Substitute Be’s branding with your business’s branding to reinforce your name with your clients.
  • Disable any features your clients have no use for and deny access to any features you do not want them to modify while at the same time making the WordPress theme’s backend easier to work with.
  • Create an extra user-friendly and secure WordPress login.
  • Customize the dashboard’s “Welcome” message.

BeTheme

Make Your WordPress Design Projects Simple to Handle With BeTheme

Is there anything BeTheme doesn’t do?

Most likely, but nothing that would adversely impact your design effort.

This multipurpose WordPress theme’s hundreds of pre-built websites will help you get virtually any website project off to a rapid start and headed in the right direction.

The post Why Do WordPress Theme Backends Have to Suck? (Hint: They Don’t!) first appeared on Webdesigner Depot.

Websites haven’t always been as adaptable as they are today. For modern designers, “responsivity” is one of the most significant defining factors of a good design. After all, we’re now catering to a host of users who frequently jump between mobile and desktop devices with varying screen sizes. 

However, the shift to responsive design didn’t happen overnight. For years, we’ve been tweaking the concept of “responsive web design” to eventually reach the stage we’re at today. 

Today, we’re going to take a closer look at the history of responsive web design.

Where Did Web Design Begin?

When the first websites were initially created, no one was worried about responsivity across a range of screens. All sites were designed to fit the same templates, and developers didn’t spend a lot of time on concepts like design, layout, and typography.  

Even when the wider adoption of CSS technology began, most developers didn’t have to worry much about adapting content to different screen sizes. However, they still found a few ways to work with different monitor and browser sizes.

Liquid Layouts

The main two layout options available to developers in the early days were fixed-width, or liquid layout. 

With fixed-width layouts, the design was more likely to break if your monitor wasn’t the exact same resolution as the one the site was designed on. You can see an example here

Alternatively, liquid layouts, coined by Glenn Davis, were considered one of the first revolutionary examples of responsive web design. 

Liquid layouts could adapt to different monitor resolutions and browser sizes. However, content could also overflow, and text would frequently break on smaller screens. 

Resolution-Dependent Layouts

In 2004, a blog post by Cameron Adams introduced a new method of using JavaScript to swap out stylesheets based on a browser window size. This technique became known as “resolution-dependent layouts”. Even though they required more work from developers, resolution-dependent layouts allowed for more fine-grained control over the site’s design. 

The resolution-dependent layout basically functioned as an early version of CSS breakpoints, before they were a thing. The downside was developers had to create different stylesheets for each target resolution and ensure JavaScript worked across all browsers.

With so many browsers to consider at the time, jQuery became increasingly popular as a way to abstract the differences between browser options away.

The Rise of Mobile Subdomains

The introduction of concepts like resolution-dependent designs was happening at about the same time when many mobile devices were becoming more internet-enabled. Companies were creating browsers for their smartphones, and developers suddenly needed to account for these too.

Though mobile subdomains aimed to offer users the exact same functions they’d get from a desktop site on a smartphone, they were entirely separate applications. 

Having a mobile subdomain, though complex, did have some benefits, such as allowing developers to specifically target SEO to mobile devices, and drive more traffic to mobile site variations. However, at the same time, developers then needed to manage two variations of the same website.

Back at the time when Apple had only just introduced its first iPad, countless web designers were still reliant on this old-fashioned and clunky strategy for enabling access to a website on every device. In the late 2000s, developers were often reliant on a number of tricks to make mobile sites more accessible. For instance, even simple layouts used the max-width: 100% trick for flexible images.

Fortunately, everything began to change when Ethan Marcotte coined the term “Responsive Web Design” on A List Apart. This article drew attention to John Allsopp’s exploration of web design architectural principles, and paved the way for all-in-one websites, capable of performing just as well on any device. 

A New Age of Responsive Web Design

Marcotte’s article introduced three crucial components developers would need to consider when creating a responsive website: fluid grids, media queries, and flexible images. 

Fluid Grids

The concept of fluid grids introduced the idea that websites should be able to adopt a variety of flexible columns that grow or shrink depending on the current size of the screen. 

On mobile devices, this meant introducing one or two flexible content columns, while desktop devices could usually show more columns (due to greater space). 

Flexible Images

Flexible images introduced the idea that, like content, images should be able to grow or shrink alongside the fluid grid they’re located in. As mentioned above, previously, developers used something called the “max-width” trick to enable this. 

If you were holding an image in a container, then it could easily overflow, particularly if the container was responsive. However, if you set the “max-width” to 100%, the image just resizes with its parent container. 

Media Queries

The idea of “media queries” referred to the CSS media queries, introduced in 2010 but not widely adopted until officially released as a W3 recommendation 2 years later. Media queries are essentially CSS rules triggered based on options like media type (print, screen, etc), and media features (height, width, etc). 

Though they were simpler at the time, these queries allowed developers to essentially implement a simple kind of breakpoint – the kind of tools used in responsive design today.  Breakpoints refer to when websites change their layout or style based on the browser window or device width.

Viewport Meta tags need to be used in most cases to ensure media queries work in the way today’s developers expect. 

The Rise of Mobile-First Design

Since Marcotte’s introduction of Responsive Web Design, developers have been working on new ways to implement the idea as effectively as possible. Most developers now split into two categories, based on whether they consider the needs of the desktop device user first, or the needs of the mobile device user. The trend is increasingly accelerating towards the latter. 

When designing a website from scratch in an age of mobile-first browsing, most developers believe that mobile-first is the best option. Mobile designs are often much simpler, and more minimalist, which matches a lot of the trends of current web design.

Taking the mobile first route means assessing the needs of the website from a mobile perspective first. You’d write your styles normally, using breakpoints once you start creating desktop and tablet layouts. Alternatively, if you took the desktop-first approach, you would need to constantly adapt it to smaller devices with your breakpoint choices.

Exploring the Future of Responsive Web Design

Responsive web design still isn’t perfect. There are countless sites out there that still fail to deliver the same incredible experience across all devices. What’s more, new challenges continue to emerge all the time, like figuring out how to design for new devices like AR headsets and smartwatches. 

However, it’s fair to say we’ve come a long way since the early days of web design.
