FAQ

Varnish Cache is an open source HTTP reverse proxy developed to accelerate the performance of web applications. It acts as an intermediary between the web server and clients, storing copies of requested web pages and then serving them to subsequent visitors more quickly. This reduces the load on the web server and increases page loading speed. Varnish is known for its high flexibility and can be customized for a wide range of needs, from advanced cache management to HTTP traffic optimization. It is an ideal solution for websites with high traffic and high performance requirements.

Varnish is a web application accelerator, also known as reverse proxy cache, that can significantly speed up a website by reducing the load on the web server. It works by caching static versions of web pages, allowing sites to serve these pages faster to users without having to generate the page each time through the slower process of running server-side scripts. This means faster page load times, which is a significant benefit to user experience and can help improve SEO. Additionally, by reducing the load on web servers, Varnish can help reduce operational costs and resource usage, improve scalability during traffic spikes, and increase website resilience against unexpected traffic spikes or DDoS attacks. Varnish is highly customizable and can be configured for a variety of caching scenarios, making it a powerful tool for optimizing the performance of dynamic websites.

We offer a complete package of Varnish Cache services that includes the creation of custom configurations designed to meet your specific needs for advanced caching and traffic optimization. We take care of the planning and implementation of Varnish Cache in your IT environment, and offer assistance with migration from other caching systems. Our technical support is designed to ensure optimal operation, with updates and resolution of any problems. We work with you to integrate Varnish Cache with other system components, such as web servers, databases and CMS. We will conduct performance analyzes to evaluate the impact of Varnish Cache and propose targeted improvements, ensuring through constant monitoring that the solution is always optimally configured. We also perform security audits to ensure your setup is secure and in line with industry best practices.

Figuring out whether you need Varnish support depends on various factors, including the specific needs of your web project, in-house technical expertise, and performance goals. However, it is important to note that Varnish is applicable to a wide range of online platforms: from services to blogs, through e-commerce, information portals and online newspapers.

  1. Technical Complexity: If your site has a complex structure or uses advanced technologies, professional assistance can be crucial to implementing Varnish effectively.

  2. High Traffic: If your website or application has a high volume of traffic, a support service can help you manage performance and scalability more effectively.

  3. Lack of Internal Experts: If you don't have an internal team with specific Varnish expertise, a support service can fill this gap.

  4. Continuous Optimization: Even if you already have Varnish installed, a support service can provide ongoing optimization and advice on how to adapt the configuration to changing needs.

  5. Security and Compliance: To ensure your Varnish installation is safe and compliant with best practices, a professional service can perform audits and provide recommendations.

Given its near-universal applicability, it would be intuitive and logical that almost any type of online platform could benefit from implementing Varnish. If you do not currently have Varnish installed, considering support may be a step towards an improved user experience and optimized performance.

Certainly, Varnish Cache is compatible and can be implemented to significantly improve the performance of sites built on CMS such as WordPress, Joomla, Drupal, Magento and PrestaShop. Our team of experts is able to customize Varnish Cache configurations, creating VCL (Varnish Configuration Language) rules tailored to each specific CMS. This allows you to optimize caching and effectively manage traffic, which translates into an improved user experience thanks to reduced loading times and smoother navigation on the site.

An optimized Varnish Cache setup also contributes to SEO, as search engines tend to reward websites that load quickly and offer a good user experience. Varnish helps reduce server response time and speed up content display, which are especially important for metrics like Largest Contentful Paint (LCP), one of the Core Web Vitals of Google.

Each CMS has its own specifics in terms of cache management; for example, WordPress has different types of plugins and themes that may require special caching rules, while Magento may have different types of dynamic content that need different treatment. We customize Varnish VCLs for each CMS to ensure that caching is effective and dynamic pages are handled correctly, without compromising functionality or content freshness.

Our goal is to ensure that your online presence is fast, reliable and optimized not only for users but also for search engine ranking criteria, ensuring that your website can get the visibility it deserves.

Yes, Varnish Cache can also be used effectively with websites and custom applications built using a wide range of programming technologies and frameworks such as Python, Java, Go, Node.js or PHP-based frameworks. Our experience is not limited to implementing Varnish Cache at the infrastructure level, but also includes working closely with the developers on your team to refine the application's business logic so that it works harmoniously with Varnish.

Let's tackle the Varnish integration process in the round, working on both the caching system configuration and the application code. We create specific routines and write custom code to ensure that caching rules reflect the business logic of your site or application. This means that caching behavior can be adapted and optimized to handle user sessions, authentication, dynamic and transactional content that are typical of applications built with languages ​​such as Python or Java, or sites based on Node.js or Go.

Code customization could include developing middleware, hooks, or filters that interact with Varnish to intelligently handle cache invalidation, ensuring that updated data is served to users when needed, while static, less frequent content can be served by cache to reduce server load and improve response speed.

For each specific framework or technology, we consider best practices for integrating with Varnish. For example, in a Node.js application, we can implement a middleware layer to interface Varnish with the application, while for a Python application, we could integrate Varnish with WSGI or work together with frameworks like Django or Flask to optimize caching .

Our collaboration extends beyond the initial setup, providing ongoing optimization and technical support to ensure your application remains fast, scalable and secure over time, with Varnish as a key component in your custom site's caching and performance strategy .

First and foremost, Varnish requires a compatible operating system to function optimally. It is designed to run on various Unix-based operating systems, including Linux and FreeBSD. These systems provide a set of tools and features that Varnish can use to best express its performance. Your choice of operating system may depend on various factors, such as your familiarity with it, the hardware resources available, and the specific needs of your website or application.

Another fundamental prerequisite for using Varnish is a stable and reliable Internet connection. Varnish acts as an HTTP reverse proxy, thus handling requests to and from the web. A solid Internet connection is therefore essential to ensure that Varnish can interact effectively with web clients and servers.

Last but not least, installing and configuring Varnish requires some technical expertise. You must have a good understanding of Unix-based operating systems and the ability to execute commands from a shell. Setting up Varnish can be a complicated process that requires detailed knowledge of networks, HTTP protocols, and server performance. If these aspects seem difficult to you, you may consider the option of hiring a professional or using a specialized support service to help you install and configure Varnish.

Of course, Varnish is designed to be extremely flexible and therefore can be used with a variety of web servers, such as NGINX, Apache and IIS. When you integrate Varnish with a web server, it acts as an intermediary between the server and clients making requests to the website. This allows Varnish to cache server responses, so that subsequent requests for the same resources can be served more quickly, directly from Varnish's cache.

In the case of NGINX or Apache, which are especially popular on Linux platforms, integration is often considered easier due to extensive documentation and active developer communities. For example, you can use NGINX for SSL termination, while Varnish manages HTTP caching, providing a complete and performant system.

With IIS, which is a web server from Microsoft, integration can be a little more complex due to differences in operating system architectures. However, even in this scenario, it is entirely possible to make Varnish work with IIS to improve website performance and efficiency.

Each web server has its own specifics, so configuring Varnish may require unique steps for each case. But overall, Varnish's adaptability makes it a great addition to any web server, helping optimize performance and improve user experience.
