Varnish is a web accelerator platform, which caches information for the sake of quicker response times. It is occasionally called a caching HTTP reverse proxy too and it interacts between a web server and a web browser. When a site visitor opens a given webpage, its content is requested by the browser, and then the server processes this browser request and returns the necessary information. If Varnish is activated for a certain website, it will cache the pages at the first request and if the visitor opens a cached page once more, the data will be delivered by the caching platform instead of the web server. The boosted speed is an end result of the substantially faster response speed that Varnish offers as compared with any server software. At the same time, this does not mean that the users will keep being served the very same content again and again, as any modification on any of the web pages is reflected in the content that the Varnish platform saves in its system memory.

Varnish in Shared Web Hosting

In case you host your websites in a shared web hosting account with our company, you will be able to add Varnish with a couple of mouse clicks from your Control Panel. The data caching platform comes as an upgrade with all our web hosting plans and you can select the number of the websites that will use it and the total amount of system memory that will be available for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they’re not linked directly to each other, so you can choose if you need a lot of memory for one single large-scale website or less memory for multiple smaller ones. You can make use of the full potential of the Varnish platform if the sites use a dedicated IP. With the hosting Control Panel, you can effortlessly start/restart/delete an instance, delete the cached content individually for each site that employs the Varnish platform or see an in-depth log.

Varnish in Semi-dedicated Hosting

The Varnish caching platform is included in the default service set that you’ll obtain in case you decide to host your websites in a semi-dedicated server account. You can activate it for any of your websites through our next-generation Hepsia hosting Control Panel. The default system memory that the Varnish platform can use to cache data is 64 megabytes, but if you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform simultaneously. As these two things are not linked to each other, you can use several sites with the default memory or you can order more memory in increments of 32 megabytes and use all of it for a single website. The Varnish platform works best when you get a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will provide you with a simple means of rebooting any instance. In addition, you will be able to clear the cached content with just one single mouse click.

Varnish in VPS Web Hosting

The Varnish caching platform is included by default with all Linux VPS web hosting packages offered by our company on the condition that the Virtual Private Server is ordered with the Hepsia Control Panel, so you can boost the work of your websites with only a few mouse clicks. The more powerful the package, the more system memory Varnish will have at its disposal, but even with a low-end package, the caching platform will be able to utilize several hundred megabytes, so even if you run several Internet sites, you will notice a considerable decrease in the overall server load and a significantly better website loading speed. The platform will have to work for a little while while the visitors navigate the website and once the site content has been cached, you’ll perceive the effect. One of the pros of using Varnish is that a less powerful and less high-priced package will accomplish the exact same job as a more expensive one without the platform, so not only will your sites work significantly better, but you’ll also save some money.
