Varnish is a web application accelerator platform, which caches content for the sake of faster response times. It is occasionally called a caching HTTP reverse proxy as well and it interacts between a web server and a web browser. When a website visitor opens a particular web page, the content is requested by the web 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 on the very first request and in case the user visits a cached page for a second time, the info will be delivered by the caching platform and not by the server. The increased speed is an end result of the substantially faster response time that the Varnish platform offers compared to any server software. At the same time, this doesn’t mean that the site visitors will continue seeing the same content over and over again, as any modification on any of the pages is reflected in the content that the Varnish platform stores in its system memory.

Varnish in Cloud Hosting

In case you host your Internet sites in a cloud hosting account with us, you will be able to activate Varnish with a couple of clicks of the mouse through your hosting Control Panel. The caching platform comes as an upgrade with all our shared hosting packages and you can select the number of the sites that will use it and the maximum amount of system memory that will be available for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they are not tied directly to each other, so you can choose if you want lots of memory for one large site or less memory for multiple smaller ones. You can unleash the full potential of Varnish in case the websites use a dedicated IP address. With the hosting Control Panel, you can easily start/restart/cancel an instance, delete the cached contents independently for each site which employs the Varnish platform or view an in-depth system log file.

Varnish in Semi-dedicated Hosting

The Varnish caching platform is an essential part of the basic service set that you will receive if you decide to host your websites in a semi-dedicated server account. You can set it up for any of your websites via our innovative Hepsia Control Panel. The default system memory that Varnish can use to cache data is 64 MB, but in case 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, in other words – the number of the Internet sites that can use this caching platform at the same time. As these two features aren’t linked to each other, you can use a couple of instances with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for one single website. The Varnish caching platform works best when you use a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will offer you a simple way of restarting any instance. What’s more, you’ll be able to clear the cached files with just one click.

Varnish in VPS Hosting

You can use the load balancing potential of Varnish with all our Linux VPS hosting packages if you choose Hepsia as your Control Panel. The Varnish caching platform comes by default and the memory that it’ll be able to use to cache your website content is dependent upon the given VPS package that you’ve picked, but even with the less powerful packages, you will have no less than several hundred MB of system memory at your disposal only for content caching purposes. This amount is enough to enhance the performance of numerous sites. It’ll take a little time for you to notice the results, since Varnish caches the content that website visitors open, but after that you will notice the significantly less load on the VPS and the increased Internet site browsing speed. The Varnish platform will allow you to make use of a less powerful plan for websites that would normally need a more high-priced hosting solution.

Varnish in Dedicated Web Hosting

All Linux dedicated servers hosting packages that are ordered with the in-house developed Hepsia hosting Control Panel include Varnish, which is one of the pre-installed platforms that you will get with the dedicated machine. The Varnish content caching platform can be activated and administered with ease through the Hepsia Control Panel’s easy-to-navigate graphical interface and, with no more than one single click, you can browse an in-depth log, add or reboot an instance, clear the cached files associated with any site and much more. Soon after you activate Varnish for a particular domain or sub-domain, it will begin caching the pages browsed by your site visitors and as soon as it has cached enough web content, you’ll observe a tremendously faster website performance and a reduced load on your server. With Varnish-dedicated virtual memory starting at 3 GB, you’ll be able to use the platform for workload balancing purposes even if you run plenty of sites on the dedicated server.
