Varnish is a web accelerator, which has been gaining a lot of popularity lately, because it can increase the speed of any website, at times even by 100 percent, depending on the content. This tool is sometimes referred to as a caching HTTP reverse proxy too and is used to lower the overall load on the physical server and to accelerate the browsing speed for the website visitors. Every time a visitor loads a page on a certain site, the browser request is taken care of by the web server and the requested content is sent as a reply. If Varnish is enabled, it caches the web pages that the website visitor browses and in case any of them is loaded once more, it is served by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator processes the browser requests significantly faster than any web server, which results in much faster browsing speeds for the users. If any content is updated in the meantime, the cached pages will also be updated the next time someone attempts to open them.

Varnish in Shared Website Hosting

In case you host your sites under a shared website hosting account with us, you will be able to add Varnish with several clicks of the mouse from your Control Panel. The data caching platform is available as an upgrade with all our web hosting plans and you can select how many sites will use it and the maximum storage space that will be available for the cached data. The two upgradeable features 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 decide if you need lots of memory for one single large site or less memory for several smaller ones. You can use the full potential of the Varnish caching platform in case the sites use a dedicated IP. Using the hosting Control Panel, you can swiftly start/reboot/deactivate an instance, clear the cached contents individually for each website which employs the Varnish platform or check an in-depth log.

Varnish in Semi-dedicated Servers

Varnish comes as standard with all semi-dedicated plans that we offer and you can use it for load balancing purposes. It is available in your Hepsia Control Panel. The Varnish caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any site that you host in your account. If you need more, you can increase the memory allocation. The memory itself is offered in increments of 32 megabytes through the Control Panel’s Upgrades section. The very same Upgrades section will allow you to enable more instances too, in case you would like to use the Varnish platform with multiple websites. The two upgrades can be added separately – you can cache the content of one single large-sized site or use a number of sites with the default memory quota. You can take full advantage of the Varnish platform in case you have a dedicated IP and you can get one with your semi-dedicated server package as well. Hepsia will grant you full control over the caching platform and, with no more than one single mouse click, you will be able to delete the cached contents, to check a system log file or to restart an instance.

Varnish in Dedicated Servers

All dedicated web hosting plans which are ordered with the tailor-made Hepsia hosting Control Panel include Varnish, which is among the pre-installed platforms that you’ll get with the server. The Varnish content caching platform can be configured and administered with no effort through Hepsia’s simple-to-work-with interface and, with no more than one click of the mouse, you can check a detailed system log, add or restart an instance, clear the cached data for any website and much more. Soon after you configure the Varnish platform for a certain domain or subdomain, it will begin caching the pages requested by the website visitors and as soon as it has cached enough web content, you will observe a considerably faster site performance as well as a lowered load on your dedicated server. With Varnish-dedicated virtual memory starting at 3 gigabytes, you will be able to use the software platform for workload distribution purposes even if you run a lot of Internet sites on the dedicated server.
