Varnish is a website accelerator, which has been gaining a lot of popularity in recent years, as it can increase the speed of any Internet site, sometimes even by 100%, based on the content. This tool is occasionally called an HTTP reverse proxy as well and is used to lower the overall load on the physical server and to enhance the browsing speed for the website visitors. Anytime a visitor opens a page on a specific Internet site, the web browser request is handled by the web server and the requested content is sent as a response. If the Varnish accelerator is enabled, it caches the pages that the site visitor browses and in case any of them is accessed for a second time, it is served by Varnish and not by the server directly. The improvement in the overall performance is due to the fact that the accelerator processes the web requests tremendously faster than any web server, which results in much faster browsing speeds for the users. If any data is updated meanwhile, the cached pages will also be ‘refreshed’ the next time someone attempts to access them.

Varnish in Shared Hosting

If you host your websites in a shared hosting account with us, you will be able to add Varnish with several mouse clicks via your hosting Control Panel. The caching platform comes as an upgrade with all our shared packages and you can select the number of the sites 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 aren’t directly tied to each other, so you can choose if you need lots of memory for one single large-size website or less memory for multiple smaller ones. You can make use of the full potential of the Varnish caching platform if the sites use a dedicated IP. With the hosting Control Panel, you can easily start/restart/cancel an instance, clear the cached data independently for each site which employs the Varnish platform or see a comprehensive log file.

Varnish in Semi-dedicated Servers

Varnish is included in the basic set of services that you’ll receive if you choose to host your Internet sites under a semi-dedicated server account. You can activate it for any of your websites via our leading-edge Hepsia Control Panel. The default system memory that the Varnish platform can use to cache content is 64 megabytes, but in case you decide that you need more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform simultaneously. As these two features are not tied to each other, you can use a few Internet sites with the default memory or you can add more memory in increments of 32 MB and use all of it for one single site. The Varnish platform performs best if you get a dedicated IP for the sites that utilize its power. The Hepsia Control Panel will offer you an easy means of rebooting any instance. Furthermore, you’ll be able to delete the cached content with only one click.

Varnish in VPS Servers

You can take full advantage of the load balancing capabilities of Varnish with each of our VPS servers when you choose Hepsia as your hosting Control Panel. The Varnish platform is available by default and the memory that it will be able to utilize to cache the content of your websites depends on the specific package that you’ve chosen, but even with the lower-end plans, you’ll have no less than several hundred megabytes of memory at your disposal exclusively for content caching purposes. This amount is sufficient enough to optimize the performance of multiple websites. It will take some time for you to observe the effects, since Varnish caches the content that site visitors open, but shortly thereafter you will notice the substantially decreased load on the VPS and the enhanced site load speed. The Varnish caching platform will permit you to use a less powerful VPS plan for Internet sites that would usually need a more expensive web hosting solution.
