Varnish is a web application accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any Internet site, sometimes even by one hundred percent, depending on the content. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to boost the browsing speed for the site visitors. Whenever a visitor loads a page on a given Internet site, the web browser request is handled by the web server and the requested data is served as a reply. If Varnish is enabled, it caches the pages that the site visitor browses and in case any of them is loaded once more, it’s served by Varnish and not by the server directly. The increase in the performance is due to the fact that the accelerator handles the browser requests substantially faster than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is updated meanwhile, the cached pages will also be ‘refreshed’ the next time somebody opens them.

Varnish in Shared Web Hosting

Varnish is offered as an optional upgrade with all our Linux shared web hosting services. You can add it to your hosting account from the Hepsia Control Panel, which is offered with all shared plans and you will get a rather simple-to-use interface, which will give you full control over the caching system. Using 1-click fast-access controls, you can restart or shut down any of the instances, in other words – Varnish will no longer be activated for a specific site. You can also check a comprehensive system log or erase the cache for any of the sites. When you add Varnish to your web hosting package, you will be able to choose the total amount of system memory that will be available to you for data caching purposes and how many websites will use Varnish. You can always get more memory in increments of 32 MB and, for top performance, you can set a dedicated IP address for the sites that will use Varnish. This will allow you to take full advantage of your sites and to have many happy site visitors.

Varnish in Semi-dedicated Hosting

All our semi-dedicated services include Varnish by default, so you can make full use of the web app accelerator tool and accelerate the speed of any site that you host on our semi-dedicated servers. You will get 64 megabytes of system memory particularly for Varnish at no extra charge and you’ll be able to enable an instance with no more than a couple of clicks through the Hepsia hosting Control Panel, which comes with the semi-dedicated packages. If you want more memory, the latter is available in increments of 32 megabytes through the Upgrades section of the Control Panel and it will be at your disposal instantaneously. You can also order more instances as an upgrade, so you can decide if lots of data will be cached for a single site or whether the available memory will be used by several websites. Hepsia will allow you to restart or to cancel any instance, to check the system log for it or to clear the cached files using one-click controls. To take full advantage of the Varnish accelerator, you can allocate a dedicated IP to the websites which will use it.

Varnish in VPS

You can take full advantage of the workload balancing potential of Varnish with any of our VPS when you pick Hepsia as your web hosting Control Panel. The Varnish platform comes by default and the amount of memory that it’ll be able to use to cache your website content is dependent on the specific package that you have picked, but even with the lower-end plans, 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 improve the overall performance of multiple sites. It will take some time for you to observe the effects, as Varnish caches the content that site visitors open, but soon thereafter you will notice the considerably lowered server load and the enhanced website browsing speed. The Varnish platform will allow you to make use of a less powerful package for Internet sites which would normally require a more expensive hosting solution.

Varnish in Dedicated Hosting

All dedicated hosting that are ordered with the custom-developed Hepsia hosting Control Panel include Varnish, which is one of the pre-installed software platforms that you will get with the dedicated server. The Varnish content caching platform can be set up and administered with ease via the Hepsia Control Panel’s easy-to-navigate interface and, with no more than a click, you can check a detailed log, create or reboot an instance, clear the cached files for any site and much more. Soon after you set up the Varnish platform for a given domain or sub-domain, it will begin caching the pages opened by the website visitors and as soon as it has cached enough content, you’ll perceive a significantly faster website performance in addition to a reduced load on your dedicated machine. With Varnish-dedicated memory starting at three gigabytes, you’ll be able to use the software platform for load distribution purposes even if you run a lot of sites on your machine.
