Varnish is a web accelerator platform, which caches data for faster access. It’s sometimes referred to as an HTTP reverse proxy as well and it works between a web server and a browser. When a website visitor opens a specific webpage, its content is requested by the browser, and then the server handles this browser request and sends back the required information. If Varnish is enabled for a specific website, it will cache its pages at the first visit and in case the visitor opens a cached page once again, the info will be delivered by the accelerator platform and not by the web server. The boosted speed is an end result of the considerably faster response time that the Varnish platform offers as compared to any web server software. Of course, this does not mean that the users will continue seeing the exact same content over and over again, since any change on any of the pages is reflected in the content that Varnish stores in its memory.

Varnish in Shared Hosting

Varnish is available as an optional upgrade with each of our Linux shared hosting. You can add it to your hosting account from the Hepsia Control Panel, which comes with all shared plans and you will get a really easy-to-work-with GUI, which will grant you complete control over the data caching platform. Using 1-click quick-access buttons, you can restart or delete any of the instances, in other words – Varnish will no longer be activated for a given site. You can also check a comprehensive log file or erase the cache associated with any of the sites. When you add Varnish to your shared hosting plan, you will be able to select the maximum amount of system memory that will be available to you for content caching purposes and how many websites will use Varnish. You can always add more memory in increments of 32 MB and, for maximum performance, you can assign a dedicated IP to the websites that will use Varnish. This will enable you to get the most out of your sites and to have a lot of happy site users.

Varnish in Semi-dedicated Servers

All our Linux semi-dedicated servers come with Varnish by default, so you can take advantage of the web accelerator and speed up any website that you host on our platform. You’ll get 64 MB of memory exclusively for Varnish at no additional cost and you’ll be able to create an instance with no more than a few mouse clicks via the Hepsia Control Panel, which comes with the semi-dedicated packages. In case you want more memory, the latter is offered in increments of 32 megabytes through the Upgrades section of the Control Panel and it will be available to you immediately. You can also add more instances as a separate upgrade, so you can choose whether lots of content will be cached for one website or whether the memory will be utilized by different sites. Hepsia will permit you to restart or to stop any instance, to see the system log file associated with it or to delete the cached files using single-click controls. To take full advantage of the Varnish accelerator, you can get a dedicated IP address for the Internet sites which will use it.

Varnish in VPS Servers

You can take full advantage of the load balancing potential of Varnish with each of our Linux VPS hosting plans when you choose Hepsia as your web hosting Control Panel. The Varnish data caching platform is available by default and the amount of system memory that it’ll be able to utilize to cache the content of your websites depends on the given VPS package that you’ve selected, but even with the less powerful plans, you’ll have no less than several hundred MB of system memory at your disposal exclusively for caching purposes. This amount is enough to enhance the overall performance of multiple Internet sites. It will take some time for you to distinguish the results, since Varnish caches the content that visitors open, but shortly after that you’ll notice the substantially decreased load on the VPS server and the enhanced Internet site loading speed. Varnish will allow you to use a lower-end VPS package for websites which would typically need a more pricey hosting service.

Varnish in Dedicated Servers

All dedicated servers which are ordered with the in-house built Hepsia website hosting Control Panel come with Varnish, which is one of the pre-installed platforms that you’ll get with the dedicated machine. The Varnish content caching platform can be configured and managed effortlessly through Hepsia’s time and effort saving interface and, with no more than one mouse click, you can see an in-depth system log, create or reboot an instance, delete the cache for any Internet site and much, much more. Soon after you configure Varnish for a particular domain or subdomain, it will begin caching the webpages loaded by the visitors and as soon as it has cached enough content, you’ll perceive a substantially better site performance as well as a decreased load on your dedicated machine. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the software platform for workload balancing purposes even if you run a huge number of sites on your server.
