Varnish is a web accelerator platform, which caches data for quicker access. It is sometimes called a caching HTTP reverse proxy too and it works between a web server and a web browser. When a site visitor opens a particular web page, its content is requested by the browser, and then the server handles this request and sends back the required information. If Varnish is activated for a certain site, it will cache the pages at the very first visit and if the user opens a cached page again, the info will be delivered by the caching platform and not by the server. The improved load speed is a result of the considerably faster response time that Varnish offers compared with any web server software. At the same time, this doesn’t mean that the visitors will continue being served the very same content again and again, as any modification on any of the web pages is reflected in the content that the Varnish platform keeps in its memory.

Varnish in Shared Website Hosting

Varnish is available as an optional upgrade with all our Linux shared website hosting. You can add it to your hosting account through the Hepsia Control Panel, which comes with all shared hosting plans and you will get a rather simple-to-work-with interface, which will grant you full control over the caching platform. Using 1-click quick-access buttons, you can reboot or stop any of the instances, i.e. Varnish will no longer be enabled for a specific Internet site. You can also check an exhaustive log or erase the cache for any of the websites. When you add Varnish to your shared web hosting plan, you will be able to choose the total amount of system memory that will be at your disposal for caching purposes and how many sites will use Varnish. You can always add more memory in increments of 32 megabytes and, for optimum performance, you can allocate a dedicated IP address to the websites that will use Varnish. This will enable you to take full advantage of your sites and to have plenty of gratified website visitors.

Varnish in Semi-dedicated Hosting

All our Linux semi-dedicated hosting come with Varnish by default, so you can make use of the website accelerator and improve the speed of any website that you host on our platform. You will get 64 megabytes of memory dedicated to Varnish at no additional charge and you can add an instance with no more than a few clicks of the mouse through the Hepsia Control Panel, which comes with the semi-dedicated server plans. If you want more memory, the latter is offered in increments of 32 megabytes in the Upgrades section of the Control Panel and it will be at your disposal momentarily. You can also order more instances as an upgrade, so you can decide whether lots of data will be cached for a single site or if the available memory will be used by multiple sites. Hepsia will enable you to reboot or to shut down any instance, to check the system log associated with it or to delete the cached content using one-click controls. To take full advantage of the Varnish accelerator, you can set a dedicated IP address for the Internet sites which will use it.

Varnish in VPS

You can take advantage of Varnish with all our virtual private server plans at no extra charge, as the data caching platform is pre-installed and is included by default. The only requirement is that the VPS must be ordered with the Hepsia Control Panel, via which you’ll be able to activate Varnish for any of your sites with only a couple of clicks of the mouse. Each VPS plan features a different amount of system memory for data caching purposes, but you’ll get no less than several hundred megabytes, which is quite enough even for multiple resource-hungry websites. Soon after you activate the Varnish platform, it will begin caching the content that your visitors open, so you will notice the substantially faster site loading speeds and the reduced load on your virtual machine in no time. Varnish will permit you to use a less costly virtual server, since you will not need that much power to ensure the correct operation of your Internet sites even if you own large-scale websites with lots of visitors. Optimum results are achieved if the sites which use the Varnish platform also use a dedicated IP address.

Varnish in Dedicated Hosting

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish platform at no additional charge and you will exert full control over it through a quite intuitive GUI – you will be able to start, to delete or to reboot an instance, to browse an in-depth system log, to delete the cached data associated with any website and much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you host resource-swallowing sites with many visitors, you will notice the tremendously faster site load speeds and the lowered load on your dedicated machine. This will become a fact shortly after you start using Varnish, as it will need some time to cache the site content that people browse. You can get the most out of the platform’s capabilities if the Internet sites that are using it also use a dedicated IP address, but due to the fact that your server includes several IPs by default, you won’t need to pay anything on top of the monthly fee for the machine itself.
