Varnish is a web app accelerator platform, which caches data for the sake of faster access. It is sometimes called a caching HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor accesses a certain webpage, its content is requested by the Internet browser, and then the server processes this browser request and sends back the necessary info. If Varnish is enabled for a given website, it will cache the pages on the first request and if the visitor accesses a cached page for a second time, the information will be delivered by the accelerator platform and not by the web server. The improved speed is an end result of the much faster response speed that the Varnish platform offers as compared with any server software. Of course, this doesn’t mean that the visitors will continue being served the very same content over and over again, because any modification on any of the web pages is reflected in the content that Varnish saves in its memory.

Varnish in Shared Website Hosting

You can unleash Varnish’s full potential and optimize your websites’ load speed regardless of the shared website hosting plan that you have chosen and you can add and set up the content caching platform with several clicks from the easy-to-use interface offered by our avant-garde Hepsia Control Panel. During the process, you’ll be able to choose two separate things – how many websites will employ the Varnish caching platform, in other words – the number of instances, and how much content will be cached, i.e. the amount of system memory. The latter comes in increments of 32 MB and is not bound to the number of instances, so you can order more instances with less memory and vice versa. If you have plenty of content on a given site and you get numerous website visitors, more system memory will guarantee you a better result. You may also consider employing a dedicated IP for the websites that will use the Varnish caching platform. Hepsia will provide you with simple 1-click controls for deleting or rebooting any instance, for clearing the cache for any site and for checking exhaustive system logs.

Varnish in Semi-dedicated Servers

Varnish is included as standard with all Linux semi-dedicated servers offered by us and you can use it for workload balancing purposes. It’s available in your Hepsia Control Panel. The caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can use it with any Internet site that you host in your semi-dedicated server account. If you are in need of more than that, you can increase the system memory allowance. The memory itself is available in increments of 32 MB through the Control Panel’s Upgrades section. The exact same Upgrades section will allow you to create more instances too, if you’d like to use Varnish with multiple websites. The two upgrades can be ordered independently – you can cache the content of one single large-size site or run several sites with the default memory allowance. You can get the most out of Varnish in case you have a dedicated IP address and you can order one with your semi-dedicated plan as well. Hepsia will grant you total control over the caching platform and, with no more than one click of the mouse, you will be able to delete the cache, to check a log file or to reboot an instance.

Varnish in VPS Servers

You can use Varnish with any of our VPS server packages at no additional charge, since the content caching platform is pre-installed and is available by default. The only precondition is that the virtual machine must be ordered with the Hepsia Control Panel, through which you will be able to set up Varnish for any of your sites with only a couple of clicks. Each VPS package includes a different amount of memory for data caching purposes, but you’ll get minimum several hundred MB, which is sufficient enough even for several resource-requiring sites. Shortly after you activate the Varnish platform, it’ll start caching the content that your visitors browse, so you will notice the significantly better Internet site loading speeds and the lowered load on the server in no time. The Varnish caching platform will permit you to use a less high-priced virtual server, since you will not require that much power to sustain the correct operation of your Internet sites even if you own resource-heavy sites with lots of visitors. Best results are accomplished if the websites which use the Varnish platform use also a dedicated IP.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish content caching platform at no extra fee and you’ll exert total control over it through a truly intuitive interface – you will be able to start, to disable or to restart an instance, to browse a detailed log, to delete the cached files for any site and much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you have frequently visited Internet sites with numerous visitors, you’ll notice the tremendously faster web page loading speeds and the less load on your dedicated machine. This will become a fact shortly after you begin using Varnish, since it will require a certain amount of time to cache the web pages that people open. You can take full advantage of the platform’s capacity in case the Internet sites that are using it use also a dedicated IP address, but owing to the fact that your server comes with a couple of IP addresses by default, you won’t need to pay anything on top of your monthly fee for the server itself.
