Varnish is a web accelerator platform, which caches info for quicker access. It’s occasionally called an HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a visitor loads a given web page, the content is requested by the Internet browser, and then the web server processes this browser request and sends back the required info. If Varnish is enabled for a specific website, it will cache its pages on the first request and in case the user opens a cached page once more, the information will be delivered by the accelerator platform instead of the web server. The increased load speed is a result of the considerably faster response speed that the Varnish platform offers as compared to any web server software. Of course, this does not mean that the site visitors will continue seeing the exact same content over and over again, as any modification on any of the web pages is reflected in the content that the Varnish platform stores in its system memory.

Varnish in Shared Hosting

In case you host your Internet sites under a shared hosting account with us, you’ll be able to activate Varnish with a couple of clicks through your hosting Control Panel. The caching platform comes as an optional upgrade with all our shared plans and you can select the number of the websites that will use it and the total storage space that will be available for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they are not linked directly to each other, so you can decide whether you need plenty of memory for a single large-size website or less memory for several smaller ones. You can take advantage of the full potential of the Varnish platform in case the websites use a dedicated IP address. Using the Control Panel, you can swiftly start/restart/terminate an instance, clear the cached contents individually for each site which uses Varnish or check an exhaustive log file.

Varnish in Semi-dedicated Servers

The Varnish platform is part of the default service set that you’ll get in case you decide to host your sites under a semi-dedicated server account. You can activate it for any of your websites through our avant-garde Hepsia Control Panel. The default memory that the Varnish caching platform can use to cache data is 64 megabytes, but in case you decide that you want more, you can upgrade this amount of memory 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 at the same time. As these two features aren’t linked to each other, you can use a few websites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for one single web site. Varnish works best if you allocate a dedicated IP to the websites that utilize its power. The Hepsia Control Panel will provide you with a simple means of rebooting any instance. What’s more, you’ll be able to clear the cached contents with just one click.

Varnish in VPS Servers

You can take advantage of Varnish with any of our VPS server packages at no additional fee, as the platform is pre-installed and is included by default. The one and only requirement is that the VPS server must be ordered with the Hepsia Control Panel, via which you’ll be able to set up Varnish for any of your sites with only a few mouse clicks. Each plan offers a different amount of system memory for content caching purposes, but you will get minimum several hundred MB, which is quite sufficient even for several regularly visited Internet sites. Shortly after you activate Varnish, it will start caching the content that your visitors access, so you will notice the significantly better web page loading speeds and the decreased load on the virtual machine in no time. The caching platform will allow you to use a less expensive virtual machine, as you will not require that much power to guarantee the uninterrupted operation of your sites even if you own traffic-heavy websites with many visitors. Maximum results are achieved if the Internet sites that use the Varnish caching platform also use a dedicated IP.

Varnish in Dedicated Servers

All Linux dedicated service which are ordered with the tailor-made Hepsia hosting Control Panel come with Varnish, which is one of the pre-installed platforms that you’ll get with the dedicated machine. The Varnish data caching platform can be set up and managed without any effort via Hepsia’s user-friendly interface and, with no more than one click of the mouse, you can see an exhaustive system log, create or reboot an instance, clear the cache associated with any site and much more. Soon after you configure the Varnish platform for a given domain or sub-domain, it will start caching the webpages accessed by the site visitors and once it has cached enough content, you’ll observe a tremendously better site performance plus a reduced load on your dedicated server. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the software platform for load balancing purposes even if you run lots of sites on the machine.
