Varnish is a data caching platform, which is sometimes referred to as an HTTP reverse proxy. It is a web accelerator tool that can boost the speed of a website by up to one thousand percent, depending on its content. Whenever a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor opens it again. Thus, the browser request from the visitor is not processed by the server and the web page will open significantly faster, as the Varnish caching platform can deliver content many times faster than any server software. The end result is a substantially faster loading page, which leads to a much-improved visitor experience. In case any of the cached web pages is updated on the live website, the info that Varnish keeps in its memory is ‘refreshed’ as well, so the website visitors will not see out-of-date data.

Varnish in Shared Hosting

If you host your Internet sites under a shared hosting account with us, you’ll be able to add Varnish with a couple of clicks through your hosting Control Panel. The data caching platform is available as an optional upgrade with all our hosting plans and you can select how many websites will use it and the maximum storage space that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they aren’t tied directly to each other, so you can choose whether you want lots of memory for one single large-scale site or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish in case the websites use a dedicated IP address. Using the Control Panel, you can quickly start/restart/terminate an instance, delete the cached data independently for each site that employs Varnish or view a detailed log.

Varnish in Semi-dedicated Servers

Varnish is part of the default set of services that you will get when you decide to host your websites in a semi-dedicated server account. You can configure it for any of your Internet sites through our leading-edge Hepsia Control Panel. The default amount of memory that the Varnish platform can use to cache content is 64 MB, but in case you decide that you need more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this platform simultaneously. As these two features aren’t tied to each other, you can use several instances with the default memory or you can order more memory in increments of 32 megabytes and use all of it for one single Internet site. The Varnish platform works best if you allocate a dedicated IP to the websites that utilize its power. Hepsia will offer you an easy means of restarting any instance. Furthermore, you will be able to delete the cached files with just one single click of the mouse.

Varnish in VPS Servers

You can use the workload balancing capabilities of Varnish with all our VPS hosting service when you select Hepsia as your hosting Control Panel. The caching platform is available by default and the amount of system memory that it’ll be able to use to cache your website content is dependent on the particular Virtual Private Server package that you’ve chosen, but even with the less powerful plans, you will have no less than several hundred megabytes of system memory at your disposal exclusively for data caching purposes. This amount is sufficient enough to optimize the performance of numerous sites. It’ll take some time for you to distinguish the results, as the Varnish platform caches the content that site visitors open, but soon thereafter you will notice the significantly reduced load on the virtual machine and the improved Internet site loading speed. The Varnish caching platform will allow you to use a lower-end VPS package for sites which would typically require a more pricey hosting service.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you will get the Varnish data caching platform at no additional charge and you’ll exert full control over it via a rather user-friendly GUI – you will be able to start, to stop or to reboot an instance, to view an exhaustive log, to delete the cached content associated with any Internet site and much, much more. The Varnish platform will have several GB of memory at its disposal, so even if you manage large Internet sites with a vast number of visitors, you’ll notice the much better website loading times and the less load on your dedicated server. This will happen soon after you start using Varnish, as it will require a certain amount of time to cache the site content that people browse. You can get the most out of the platform’s capability if the sites that are using it also use a dedicated IP address, but considering the fact that your dedicated server includes a couple of IPs by default, you won’t have to pay anything on top of your monthly charge for the machine itself.
