Varnish is a web application accelerator platform, which caches content for the sake of quicker response times. It is occasionally called an HTTP reverse proxy as well and it works between a web server and a web browser. When a website visitor opens a given page, its content is requested by the web browser, and then the web server handles this request and delivers the necessary information. If Varnish is enabled for a particular website, it will cache the pages on the very first visit and in case the user accesses a cached page for a second time, the information will be delivered by the caching platform instead of the web server. The boosted speed is a result of the substantially faster response speed that Varnish offers as compared to any web server software. At the same time, this doesn’t mean that the website visitors will continue seeing the exact same content over and over again, since any modification on any of the web pages is reflected in the content that the Varnish platform saves in its memory.

Varnish in Shared Hosting

In case you host your sites under a shared hosting account with us, you will be able to add Varnish with a couple of clicks of the mouse via your Control Panel. The platform comes as an upgrade with all our shared hosting plans and you can choose the number of the sites 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’re not directly tied to each other, so you can decide if you need lots of memory for one single large site or less memory for several smaller ones. You can unlock the full potential of the Varnish caching platform if the websites use a dedicated IP. Using the hosting Control Panel, you can quickly start/restart/cancel an instance, clear the cached data independently for each website that uses Varnish or view a comprehensive log file.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is included in the basic service set that you will receive in case you decide to host your Internet sites in a semi-dedicated server account. You can activate it for any of your websites through our innovative Hepsia Control Panel. The default memory that the Varnish platform can use to cache content is 64 MB, but if you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this caching platform at the same time. Since these two features are not bound to each other, you can use a couple of instances with the default memory or you can add more memory in increments of 32 MB and use all of it for a single site. The Varnish platform works best if you set a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will provide you with a simple means of restarting any instance. What’s more, you will be able to clear the cached files with only one click of the mouse.

Varnish in VPS Servers

You can take full advantage of the workload balancing capabilities of Varnish with all our VPS servers when you choose Hepsia as your web hosting Control Panel. The Varnish platform comes by default and the memory that it’ll be able to use to cache your website content is dependent on the particular VPS package that you have chosen, but even with the lower-end packages, you’ll have no less than several hundred MB of system memory at your disposal exclusively for caching purposes. This amount is sufficient to improve the overall performance of numerous Internet sites. It will take some time for you to detect the results, as Varnish caches the content that website visitors open, but soon after that you will notice the substantially less load on the VPS server and the enhanced website browsing speed. Varnish will permit you to use a less powerful Virtual Private Server plan for sites that would usually need a more high-priced hosting service.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish platform at no extra fee and you’ll exert full control over it through an amazingly simple-to-use GUI – you will be able to start, to disable or to reboot an instance, to check an exhaustive system log, to delete the cache associated with any website and much more. The Varnish caching platform will have several gigabytes of virtual memory at its disposal, so even if you have heavy sites with plenty of visitors, you will notice the much faster website loading speeds and the decreased load on the machine. This will become a fact soon after you start using Varnish, since it will require some time to cache the content that visitors access. You can take full advantage of the platform’s capability if the Internet sites that are using it also use a dedicated IP, but considering the fact that your dedicated server comes with several IPs by default, you will not have to pay anything on top of your monthly fee for the machine itself.
