Varnish is a website accelerator platform, which caches data for faster access. It’s sometimes referred to as a caching HTTP reverse proxy as well and it works between a web server and its users. When a website visitor loads a specific webpage, its content is requested by the browser, and then the server handles this browser request and sends back the requested content. If Varnish is enabled for a particular site, it will cache the pages at the first visit and in case the user visits a cached page once more, the data will be delivered by the accelerator platform instead of the server. The increased speed is a result of the significantly faster response speed that Varnish offers compared to any web server software. At the same time, this doesn’t mean that the visitors will continue seeing the exact same content again and again, because any update on any of the pages is reflected in the content that Varnish caches in its system memory.

Varnish in Website Hosting

In case you host your sites in a website hosting account with our company, you’ll be able to activate Varnish with a couple of mouse clicks via your hosting Control Panel. The caching platform comes as an optional upgrade with all our web hosting packages and you can select the number of the websites that will use it and the total amount of system memory that will be available for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they’re not linked directly to each other, so you can choose if you want lots of memory for one large-size site or less memory for multiple smaller ones. You can unleash the full potential of the Varnish caching platform if the sites use a dedicated IP address. With the hosting Control Panel, you can swiftly start/reboot/terminate an instance, delete the cached files independently for each site that employs Varnish or see an elaborate log file.

Varnish in Semi-dedicated Hosting

All our Linux semi-dedicated hosting come with Varnish by default, so you can make full use of the web accelerator and increase the load speed of any website that you host on our semi-dedicated servers. You will get 64 megabytes of system memory exclusively for the Varnish accelerator at no additional cost and you’ll be able to activate an instance with no more than a couple of mouse clicks through the Hepsia Control Panel, which is included with the semi-dedicated plans. In case you want more memory, the latter is offered in increments of 32 megabytes in the Control Panel’s Upgrades section and it will be at your disposal straight away. You can also add more instances as a separate upgrade, so you can decide whether lots of content will be cached for a single website or whether the memory will be utilized by multiple sites. Hepsia will enable you to reboot or to discontinue any instance, to check the system log for it or to delete the cached files using one-click controls. To take full advantage of Varnish, you can get a dedicated IP address for the websites that will use it.

Varnish in VPS

You can take full advantage of the workload balancing potential of Varnish with any of our VPS if you pick Hepsia as your Control Panel. The content caching platform is available by default and the amount of memory that it will be able to utilize to cache the content of your websites depends upon the specific Virtual Private Server package that you have selected, but even with the lower-end plans, you’ll have no less than several hundred MB of system memory at your disposal only for caching purposes. This amount is sufficient enough to improve the performance of multiple websites. It will take a little time for you to distinguish the effects, since Varnish caches the content that website visitors browse, but shortly after that you’ll notice the considerably lowered load on the server and the improved website browsing speed. Varnish will permit you to use a lower-end VPS plan for sites that would usually require a more high-priced web hosting solution.

Varnish in Dedicated Hosting

All dedicated hosting that are ordered with the in-house built Hepsia web hosting Control Panel feature Varnish, which is one of the pre-installed platforms that you’ll get with the dedicated machine. The Varnish data caching platform can be enabled and managed with ease from the Hepsia Control Panel’s simple-to-work-with interface and, with no more than a click, you can check an in-depth log, create or reboot an instance, clear the cached data for any site and much, much more. Soon after you configure the Varnish platform for a certain domain or sub-domain, it will begin caching the webpages browsed by the visitors and as soon as it has cached enough content, you will perceive a substantially better site performance as well as a lowered load on the dedicated machine. With Varnish-dedicated memory starting at 3 GB, you’ll be able to use the platform for workload distribution purposes even if you host plenty of sites on your dedicated machine.
