Varnish is a web application accelerator platform, which caches content for faster response times. It is occasionally called an HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor loads a given web page, the content is requested by the web browser, and then the web server processes this browser request and delivers the needed data. If Varnish is activated for a certain site, it will cache its pages on the very first request and in case the visitor opens a cached page again, the data will be delivered by the accelerator platform and not by the server. The improved speed is a result of the much faster response time that the Varnish platform offers compared with any server software. At the same time, this does not mean that the website visitors will keep being served the exact same content again and again, since any modification on any of the pages is reflected in the content that the Varnish platform keeps in its memory.

Varnish in Cloud Website Hosting

If you host your websites in a cloud website hosting account with us, you’ll be able to add Varnish with a couple of mouse clicks through your Control Panel. The content 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 features that can be upgraded in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t linked directly to each other, so you can decide if you need a lot of memory for one single large-size website or less memory for several smaller ones. You can make use of the full potential of Varnish in case the sites use a dedicated IP. With the hosting Control Panel, you can quickly start/reboot/delete an instance, clear the cached data independently for each site which uses Varnish or view an elaborate log.

Varnish in Semi-dedicated Hosting

All our semi-dedicated hosting include Varnish by default, so you can make full use of the website accelerator tool and increase the speed of any site that you host on our semi-dedicated servers. You will get 64 MB of memory exclusively for Varnish at no additional cost and you can add an instance with no more than a couple of mouse clicks via the Hepsia Control Panel, which is included with the semi-dedicated plans. If you need more memory, the latter is available in increments of 32 megabytes in the Upgrades section of the Control Panel and it will be available to you instantly. You can also add more instances as a separate upgrade, so you can decide if lots of content will be cached for one website or if the available memory will be utilized by several sites. Hepsia will allow you to restart or to shut down any instance, to view the system log associated with it or to clear the cached data using one-click controls. To take full advantage of the Varnish accelerator, you can assign a dedicated IP to the sites which will employ it.

Varnish in VPS Hosting

You can use the load balancing capabilities of Varnish with each of our Linux VPS hosting when you pick Hepsia as your hosting Control Panel. The data caching platform is available by default and the amount of memory that it’ll be able to utilize to cache your site content is dependent upon the given Virtual Private Server plan that you have chosen, but even with the less powerful packages, you will have at least several hundred MB of memory at your disposal exclusively for data caching purposes. This amount is enough to boost the work of numerous sites. It’ll take a little time for you to observe the effects, as the Varnish platform caches the content that site visitors request, but after that you’ll notice the considerably lowered server load and the improved Internet site load speed. The Varnish caching platform will permit you to use a less powerful Virtual Private Server plan for Internet sites that would usually require a more pricey web hosting solution.

Varnish in Dedicated Web Hosting

If you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish platform at no extra charge and you will exert complete control over it through an amazingly user-friendly graphical interface – you’ll be able to start, to terminate or to reboot an instance, to check an exhaustive log, to delete the cached data associated with any website and much, much more. Varnish will have several GB of virtual memory at its disposal, so even if you have heavy sites with lots of visitors, you will notice the significantly faster site load speeds and the reduced server load. This will happen soon after you begin using Varnish, as it will require some time to cache the pages that visitors browse. You can take full advantage of the platform’s capabilities in case the websites that are using it use also a dedicated IP address, but considering the fact that your server includes several IPs by default, you will not have to pay anything on top of the monthly fee for the machine itself.
