Varnish is a website accelerator platform, which caches information for faster access. It is sometimes called an HTTP reverse proxy too and it interacts between a web server and a browser. When a visitor loads a specific page, the content is requested by the web browser, and then the server processes this browser request and delivers the necessary data. If Varnish is enabled for a website, it will cache the pages on the first visit and if the visitor visits a cached page for a second time, the content will be delivered by the accelerator platform and not by the web server. The increased speed is a result of the much faster response speed that the Varnish platform offers as compared with any server software. At the same time, this doesn’t mean that the site visitors will continue seeing the exact same content again and again, as any modification on any of the web pages is reflected in the content that Varnish stores in its system memory.

Varnish in Cloud Hosting

Varnish is available as an optional upgrade with all our Linux cloud hosting service. You can add it to your web hosting account via the Hepsia Control Panel, which is offered with all shared hosting plans and you’ll get a very user-friendly graphical interface, which will grant you complete control over the content caching platform. Using one-click quick-access controls, you can reboot or discontinue any of the instances, i.e. Varnish will no longer be activated for a specific site. You can also see an in-depth log or erase the cache for any of the Internet sites. When you add Varnish to your shared web hosting plan, you will be able to choose the total amount of system memory that will be at your disposal for caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimal performance, you can get a dedicated IP for the sites that will use Varnish. This will allow you to take full advantage of your sites and to have numerous gratified website visitors.

Varnish in Semi-dedicated Servers

Varnish is part of the default set of services that you’ll obtain in case you choose to host your Internet sites under a semi-dedicated server account. You can enable it for any of your websites through our avant-garde Hepsia hosting Control Panel. The default system memory that the Varnish platform can use to cache data is 64 megabytes, 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, i.e. the number of the Internet sites that can use this platform at the same time. Since these two features aren’t linked to each other, you can use a couple of websites with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for one single site. The Varnish platform works best if you assign a dedicated IP address to the sites that utilize its power. The Hepsia Control Panel will give you an easy means of restarting any instance. Also, you’ll be able to clear the cached files with just one click.

Varnish in VPS Servers

You can use the load balancing potential of Varnish with any of our Linux VPS servers in case you select Hepsia as your Control Panel. The Varnish platform comes by default and the system memory that it will be able to use to cache your website content depends upon the particular Virtual Private Server plan that you have selected, but even with the lower-end packages, you’ll have no less than several hundred MB of memory at your disposal exclusively for content caching purposes. This amount is enough to improve the overall performance of multiple Internet sites. It will take some time for you to observe the effects, as the Varnish platform caches the content that visitors open, but soon after that you’ll notice the substantially decreased load on your virtual machine and the enhanced site browsing speed. The Varnish platform will permit you to make use of a less powerful Virtual Private Server plan for websites that would normally require a more expensive hosting solution.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you’ll obtain the Varnish caching platform at no additional charge and you’ll exert complete control over it through a very time and effort saving interface – you will be able to start, to deactivate or to reboot an instance, to browse a comprehensive log, to clear the cached files for any Internet site and much more. The Varnish platform will have several GB of virtual memory at its disposal, so even if you manage resource-heavy Internet sites with a lot of visitors, you will notice the tremendously faster page load times and the lowered load on the server. This will happen soon after you begin using the Varnish platform, as it will need a certain amount of time to cache the web pages that people request. You can take full advantage of the platform’s capacity in case the Internet sites that are using it also use a dedicated IP, but owing to the fact that your server includes a few IPs by default, you won’t have to pay anything on top of the monthly charge for the server itself.
