Varnish is a web accelerator tool, which has been gaining a lot of popularity lately, as it can increase the loading speed of any website, sometimes even by 100 percent, based on the content itself. This tool is sometimes called an HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to improve the browsing speed for the site visitors. Whenever a visitor loads a page on a given site, the web browser request is processed by the web server and the requested data is served as a response. If Varnish is activated, it caches the pages that the site visitor browses and if any of them is loaded once again, it’s served by Varnish and not by the web server directly. The performance increase is due to the fact that the accelerator handles the web requests tremendously quicker than any web server, which results in much faster browsing speeds for the users. In case any data is modified meanwhile, the cached pages will also be ‘refreshed’ the next time someone opens them.

Varnish in Hosting

In case you host your websites under a hosting account with us, you’ll be able to activate Varnish with a few mouse clicks through your Control Panel. The data caching platform is offered as an optional upgrade with all our plans and you can choose the number of the websites that will use it and the maximum storage space that will be used for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they aren’t directly tied to each other, so you can decide whether you want plenty of memory for a single large-size site or less memory for several smaller ones. You can unleash the full potential of the Varnish platform in case the websites use a dedicated IP address. With the Control Panel, you can swiftly start/restart/discontinue an instance, delete the cached contents independently for each site which uses the Varnish platform or see an elaborate log.

Varnish in Semi-dedicated Servers

All our semi-dedicated servers include Varnish by default, so you can use the web app accelerator and increase the loading speed of any website that you host on our semi-dedicated servers. You will get 64 MB of system memory particularly for Varnish at no extra charge and you will be able to add an instance with no more than a couple of clicks from the Hepsia hosting Control Panel, which is included with the semi-dedicated packages. In case you want 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 immediately. You can also order more instances as an upgrade, so you can decide whether plenty of data will be cached for one site or whether the memory will be utilized by different Internet sites. The Hepsia Control Panel will allow you to restart or to remove any instance, to view the system log for it or to clear the cached files using 1-click buttons. To get the most out of the Varnish accelerator, you can allocate a dedicated IP to the Internet sites that will employ it.

Varnish in VPS Servers

Varnish is included by default with each of the VPS servers offered by us on the condition that the machine is ordered with the Hepsia Control Panel, so you can boost the work of your websites with only a few mouse clicks. The more powerful the plan, the more system memory will be available to Varnish, but even with a less powerful plan, the platform will be able to utilize several hundred MB, so even if you have several different websites, you’ll notice a serious decrease in the server load and a much better web page loading speed. The Varnish caching platform will have to work for a little while as the visitors browse the website and once the content has been cached, you will perceive the effect. One of the pluses of employing Varnish is that a less powerful and less expensive plan will accomplish the same job as a more costly one without the platform, so not only will your sites perform substantially better, but you will also spare some money.

Varnish in Dedicated Servers

You can employ Varnish in order to optimize the loading speed of any site that is hosted on a dedicated server with our company when the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the data caching platform ready to be used at no additional cost, but you will also exert total control over it via Hepsia’s user-friendly GUI. It will take only one mouse click to start or delete an instance or to clear the cached files associated with any website that’s using the Varnish platform and in case you are more trained, you can also check the platform’s system logs. Varnish comes with no less than 3 GB of virtual memory for website content caching purposes, so even if you run a lot of sites on your dedicated server and they all use the caching platform, the difference in their performance will be observable. You will simply need to wait for a little while until Varnish caches whatever pages the visitors access on their end. The Varnish platform performs best if the websites use a dedicated IP address, but due to the fact that our dedicated servers come with three free IP addresses, you’ll have all that you need.
