Varnish is a web accelerator tool, which has been gaining a lot of popularity lately, because it can increase the load speed of any website, sometimes even by 100%, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to accelerate the access speed for the website visitors. Whenever a visitor opens a page on a certain site, the browser request is taken care of by the web server and the requested info is served as a response. If the Varnish accelerator is activated, it caches the pages that the visitor opens and if any of them is accessed once again, it is fetched by Varnish and not by the web server directly. The boost in the overall performance is due to the fact that the accelerator handles the web requests substantially faster than any web server, which leads to much faster browsing speeds for the users. In case any data is changed in the meantime, the cached pages will also be updated the next time someone accesses them.

Varnish in Shared Website Hosting

Varnish is available as an optional upgrade with each and every Linux shared website hosting and if you’d like to use it, you can add it to your hosting account through the Upgrades menu in your Hepsia Control Panel. There are two separate things that can be upgraded – the instances and the system memory. The first one refers to the number of the websites that you wish to use Varnish for, whereas the second, which is offered in increments of 32 MB, pertains to the maximum amount of content that the content caching platform can cache at any particular time. Hepsia’s easy-to-use GUI will allow you to shut down or to reboot any instance, to see comprehensive logs or to get rid of the platform’s cache with just click of the mouse. For optimum results, you can employ a dedicated IP for the sites that will use the platform. With Varnish, your website will load substantially faster, which means more satisfied website visitors and potential customers.

Varnish in Semi-dedicated Servers

All our Linux semi-dedicated hosting plans include Varnish by default, so you can make full use of the web app accelerator tool and improve the load speed of any site that you host on our semi-dedicated servers. You will get 64 MB of memory exclusively for the Varnish accelerator at no extra charge and you’ll be able to add an instance with no more than a few mouse clicks through the Hepsia hosting Control Panel, which is included with the semi-dedicated packages. If you need more memory, the latter is available in increments of 32 megabytes through the Upgrades section of the Control Panel and it will be available to you instantaneously. You can also add more instances as an upgrade, so you can choose whether plenty of content will be cached for one site or whether the available memory will be used by several sites. The Hepsia Control Panel will allow you to restart or to delete any instance, to check the system log file associated with it or to delete the cached files using single-click buttons. To get the most out of the Varnish accelerator, you can get a dedicated IP address for the websites that will employ it.

Varnish in VPS Servers

The Varnish data caching platform comes by default with all VPS servers offered by our company given that the VPS is ordered with the Hepsia Control Panel, so you can enhance the performance of your websites with only a few clicks. The more powerful the plan, the more memory will be available to Varnish, but even with a lower-end plan, the platform will be able to utilize several hundred MB, so even if you run several different sites, you will notice a significant reduction in the server load and a considerably better website loading speed. The Varnish platform will have to work for a little while while the users navigate the website and as soon as the website content has been cached, you’ll see the effects. One of the pluses of using Varnish is that a lower-end and less costly VPS package will accomplish the exact same job as a more pricey one without the platform, so not only will your Internet sites work substantially better, but you’ll also save some money.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish data caching platform at no extra cost and you’ll have complete control over it through a very simple-to-navigate GUI – you will be able to start, to terminate or to reboot an instance, to see a detailed system log, to delete the cache associated with any Internet site and much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you run heavy Internet sites with lots of visitors, you’ll notice the tremendously better website load times and the lowered load on the dedicated server. This will happen shortly after you start using Varnish, as it will need some time to cache the pages that visitors request. You can make the most of the platform’s capacity if the Internet sites that are using it also use a dedicated IP address, but due to the fact that your dedicated server comes with a couple of IPs by default, you won’t have to pay anything on top of your monthly fee for the machine itself.
