Varnish is a website accelerator, which has been gaining a lot in popularity in recent years, because it can increase the speed of any Internet site, sometimes even by 100 percent, based on the content itself. This tool is occasionally called a caching HTTP reverse proxy too and is used to decrease the overall server load and to increase the access speed for the site visitors. Every time a visitor accesses a page on a given site, the browser request is processed by the web server and the requested content is delivered as a reply. If the Varnish accelerator is activated, it caches the web pages that the site visitor browses and if any of them is accessed for a second time, it is fetched by Varnish and not by the server directly. The improvement in the performance comes from the fact that the accelerator handles the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is modified in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody opens them.
Varnish in Shared Hosting
Varnish comes as an optional upgrade with each of our shared hosting. You can add it to your web hosting account via the Hepsia Control Panel, which is available with all shared web hosting packages and you’ll get a pretty simple-to-use GUI, which will give you full control over the data caching system. Using one-click quick-access controls, you can reboot or stop any of the instances, in other words – Varnish will no longer be enabled for a given site. You can also view an in-depth log file or delete the cache for any of the Internet sites. When you add Varnish to your web hosting plan, you will be able to choose the maximum amount of memory that will be available to you for content caching purposes and how many websites will use Varnish. You can always add more memory in increments of 32 megabytes and, for top performance, you can assign a dedicated IP address to the websites that will use Varnish. This will permit you to take full advantage of your sites and to have numerous satisfied website users.
Varnish in VPS Servers
You can take advantage of Varnish with all our VPS server plans at no extra cost, since the data caching platform is pre-installed and is included by default. The one and only precondition is that the virtual machine must be ordered with the Hepsia hosting Control Panel, through which you’ll be able to activate Varnish for any of your Internet sites with just a few clicks of the mouse. Each VPS package features a different amount of memory for data caching purposes, but you’ll get at least several hundred megabytes, which is quite sufficient even for several large-sized websites. Soon after you enable the Varnish platform, it will start caching the content that your website visitors browse, so you will notice the tremendously better Internet site load speeds and the lowered load on the Virtual Private Server very soon. The platform will permit you to use a less high-priced server, as you won’t require that many resources to ensure the correct operation of your Internet sites even if you manage high-demand Internet sites with a lot of visitors. Best results are achieved if the sites which use Varnish use also a dedicated IP.
