Varnish is a web accelerator tool, which has been gaining a lot in popularity lately, because it can increase the speed of any website, sometimes even by one hundred percent, based on the content. This tool is sometimes called a caching HTTP reverse proxy too and is used to reduce the overall server load and to accelerate the browsing speed for the site visitors. Each time a visitor accesses a page on a certain site, the web browser request is processed by the web server and the requested info is served as a response. If the Varnish accelerator is enabled, it caches the pages that the website visitor opens and if any of them is accessed 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 processes the browser requests tremendously faster than any web server, which results in much faster browsing speeds for the users. If any data is edited meanwhile, the cached pages will also be updated the next time someone opens them.
Varnish in Hosting
You can take advantage of Varnish’s potential and optimize the speed of your sites regardless of the hosting package that you’ve chosen and you can add and set up the data caching platform with a couple of mouse clicks using the simple-to-work-with interface offered by our next-gen Hepsia Control Panel. During the process, you will be able to choose two different things – how many websites will employ the Varnish platform, in other words – the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 megabytes and is not tied to the number of instances, so you can use more instances with less memory and vice versa. If you’ve got lots of content on a specific site and you win numerous visitors, more system memory will give you a better result. You may also consider using a dedicated IP for the Internet sites that will use Varnish. Hepsia will offer you easy 1-click controls for discontinuing or restarting any instance, for deleting the cache associated with each site and for viewing detailed logs.
Varnish in Dedicated Servers Hosting
All Linux dedicated servers hosting which are ordered with the custom-developed Hepsia website hosting Control Panel include Varnish, which is one of the pre-installed platforms that you will get with the dedicated machine. The Varnish content caching platform can be enabled and administered without effort via the Hepsia Control Panel’s easy-to-use interface and, with no more than one click of the mouse, you can see an elaborate system log, create or reboot an instance, clear the cached data for any Internet site and much more. Soon after you enable Varnish for a certain domain or subdomain, it will begin caching the web pages accessed by your visitors and as soon as it has cached enough content, you’ll perceive a significantly better website performance in addition to a lowered load on the dedicated server. With Varnish-dedicated system memory starting at 3 GB, you’ll be able to use the platform for workload distribution purposes even if you host multiple Internet sites on your server.
