Varnish is a web app accelerator, which has been gaining a lot in popularity in recent years, because it can increase the load speed of any Internet site, at times even by one hundred percent, depending on the content. This tool is occasionally called a caching HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to accelerate the browsing speed for the site visitors. Whenever a visitor opens a page on a particular site, the browser request is taken care of by the web server and the requested info is sent as a reply. If the Varnish accelerator is activated, it caches the web pages that the website visitor browses and in case any of them is opened once again, it’s fetched by Varnish and not by the server directly. The boost in the overall performance comes from the fact that the accelerator handles the browser requests significantly faster than any web server, which results in much faster browsing speeds for the site visitors. If any content is edited meanwhile, the cached pages will also be ‘refreshed’ the next time someone accesses them.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is part of the standard set of services that you will receive when you decide to host your sites in a semi-dedicated server account. You can activate it for any of your sites through our cutting-edge Hepsia Control Panel. The default amount of system memory that the Varnish caching platform can use to cache content is 64 megabytes, but in case you decide that you want more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this caching platform simultaneously. Since these two features aren’t tied to each other, you can use several sites with the default memory or you can get more memory in increments of 32 MB and use all of it for a single Internet site. The Varnish caching platform performs best if you allocate a dedicated IP to the Internet sites that utilize its power. Hepsia will offer you an easy means of rebooting any instance. What’s more, you will be able to clear the cached data with only a click.

Varnish in Dedicated Servers Hosting

All Linux dedicated servers hosting that are ordered with the custom-developed Hepsia web hosting Control Panel include Varnish, which is among the pre-installed software platforms that you’ll get with the machine. The Varnish caching platform can be set up and managed without efforts through Hepsia’s easy-to-work-with GUI and, with no more than one click, you can see an elaborate system log, add or reboot an instance, delete the cached files associated with any Internet site and much, much more. Shortly after you enable the Varnish platform for a certain domain or subdomain, it will begin caching the pages opened by the site visitors and once it has cached enough content, you’ll observe a significantly better website performance in addition to a lowered load on your dedicated server. With Varnish-dedicated system memory starting at 3 GB, you will be able to use the software platform for workload distribution purposes even if you run an enormous number of sites on the dedicated server.
