Varnish is a website accelerator, which has been gaining a lot of popularity lately, as it can increase the load speed of any site, sometimes even by one hundred percent, based on the content itself. This tool is sometimes called a caching HTTP reverse proxy too and is used to lower the overall load on the server and to boost the browsing speed for the website visitors. Whenever a visitor loads a page on a specific website, the web browser request is taken care of by the web server and the requested content is returned as a reply. If Varnish is enabled, it caches the web pages that the website visitor opens and if any of them is loaded once again, it’s fetched by Varnish and not by the web server directly. The improvement in the performance comes from the fact that the accelerator handles the web requests significantly quicker than any web server, which leads to much faster browsing speeds for the website visitors. If any content is edited meanwhile, the cached webpages will also be updated the next time somebody attempts to open them.

Varnish in Web Hosting

In case you host your sites in a web hosting account with our company, you’ll be able to activate Varnish with a few mouse clicks from your Control Panel. The data caching platform is available as an upgrade with all our hosting packages and you can choose the number of the sites that will use it and the maximum storage space that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they are not linked directly to each other, so you can decide if you need lots of memory for one large-scale website or less memory for multiple smaller ones. You can unleash the full potential of the Varnish caching platform in case the sites use a dedicated IP. With the Control Panel, you can easily start/restart/shut down an instance, delete the cached content independently for each website that uses Varnish or see an elaborate system log file.

Varnish in Semi-dedicated Servers

The Varnish caching platform is part of the default set of services that you will get in case you decide to host your Internet sites in a semi-dedicated server account. You can set it up for any of your sites through our advanced Hepsia Control Panel. The default amount of system memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this caching platform simultaneously. Since these two features are not bound to each other, you can use a couple of instances with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for one single website. The Varnish platform performs best if you set a dedicated IP for the websites that utilize its power. The Hepsia Control Panel will offer you a simple means of rebooting any instance. In addition, you will be able to delete the cached contents with just one single click.

Varnish in VPS Servers

You can use the load balancing potential of Varnish with each of our Linux VPS plans when you choose Hepsia as your hosting Control Panel. The Varnish caching platform comes by default and the amount of system memory that it’ll be able to use to cache the content of your sites is dependent on the given plan that you have picked, but even with the lower-end plans, you will have at least several hundred MB of system memory at your disposal solely for content caching purposes. This amount is sufficient enough to optimize the work of numerous Internet sites. It will take a little time for you to distinguish the results, since Varnish caches the content that website visitors access, but soon thereafter you will notice the considerably decreased load on the server and the improved website loading speed. The Varnish caching platform will allow you to make use of a lower-end Virtual Private Server plan for Internet sites which would usually require a more costly hosting solution.

Varnish in Dedicated Servers

All dedicated web hosting plans that are ordered with the tailor-made Hepsia web hosting Control Panel include Varnish, which is one of the pre-installed platforms that you’ll get with the dedicated machine. The Varnish caching platform can be set up and administered with no effort from Hepsia’s simple-to-work-with interface and, with no more than one single mouse click, you can see an exhaustive system log, create or reboot an instance, delete the cached data associated with any site and much, much more. Shortly after you set up Varnish for a specific domain or subdomain, it will start caching the pages accessed by your site visitors and once it has cached enough web content, you’ll witness a substantially better website performance in addition to a decreased load on your dedicated machine. With Varnish-dedicated system memory starting at 3 GB, you will be able to use the software platform for workload balancing purposes even if you host plenty of Internet sites on your dedicated machine.
