Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, as it can increase the load speed of any site, sometimes even by 100 percent, depending on the content. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to reduce the overall load on the physical server and to accelerate the access speed for the website visitors. Every time a visitor accesses a page on a given website, the web browser request is handled by the web server and the requested data is returned as a reply. If Varnish is enabled, it caches the pages that the site visitor browses and if any of them is opened once more, it is delivered by Varnish and not by the web server directly. The boost in the overall performance is due to the fact that the accelerator processes the web requests considerably quicker than any web server, which leads to much faster browsing speeds for the users. If any data is modified in the meantime, the cached webpages will also be updated the next time somebody attempts to open them.

Varnish in Cloud Hosting

If you host your sites in a cloud hosting account with us, you will be able to activate Varnish with several mouse clicks through your Control Panel. The caching platform comes as an upgrade with all our hosting plans and you can select the number of the websites that will use it and the total amount of system memory that will be available for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they are not tied directly to each other, so you can decide whether you want a lot of memory for a single large website or less memory for several smaller ones. You can take advantage of the full potential of Varnish if the websites use a dedicated IP. With the hosting Control Panel, you can swiftly start/reboot/discontinue an instance, delete the cached contents independently for each website that employs Varnish or check an elaborate log file.

Varnish in Semi-dedicated Servers

The Varnish caching platform is included in the basic service set that you’ll obtain when you decide to host your websites under a semi-dedicated server account. You can set it up for any of your sites through our cutting-edge Hepsia Control Panel. The default memory that Varnish can use to cache content is 64 megabytes, but if you decide that you want 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 platform simultaneously. As these two things are not bound to each other, you can use a few websites with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for a single website. Varnish performs best if you allocate a dedicated IP to the sites that utilize its power. Hepsia will give you an easy means of rebooting any instance. In addition, you’ll be able to clear the cached files with only one single mouse click.

Varnish in Dedicated Servers

All dedicated web hosting plans which are ordered with the custom Hepsia hosting Control Panel come with Varnish, which is one of the pre-installed software platforms that you’ll get with the server. The Varnish content caching platform can be configured and managed without effort from Hepsia’s easy-to-use interface and, with no more than a click, you can browse an exhaustive system log, create or restart an instance, clear the cached content associated with any site and much, much more. Shortly after you enable the Varnish platform for a certain domain or subdomain, it will begin caching the web pages loaded by your visitors and once it has cached enough content, you will observe a considerably 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 software platform for workload distribution purposes even if you run a lot of Internet sites on the server.
