Varnish is a web application accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the loading speed of any site, at times even by 100%, 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 server and to boost the browsing speed for the website visitors. Anytime a visitor opens a page on a given Internet site, the web browser request is taken care of by the web server and the requested information is sent as a reply. If Varnish is enabled, it caches the web pages that the website visitor browses and if any of them is loaded once more, it is served by Varnish and not by the web server directly. The performance increase is due to the fact that the accelerator handles the web requests significantly faster than any web server, which results in much faster browsing speeds for the users. If any content is updated meanwhile, the cached webpages will also be updated the next time somebody accesses them.

Varnish in Shared Web Hosting

If you host your Internet sites under a shared web hosting account with us, you’ll be able to activate Varnish with a few mouse clicks from your Control Panel. The content caching platform is available as an upgrade with all our hosting plans and you can select the number of the sites that will use it and the total storage space that will be used for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they’re not directly linked to each other, so you can decide whether you want a lot of memory for one single large-size site or less memory for several smaller ones. You can unlock the full potential of the Varnish caching platform in case the sites use a dedicated IP address. With the Control Panel, you can easily start/restart/discontinue an instance, clear the cached content independently for each site which uses the Varnish platform or view an elaborate log.

Varnish in Semi-dedicated Servers

The semi-dedicated servers that we offer will allow you to employ Varnish once your brand new semi-dedicated account is active, since the caching platform is available by default. 64 MB of system memory will be assigned to Varnish the second your account is activated, so you can use this workload balancing software as soon as your site has been published on the Internet. If you need more system memory, you can order 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated server momentarily. You can also increase the number of the websites that employ Varnish, or the so-called ‘instances’, which are not directly tied to the amount of memory that you use, which suggests that you will have more versatility. The Varnish platform will noticeably decrease the load on the semi-dedicated machine that your websites produce, so your site visitors can enjoy fast-loading web pages. You will be able to manage the Varnish caching platform without effort via the Control Panel using fast-access controls. You’ll be able to start/discontinue any of the instances that you have, to delete the cached data associated with any of your Internet sites or to see system logs.

Varnish in Dedicated Servers

All dedicated servers that are ordered with the in-house built Hepsia web hosting Control Panel include Varnish, which is one of the pre-installed software platforms that you’ll get with the server. The Varnish platform can be activated and managed with no effort via Hepsia’s easy-to-use GUI and, with no more than one single click of the mouse, you can view an elaborate system log, create or reboot an instance, delete the cached content for any Internet site and much, much more. Shortly after you activate Varnish for a certain domain or subdomain, it will begin caching the web pages accessed by the site visitors and once it has cached enough content, you’ll perceive a significantly faster site performance in addition to a decreased load on the server. With Varnish-dedicated virtual memory starting at 3 GB, you will be able to use the platform for workload distribution purposes even if you run plenty of websites on your machine.
