Varnish is a web app accelerator, which has been gaining a lot of popularity lately, as it can increase the loading speed of any site, sometimes even by one hundred percent, depending on the content. This tool is sometimes called an HTTP reverse proxy as well and is used to reduce the overall load on the physical server and to boost the access speed for the site visitors. Every time a visitor opens a page on a given website, the browser request is taken care of by the web server and the requested information is delivered as a reply. If the Varnish accelerator is enabled, it caches the pages that the site visitor opens and if any of them is opened again, it’s served by Varnish and not by the web server directly. The boost in the performance comes from the fact that the accelerator processes the web requests considerably faster than any web server, which results in much faster browsing speeds for the users. If any content is updated in the meantime, the cached webpages will also be ‘refreshed’ the next time someone tries to access them.

Varnish in Website Hosting

You can unleash Varnish’s full potential and accelerate the loading speed of your websites irrespective of the website hosting plan that you have chosen and you can add and configure the platform with a couple of mouse clicks from the easy-to-use interface offered by our next-generation Hepsia hosting Control Panel. In the meantime, you’ll be able to select two separate things – how many websites will use the Varnish caching platform, in other words – the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not linked to the number of instances, so you can add more instances and less memory and the other way around. If you’ve got lots of content on a particular website and you win a lot of site visitors, more system memory will give you better results. You may also consider employing a dedicated IP for the Internet sites that will use the Varnish caching platform. The Hepsia Control Panel will offer you simple 1-click buttons for terminating or restarting any instance, for erasing the cache for each Internet site and for checking detailed logs.

Varnish in Semi-dedicated Servers

The semi-dedicated servers that we’re offering will permit you to use Varnish once your brand new semi-dedicated server account has been opened, since the data caching platform is available by default. 64 MB of system memory will be allocated to Varnish the moment your account is activated, so you can take advantage of this workload distribution software as soon as you launch your site. In case you need more system memory, you can add 32 megabytes at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be allocated to your semi-dedicated server immediately. You can also increase the number of the websites that employ Varnish, or the so-called ‘instances’, which are not directly linked to the amount of memory that you use, which means that you’ll enjoy more versatility. The caching platform will noticeably lower the load on the machine caused by your websites, so your site visitors can enjoy fast-loading pages. You’ll be able to manage Varnish effortlessly via your Hepsia Control Panel using quick-access buttons. You’ll be able to start/disable any of the instances that you’ve got, to delete the cache for any of your sites or to check system logs.
