Varnish is a web app accelerator platform, which caches information for quicker access. It is sometimes referred to as a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a site visitor loads a particular page, its content is requested by the Internet browser, and then the web server handles this request and returns the necessary content. If Varnish is activated for a certain website, it will cache its pages at the very first request and in case the visitor opens a cached page again, the data will be delivered by the caching platform and not by the web server. The boosted loading speed is a result of the significantly faster response time that the Varnish platform offers as compared to any web server software. At the same time, this does not mean that the site visitors will continue seeing the same content again and again, because any modification on any of the pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Shared Website Hosting

You can unlock Varnish’s full potential and increase the loading speed of your sites regardless of the shared website hosting plan that you have selected and you can activate and configure the platform with a couple of clicks of the mouse using the intuitive interface offered by our next-generation Hepsia hosting Control Panel. In the meantime, you’ll be able to choose two separate things – how many sites will employ Varnish, i.e. the number of instances, and how much information will be cached, i.e. 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 use more instances with less memory and the other way around. If you’ve got plenty of content on a certain site and you gain a lot of site visitors, more memory will guarantee you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish platform. Hepsia will provide you with simple one-click buttons for disabling or restarting any instance, for clearing the cache associated with each Internet site and for seeing exhaustive logs.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is included in the standard set of services that you will obtain when you choose to host your websites under a semi-dedicated server account. You can activate it for any of your sites through our leading-edge Hepsia Control Panel. The default amount of memory that Varnish can use to cache data is 64 MB, but if 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, in other words – the number of the sites that can use this caching platform at the same time. Since these two things aren’t linked to each other, you can use a couple of Internet sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for one single web site. The Varnish platform performs best if you assign a dedicated IP address to the websites that utilize its power. Hepsia will give you a simple means of restarting any instance. Furthermore, you will be able to delete the cached content with only one single mouse click.

Varnish in Dedicated Servers

All dedicated servers which are ordered with the custom-built Hepsia hosting Control Panel include Varnish, which is among the pre-installed software platforms that you will get with the server. The Varnish data caching platform can be set up and managed without effort through Hepsia’s simple-to-navigate GUI and, with no more than one mouse click, you can see a detailed system log, create or restart an instance, delete the cached files associated with any website and much, much more. Shortly after you configure the Varnish platform for a certain domain or subdomain, it will start caching the webpages opened by the website visitors and as soon as it has cached enough content, you will perceive a tremendously better website performance as well as a decreased load on the server. With Varnish-dedicated virtual memory starting at 3 GB, you will be able to use the software platform for workload balancing purposes even if you host a huge number of Internet sites on the dedicated server.
