Varnish is a data caching platform, which is occasionally referred to as a caching HTTP reverse proxy. It’s a web application accelerator that can improve the load speed of a website by up to 1000%, based on the content itself. Anytime a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor accesses it again. In this way, the web browser request from the visitor is not processed by the web server and the page will load considerably faster, as the Varnish caching platform can deliver content many times faster than any web server software. The result is a substantially faster loading website, which means a greatly improved website browsing experience. When any of the cached pages is updated on the actual site, the information that Varnish stores in its system memory is updated as well, so the site visitors won’t end up seeing outdated content.
Varnish in Shared Web Hosting
You can take advantage of Varnish’s full potential and boost the load speed of your websites irrespective of the shared web hosting plan that you have chosen and you can activate and configure the content caching platform with a few mouse clicks through the easy-to-work-with interface offered by our next-gen Hepsia hosting Control Panel. In the meantime, you’ll be able to select two different things – how many Internet sites will employ the Varnish platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of system memory. The latter is available in increments of 32 MB and is not bound to the number of instances, so you can use more instances and less memory and vice versa. In case you’ve got a lot of content on a given website and you draw plenty of site visitors, more memory will guarantee you better results. You may also consider using a dedicated IP for the Internet sites that will use the Varnish platform. Hepsia will provide you with simple one-click controls for deleting or rebooting any instance, for erasing the cache for any website and for viewing exhaustive logs.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish platform at no additional charge and you will exert complete control over it through an amazingly user-friendly GUI – you’ll be able to start, to stop or to restart an instance, to see an in-depth system log, to delete the cached files associated with any site and much more. The Varnish platform will have several gigabytes of system memory at its disposal, so even if you’ve got large-sized sites with lots of visitors, you will notice the substantially faster site loading speeds and the less load on the dedicated server. This will become a fact soon after you start using Varnish, as it will need some time to cache the pages that visitors access. You can take full advantage of the platform’s capacity if the sites that are using it use also a dedicated IP, but considering the fact that your dedicated server comes with several IP addresses by default, you will not need to pay anything on top of the monthly charge for the server itself.
