Varnish is a data caching platform, which is sometimes referred to as a caching HTTP reverse proxy. It’s a web accelerator that can increase the loading speed of a website by up to 1000 percent, based on its content. Each time a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor opens it again. Thus, the web browser request from the visitor is not handled by the web server and the page will open significantly faster, as the Varnish platform can serve content many times faster than any web server software. The result will be a much faster loading site, which means an enormously improved visitor experience. In case any of the cached web pages is updated on the live website, the data that Varnish saves in its system memory is updated as well, so the site visitors won’t end up seeing out-of-date info.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with each of our Linux cloud hosting. You can add it to your web hosting account from the Hepsia Control Panel, which is available with all shared web hosting packages and you will get an amazingly intuitive GUI, which will grant you full control over the caching system. Using one-click quick-access controls, you can reboot or deactivate any of the instances, in other words – Varnish will no longer work for a specific website. You can also see an exhaustive log or erase the cache associated with any of the sites. When you add Varnish to your shared web hosting plan, you’ll be able to choose the total amount of system memory that will be available to you for caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 MB and, for optimum performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will permit you to take full advantage of your websites and to have a lot of satisfied website users.
