Varnish is a content caching platform, which is occasionally referred to as a caching HTTP reverse proxy. It’s a website accelerator that can accelerate the loading speed of a website by up to one thousand percent, based on its content. Anytime a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor accesses it again. In this way, the browser request from the visitor is not handled by the web server and the page will open substantially faster, since Varnish can serve data many times faster than any server software. The end result is a much faster loading site, which means a much-improved browsing experience. If any of the cached webpages is updated on the live Internet site, the content that Varnish saves in its memory is ‘refreshed’ too, so the site visitors won’t end up seeing out-of-date data.
Varnish in Cloud Web Hosting
You can unlock Varnish’s full potential and optimize your websites’ speed irrespective of the cloud web hosting
plan that you have chosen and you can enable and configure the content caching platform with several clicks of the mouse via the easy-to-work-with graphical interface offered by our next-gen Hepsia hosting Control Panel. In the meantime, you will be able to select two separate things – how many websites will use the Varnish platform, i.e. the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can order more instances and less memory and the other way around. In case you’ve got plenty of content on a particular Internet site and you win plenty of website visitors, more memory will give you a better result. You may also consider using a dedicated IP address for the websites that will use Varnish. The Hepsia Control Panel will provide you with simple one-click buttons for discontinuing or rebooting any instance, for deleting the cache associated with each Internet site and for checking detailed logs.
