Varnish is a data caching platform, which is sometimes referred to as an HTTP reverse proxy. It is a website accelerator tool that can improve the load speed of a website by up to 1000 percent, depending on the content itself. Anytime a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor opens it again. In this way, the browser request from the visitor is not processed by the web server and the page will load considerably faster, since Varnish can serve data many times faster than any server software. The end result is a significantly faster loading site, which means a much-improved visitor experience. If any of the cached pages is updated on the actual site, the data that Varnish saves in its memory is updated as well, so the visitors will never see old data.
Varnish in Cloud Hosting
You can use Varnish’s full potential and boost the speed of your sites irrespective of the cloud hosting plan that you’ve chosen and you can enable and configure the data caching platform with a couple of clicks of the mouse via the simple-to-work-with GUI offered by our leading-edge Hepsia hosting Control Panel. During the process, you will be able to select two different things – how many websites will employ the Varnish platform, i.e. the number of instances, and how much content will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 megabytes and is not linked to the number of instances, so you can use more instances and less memory and vice versa. If you have lots of content on a certain site and you win lots of visitors, more memory will guarantee you better results. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish caching platform. Hepsia will offer you easy 1-click controls for cancelling or restarting any instance, for erasing the cache associated with each site and for checking detailed logs.
