Varnish is a web application accelerator platform, which caches information for the sake of quicker response times. It’s occasionally called an HTTP reverse proxy as well and it works between a web server and a browser. When a website visitor loads a given page, its content is requested by the Internet browser, and then the web server processes this browser request and delivers the requested info. If Varnish is activated for a site, it will cache its pages at the first request and if the user opens a cached page once more, the data will be delivered by the accelerator platform and not by the server. The increased loading speed is a result of the considerably faster response speed that Varnish offers as compared with any server software. Of course, this doesn’t mean that the users will keep seeing the exact same content over and over again, because any update on any of the pages is reflected in the content that Varnish saves in its system memory.
Varnish in Cloud Hosting
You can take advantage of Varnish’s potential and optimize the load speed of your sites irrespective of the cloud hosting
plan that you’ve picked and you can activate and configure the data caching platform with a couple of mouse clicks from the intuitive graphical interface offered by our next-gen Hepsia Control Panel. During the procedure, you will be able to select two different things – how many sites will use the Varnish caching platform, i.e. the number of instances, and how much content will be cached, in other words – the amount of memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can use more instances and less memory and the other way around. If you’ve got plenty of content on a specific Internet site and you win plenty of visitors, more system memory will give you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish caching platform. Hepsia will provide you with easy 1-click controls for discontinuing or rebooting any instance, for clearing the cache associated with any Internet site and for checking detailed logs.
