Varnish is a web application accelerator, which has been gaining a lot in popularity in recent years, as it can increase the loading speed of any website, at times even by 100 percent, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy too and is used to decrease the overall load on the physical server and to improve the access speed for the site visitors. Whenever a visitor opens a page on a certain Internet site, the web browser request is taken care of by the web server and the requested content is delivered as a response. If Varnish is activated, it caches the pages that the visitor opens and if any of them is opened for a second time, it is served by Varnish and not by the server directly. The performance boost comes from the fact that the accelerator processes the browser requests tremendously faster than any web server, which results in much faster browsing speeds for the site visitors. In case any data is changed in the meantime, the cached webpages will also be updated the next time somebody tries to access them.
Varnish in Cloud Hosting
You can unlock Varnish’s potential and accelerate your websites’ load speed regardless of the cloud hosting
package that you’ve picked and you can add and set up the platform with a few clicks through the easy-to-work-with graphical interface offered by our advanced Hepsia hosting Control Panel. During the process, you’ll be able to choose two separate things – how many Internet sites will employ Varnish, i.e. the number of instances, and how much data will be cached, in other words – the amount of 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. In case you’ve got lots of content on a certain Internet site and you win plenty of website visitors, more system memory will give you better results. You may also consider employing a dedicated IP for the websites that will use the Varnish caching platform. Hepsia will provide you with easy 1-click controls for shutting down or rebooting any instance, for deleting the cache associated with any website and for checking exhaustive logs.
