Varnish is a website accelerator tool, which has been gaining a lot of popularity lately, as it can increase the loading speed of any website, sometimes even by 100%, depending on the content. This tool is sometimes called a caching HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to increase the browsing speed for the site visitors. Every time a visitor opens a page on a given website, the browser request is processed by the web server and the requested information is returned as a response. If the Varnish accelerator is activated, it caches the web pages that the website visitor browses and if any of them is accessed for a second time, it’s fetched by Varnish and not by the server directly. The increase in the overall performance comes from the fact that the accelerator handles the browser requests substantially quicker than any web server, which results in much faster browsing speeds for the users. In case any data is modified in the meantime, the cached pages will also be ‘refreshed’ the next time somebody tries to open them.
Varnish in Cloud Website Hosting
You can unleash Varnish’s full potential and accelerate your websites’ speed regardless of the cloud website hosting plan that you’ve chosen and you can add and set up the content caching platform with a couple of mouse clicks through the user-friendly interface offered by our cutting-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, in other words – the number of instances, and how much information will be cached, in other words – the amount of memory. The latter comes in increments of 32 MB and is not tied to the number of instances, so you can add more instances with less memory and vice versa. In case you have a lot of content on a certain site and you get plenty of visitors, more system memory will guarantee you a better result. You may also consider employing a dedicated IP address for the websites that will use the Varnish platform. Hepsia will provide you with simple 1-click buttons for disabling or rebooting any instance, for erasing the cache for any Internet site and for seeing elaborate system logs.
