Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, because it can increase the load speed of any Internet site, sometimes even by one hundred percent, based on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to lower the overall load on the server and to enhance the browsing speed for the site visitors. Whenever a visitor opens a page on a certain site, the browser request is handled by the web server and the requested info is sent as a reply. If the Varnish accelerator is enabled, it caches the web pages that the website visitor browses and if any of them is loaded for a second time, it’s served by Varnish and not by the web server directly. The improvement in the performance comes from the fact that the accelerator processes the web requests tremendously faster than any web server, which results in much faster browsing speeds for the users. If any data is modified meanwhile, the cached webpages will also be updated the next time somebody attempts to open them.
Varnish in Cloud Hosting
Varnish comes as an optional upgrade with each Linux cloud hosting and if you want to use it, you can add it to your website hosting account via the Upgrades menu in your Hepsia Control Panel. There’re two different features that can be upgraded – the instances and the system memory. The first one depends on the number of the sites that you’d like to use Varnish for, whereas the second, which is available in increments of 32 megabytes, pertains to the total amount of data that the platform can cache at any particular time. The Hepsia Control Panel’s time and effort saving graphical interface will permit you to cancel or to reboot any instance, to check exhaustive logs or to get rid of the platform’s cache with just one click. For maximum results, you can use a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your site will load tremendously faster, meaning more happy site users and prospective customers.
