Varnish is a web accelerator, which has been gaining a lot in popularity in recent years, as it can increase the loading speed of any Internet site, at times even by 100%, based on the content itself. This tool is sometimes referred to as an HTTP reverse proxy as well and is used to lower the overall server load and to improve the access speed for the site visitors. Each time a visitor loads a page on a specific website, the browser request is processed by the web server and the requested info is sent as a response. If the Varnish accelerator is enabled, it caches the web pages that the website visitor opens and in case any of them is opened once again, it’s fetched by Varnish and not by the web server directly. The improvement in the performance is due to the fact that the accelerator processes the web requests significantly quicker than any web server, which results in much faster browsing speeds for the site visitors. In case any content is updated in the meantime, the cached webpages will also be updated the next time someone attempts to access them.

Varnish in Hosting

In case you host your websites in a hosting account with us, you will be able to activate Varnish with a few clicks of the mouse through your hosting Control Panel. The caching platform comes as an optional upgrade with all our packages and you can select how many sites will use it and the total amount of system memory that will be used for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they aren’t linked directly to each other, so you can choose if you want lots of memory for one large-sized site or less memory for several smaller ones. You can use the full potential of the Varnish caching platform in case the sites use a dedicated IP address. Using the Control Panel, you can easily start/reboot/discontinue an instance, delete the cached files independently for each website that uses the Varnish platform or check a detailed system log.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain the Varnish platform at no additional charge and you’ll exert full control over it via an extremely easy-to-navigate GUI – you will be able to start, to discontinue or to restart an instance, to view a comprehensive log, to clear the cache associated with any website and much, much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you’ve got high-demand sites with numerous visitors, you’ll notice the much faster website loading times and the lowered server load. This will happen shortly after you begin using Varnish, since it will need some time to cache the website content that visitors browse. You can get the most out of the platform’s potential if the sites that are using it use also a dedicated IP, but considering the fact that your dedicated server includes a few IP addresses by default, you will not need to pay anything on top of the monthly charge for the server itself.
