Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, as it can increase the load speed of any site, sometimes even by one hundred percent, based on the content itself. This tool is sometimes referred to as an HTTP reverse proxy too and is used to reduce the overall load on the physical server and to increase the browsing speed for the site visitors. Every time a visitor accesses a page on a given website, the web browser request is handled by the web server and the requested information is returned as a reply. If Varnish is enabled, it caches the web pages that the visitor opens and if any of them is accessed again, it’s fetched by Varnish and not by the web server directly. The improvement in the performance comes from the fact that the accelerator handles the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the users. If any data is changed meanwhile, the cached pages will also be updated the next time somebody accesses them.

Varnish in Cloud Hosting

In case you host your websites in a cloud hosting account with us, you’ll be able to add Varnish with several mouse clicks through your Control Panel. The data caching platform is offered as an optional upgrade with all our shared web hosting plans and you can choose the number of the websites that will use it and the total storage space that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they’re not directly tied to each other, so you can choose if you want a lot of memory for a single large website or less memory for multiple smaller ones. You can unleash the full potential of Varnish in case the websites use a dedicated IP address. With the Control Panel, you can effortlessly start/reboot/discontinue an instance, delete the cached files individually for each website which employs Varnish or see an in-depth log.

Varnish in Semi-dedicated Servers

Varnish is part of the basic set of services that you’ll receive if you decide to host your Internet sites in a semi-dedicated server account. You can enable it for any of your Internet sites via our avant-garde Hepsia Control Panel. The default amount of memory that Varnish can use to cache content is 64 MB, but if you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this platform simultaneously. As these two features aren’t tied to each other, you can use a few Internet sites with the default memory or you can add more memory in increments of 32 megabytes and use all of it for one single site. Varnish works best if you allocate a dedicated IP address to the websites that utilize its power. Hepsia will give you an easy means of rebooting any instance. In addition, you will be able to delete the cached contents with only one click of the mouse.

Varnish in Dedicated Servers

You can employ Varnish in order to enhance the speed of any site that is hosted on a dedicated server with us when the Hepsia hosting Control Panel is installed on it. Not only will you get the content caching platform ready to be used at no additional fee, but you’ll also exert total control over it via Hepsia’s simple-to-work-with graphical interface. It’ll take only one mouse click to start or cancel an instance or to clear the cached content for any site that’s using the Varnish platform and if you’re more practiced, you can also check the platform’s system logs. Varnish comes with no less than 3 gigabytes of memory for caching purposes, so even in case you host a lot of Internet sites on your machine and they all use the platform, the difference in their overall performance will be visible. You’ll just have to wait for a little while till Varnish caches whatever pages the site visitors open on their end. The Varnish platform works best when the sites use a dedicated IP, but due to the fact that our dedicated servers include 3 free IPs, you’ll have all that you need.
