Varnish is a web application accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the speed of any site, at times even by 100 percent, based on the content itself. This tool is sometimes referred to as an HTTP reverse proxy as well and is used to decrease the overall load on the server and to boost the browsing speed for the site visitors. Whenever a visitor opens a page on a particular site, the web browser request is processed by the web server and the requested content is served as a reply. If Varnish is activated, it caches the pages that the website visitor browses and if any of them is opened once again, it is fetched by Varnish and not by the server directly. The performance boost is due to the fact that the accelerator processes the web requests considerably faster than any web server, which leads to much faster browsing speeds for the website visitors. In case any content is modified meanwhile, the cached pages will also be ‘refreshed’ the next time someone attempts to access them.
Varnish in Cloud Hosting
In case you host your websites in a cloud hosting account with our company, you will be able to activate Varnish with a couple of mouse clicks from your Control Panel. The data caching platform is available as an optional upgrade with all our web hosting plans and you can select how many websites will use it and the maximum amount of system memory that will be available for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they are not directly tied to each other, so you can choose whether you want a lot of memory for one large site or less memory for multiple smaller ones. You can use the full potential of the Varnish platform in case the websites use a dedicated IP address. With the Control Panel, you can easily start/reboot/terminate an instance, clear the cached contents independently for each site that employs Varnish or view an exhaustive log file.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated hosting packages include Varnish by default, so you can make full use of the web app accelerator and increase the speed of any website that you host on our platform. You will get 64 MB of memory exclusively for Varnish at no additional cost and you will be able to activate an instance with no more than a few mouse clicks from the Hepsia hosting Control Panel, which comes with the semi-dedicated server packages. In case you need more memory, the latter is available in increments of 32 MB through the Upgrades section of the Control Panel and it will be at your disposal instantaneously. You can also add more instances as an upgrade, so you can decide whether a lot of data will be cached for a single website or if the memory will be utilized by several Internet sites. The Hepsia Control Panel will permit you to restart or to disable any instance, to check the system log file for it or to clear the cached content using single-click buttons. To take full advantage of the Varnish accelerator, you can set a dedicated IP for the sites which will use it.
Varnish in Dedicated Hosting
In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish content caching platform at no extra cost and you will exert complete control over it through a truly easy-to-use GUI – you will be able to start, to terminate or to reboot an instance, to view an exhaustive log, to clear the cached data associated with any site and much, much more. Varnish will have several GB of system memory at its disposal, so even if you manage high-demand Internet sites with numerous visitors, you will notice the substantially faster page loading speeds and the less server load. This will happen soon after you begin using the Varnish platform, since it will need some time to cache the content that visitors browse. You can take full advantage of the platform’s capabilities if the websites that are using it use also a dedicated IP, but owing to the fact that your dedicated server comes with a few IP addresses by default, you will not have to pay anything on top of the monthly fee for the machine itself.
