Varnish is a web application accelerator platform, which caches info for faster access. It’s sometimes called an HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor accesses a given webpage, its content is requested by the browser, and then the server handles this request and delivers the required information. If Varnish is enabled for a website, it will cache its pages at the first request and in case the visitor opens a cached page once again, the information will be delivered by the caching platform and not by the server. The increased loading speed is a result of the significantly faster response time that the Varnish platform offers compared to any server software. Of course, this does not mean that the site visitors will continue being served the exact same content over and over again, as any modification on any of the pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Website Hosting
You can make use of Varnish’s potential and enhance the loading speed of your websites regardless of the website hosting package that you have picked and you can enable and configure the platform with several clicks through the easy-to-work-with interface offered by our cutting-edge Hepsia Control Panel. During the procedure, you’ll be able to select two separate things – how many sites will employ the Varnish caching platform, i.e. the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter is available in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances with less memory and the other way around. If you have lots of content on a particular site and you get many site visitors, more system memory will give you a better result. You may also consider employing a dedicated IP for the Internet sites that will use Varnish. The Hepsia Control Panel will provide you with easy 1-click buttons for switching off or rebooting any instance, for erasing the cache for each website and for viewing exhaustive system logs.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated services come with Varnish by default, so you can make use of the web app accelerator and optimize the loading speed of any site that you host on our platform. You will get 64 megabytes of system memory particularly for the Varnish accelerator at no extra fee and you will be able to add an instance with no more than a few clicks via the Hepsia hosting Control Panel, which is included with the semi-dedicated server plans. In case you want more memory, the latter is available in increments of 32 MB through the Upgrades section of the Control Panel and it will be available to you instantly. You can also add more instances as an upgrade, so you can decide whether plenty of content will be cached for a single site or if the memory will be utilized by different Internet sites. The Hepsia Control Panel will permit you to restart or to remove any instance, to see the system log for it or to clear the cached data using single-click buttons. To get the most out of Varnish, you can allocate a dedicated IP to the websites which will employ it.
Varnish in VPS Hosting
You can take full advantage of the workload balancing potential of Varnish with all our VPS hosting in case you pick Hepsia as your web hosting Control Panel. The data caching platform is available by default and the amount of memory that it will be able to utilize to cache your website content depends upon the particular Virtual Private Server plan that you’ve selected, but even with the less powerful packages, you’ll have no less than several hundred MB of system memory at your disposal exclusively for content caching purposes. This amount is sufficient enough to improve the performance of multiple sites. It will take a little time for you to see the results, since the Varnish platform caches the content that website visitors open, but soon thereafter you will notice the substantially less load on the server and the enhanced website load speed. Varnish will permit you to use a lower-end VPS plan for websites that would typically need a more expensive web hosting service.
Varnish in Dedicated Web Hosting
In case you order a dedicated server with the Hepsia Control Panel, you will get the Varnish data caching platform at no additional cost and you will exert total control over it through a really easy-to-navigate interface – you’ll be able to start, to disable or to restart an instance, to view an exhaustive system log, to clear the cached files associated with any Internet site and much, much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you have large-scale websites with a huge number of visitors, you’ll notice the tremendously better web page load speeds and the less load on your dedicated machine. This will become a fact shortly after you start using Varnish, as it will require a certain amount of time to cache the content that users open. You can get the most out of the platform’s capacity in case the sites that are using it also use a dedicated IP, but since your server includes several IP addresses by default, you won’t need to pay anything on top of the monthly fee for the machine itself.
