Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, because it can increase the loading speed of any site, sometimes even by one hundred percent, depending on the content. This tool is sometimes called an HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to increase the browsing speed for the site visitors. Each time a visitor loads a page on a particular site, the web browser request is processed by the web server and the requested data is delivered as a response. If Varnish is enabled, it caches the web pages that the site visitor browses and if any of them is accessed for a second time, it is fetched by Varnish and not by the server directly. The performance boost is due to the fact that the accelerator processes the browser requests substantially quicker than any web server, which results in much faster browsing speeds for the visitors. In case any data is edited in the meantime, the cached pages will also be updated the next time somebody opens them.

Varnish in Cloud Hosting

You can take advantage of Varnish’s potential and improve your sites’ speed regardless of the cloud hosting plan that you have selected and you can activate and configure the platform with several clicks of the mouse through the simple-to-work-with interface offered by our leading-edge Hepsia Control Panel. During the process, you will be able to choose two different things – how many sites will employ Varnish, i.e. the number of instances, and how much content will be cached, in other words – the amount of system memory. The latter is offered in increments of 32 MB and is not bound to the number of instances, so you can order more instances with less memory and vice versa. If you’ve got a lot of content on a particular site and you gain a lot of site visitors, more memory will give you a better result. You may also consider using a dedicated IP address for the sites that will use the Varnish platform. Hepsia will offer you simple one-click buttons for terminating or restarting any instance, for deleting the cache for any Internet site and for seeing detailed system logs.

Varnish in Semi-dedicated Servers

All our Linux semi-dedicated servers include Varnish by default, so you can make full use of the web accelerator tool and accelerate the loading speed of any website that you host on our semi-dedicated servers. You will get 64 megabytes of memory exclusively for Varnish at no additional cost and you will be able to enable an instance with no more than a few clicks of the mouse via the Hepsia hosting Control Panel, which comes with the semi-dedicated plans. If you need more memory, the latter is offered in increments of 32 megabytes in the Upgrades section of the Control Panel and it will be available to you instantaneously. You can also add more instances as an upgrade, so you can decide whether plenty of data will be cached for a single website or whether the available memory will be utilized by different Internet sites. Hepsia will allow you to restart or to remove any instance, to check the system log file for it or to delete the cached content using single-click buttons. To get the most out of the Varnish accelerator, you can allocate a dedicated IP to the sites which will use it.

Varnish in VPS Servers

You can use Varnish with any of our VPS server packages at no extra charge, since the platform is pre-installed and is available by default. The sole prerequisite is that the virtual machine must come with the Hepsia hosting Control Panel, through which you will be able to set up Varnish for any of your Internet sites with just a few clicks. Each Virtual Private Server plan includes a different amount of memory for caching purposes, but you will get at least several hundred MB, which is sufficient enough even for multiple traffic-hungry websites. Soon after you activate the Varnish platform, it will begin caching the content that your website visitors request, so you’ll notice the much better page load times and the reduced load on your server in no time. Varnish will allow you to use a less costly virtual server, since you will not need that much power to warrant the uninterrupted operation of your sites even if you own busy sites with multiple visitors. Maximum results are accomplished if the Internet sites that use the Varnish caching platform use also a dedicated IP address.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain Varnish at no additional charge and you will exert total control over it via an amazingly simple-to-navigate GUI – you will be able to start, to remove or to restart an instance, to browse an in-depth log, to clear the cached data associated with any Internet site and much more. Varnish will have several GB of virtual memory at its disposal, so even if you’ve got popular websites with many visitors, you will notice the significantly better page loading times and the reduced load on the dedicated machine. This will become a fact soon after you begin using the Varnish platform, as it will need a certain amount of time to cache the web pages that people open. You can get the most out of the platform’s capacity if the sites that are using it also use a dedicated IP address, but due to the fact that your server includes several IPs by default, you won’t need to pay anything on top of the monthly charge for the server itself.
