Varnish is a web accelerator, which has been gaining a lot in popularity lately, because it can increase the speed of any Internet site, sometimes even by 100%, depending on the content itself. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the physical machine and to boost the access speed for the site visitors. Each time a visitor accesses a page on a given Internet site, the web browser request is taken care of by the web server and the requested data is sent as a reply. If the Varnish accelerator is activated, it caches the pages that the site visitor browses and if any of them is opened again, it’s fetched by Varnish and not by the web server directly. The increase in the overall performance comes from the fact that the accelerator processes the web requests substantially faster than any web server, which results in much faster browsing speeds for the users. If any data is edited meanwhile, the cached web pages will also be updated the next time somebody attempts to open them.

Varnish in Hosting

You can take advantage of Varnish’s potential and increase your websites’ load speed regardless of the hosting package that you’ve chosen and you can add and configure the platform with a couple of mouse clicks from the easy-to-use interface offered by our leading-edge Hepsia hosting Control Panel. During the process, you will be able to select two separate things – how many Internet sites will employ the Varnish caching platform, i.e. the number of instances, and how much data will be cached, i.e. the amount of system memory. The latter comes in increments of 32 MB and is not tied to the number of instances, so you can use more instances and less memory and the other way around. If you’ve got a lot of content on a certain site and you attract lots of site visitors, more memory will guarantee you a better result. You may also consider using a dedicated IP address for the Internet sites that will use the Varnish caching platform. Hepsia will offer you simple one-click controls for stopping or restarting any instance, for erasing the cache for each Internet site and for checking elaborate logs.

Varnish in Semi-dedicated Hosting

Varnish comes by default with all Linux semi-dedicated hosting packages that we offer and you can use it for workload distribution purposes. It’s available in your Hepsia Control Panel. The Varnish data caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any website that you host in the account. If you are in need of more, you can increase the memory allocation. The memory itself is available in increments of 32 megabytes through the Control Panel’s Upgrades section. The same Upgrades section will enable you to create more instances too, if you want to use Varnish with more Internet sites. The two upgrades can be ordered independently – you can cache the content of one traffic-heavy Internet site or run several Internet sites with the default memory quota. You can get the most out of the Varnish caching platform in case you’ve got a dedicated IP address and you can order one with your semi-dedicated package as well. Hepsia will give you full control over the platform and, with no more than one click, you will be able to clear the cached data, to see a system log file or to restart an instance.

Varnish in VPS

You can take full advantage of the workload balancing capabilities of Varnish with any of our VPS packages if you select Hepsia as your Control Panel. The content caching platform is offered by default and the memory that it’ll be able to use to cache your website content is dependent upon the specific Virtual Private Server plan that you’ve chosen, but even with the lower-end plans, you’ll have at least several hundred megabytes of memory at your disposal exclusively for caching purposes. This amount is sufficient enough to enhance the overall performance of multiple websites. It will take some time for you to distinguish the effects, since Varnish caches the content that visitors request, but shortly thereafter you will notice the significantly reduced load and the enhanced website load speed. The Varnish platform will permit you to use a less powerful VPS package for sites that would usually require a more expensive hosting service.

Varnish in Dedicated Hosting

If you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish platform at no additional charge and you’ll have full control over it via a pretty easy-to-use GUI – you’ll be able to start, to terminate or to reboot an instance, to check an elaborate system log, to delete the cached content associated with any site and much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you manage frequently visited sites with an immense number of visitors, you will notice the substantially faster page loading times and the less load on the server. This will become a fact soon after you begin using the Varnish platform, as it will require some time to cache the pages that people access. You can get the most out of the platform’s capabilities in case the websites that are using it use also a dedicated IP, but owing to the fact that your server comes with a few IPs by default, you will not have to pay anything on top of the monthly fee for the machine itself.
