Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, because it can increase the load speed of any site, at times even by 100%, depending on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to accelerate the browsing speed for the site visitors. Whenever a visitor loads a page on a certain Internet site, the web browser request is taken care of by the web server and the requested content is sent as a response. If the Varnish accelerator is enabled, it caches the pages that the visitor browses and in case any of them is loaded once more, it’s served 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 significantly faster than any web server, which leads to much faster browsing speeds for the users. In case any content is edited in the meantime, the cached pages will also be ‘refreshed’ the next time somebody attempts to access them.

Varnish in Shared Hosting

You can use Varnish’s potential and enhance your sites’ load speed regardless of the shared hosting package that you’ve selected and you can activate and configure the data caching platform with several mouse clicks from the simple-to-use GUI offered by our cutting-edge Hepsia hosting Control Panel. In the meantime, you will be able to choose two separate things – how many sites will employ the Varnish platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can order more instances with less memory and vice versa. In case you have lots of content on a given Internet site and you draw plenty of site visitors, more system memory will give 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 provide you with easy 1-click controls for deactivating or rebooting any instance, for clearing the cache associated with each website and for checking exhaustive logs.

Varnish in Semi-dedicated Servers

The semi-dedicated servers that we’re offering will permit you to use Varnish once your brand-new account has been set up, as the data caching platform comes by default. 64 MB of system memory will be assigned to Varnish the moment your account is enabled, so you can use this workload balancing software once your website has been published to the web. If you’re in need of more memory, you can get 32 MB at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be allocated to your semi-dedicated machine right away. You can also increase the number of the sites that employ Varnish, or the so-called ‘instances’, which are not directly bound to the amount of system memory that you use, which goes to say that you will have more flexibility. The Varnish caching platform will immensely decrease the load on the server produced by your websites, so your site visitors can enjoy fast-opening web pages. You will be able to manage the Varnish caching platform with no effort through your Control Panel using fast-access buttons. You will be able to start/cancel any of the instances that you’ve got, to delete the cached content associated with any of your sites or to see system log files.

Varnish in VPS Servers

You can use the workload balancing potential of Varnish with any of our VPS servers if you pick Hepsia as your Control Panel. The content caching platform comes by default and the system memory that it’ll be able to utilize to cache your website content depends upon the given VPS plan that you have picked, but even with the lower-end plans, you will have no less than several hundred megabytes of system memory at your disposal solely for content caching purposes. This amount is sufficient enough to boost the overall performance of numerous websites. It will take a little time for you to observe the results, as Varnish caches the content that website visitors browse, but shortly after that you will notice the considerably reduced load on your VPS server and the accelerated Internet site loading speed. The Varnish platform will allow you to make use of a less powerful VPS package for websites which would usually require a more pricey hosting solution.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you will get Varnish at no extra fee and you will exert total control over it via a very simple-to-work-with GUI – you’ll be able to start, to remove or to reboot an instance, to view a comprehensive system log, to clear the cached data associated with any site and much more. The Varnish caching platform will have several GB of memory at its disposal, so even if you’ve got large-scale sites with plenty of visitors, you’ll notice the significantly better website loading times and the less server load. This will become a fact shortly after you begin using the Varnish platform, since it will need a certain amount of time to cache the web pages that people browse. You can get the most out of the platform’s capacity if the Internet sites that are using it use also a dedicated IP address, but owing to the fact that your dedicated server includes a few IPs by default, you won’t have to pay anything on top of your monthly fee for the machine itself.
