Varnish is a web accelerator tool, which has been gaining a lot in popularity lately, as it can increase the speed of any website, sometimes even by 100 percent, depending on the content itself. This tool is sometimes called an HTTP reverse proxy as well and is used to lower the overall server load and to accelerate the access speed for the website visitors. Each time a visitor loads a page on a given website, the web browser request is processed by the web server and the requested data is returned as a reply. If the Varnish accelerator is activated, it caches the web pages that the site visitor browses and in case any of them is opened again, it’s delivered by Varnish and not by the web server directly. The performance boost comes from the fact that the accelerator handles the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is changed meanwhile, the cached pages will also be ‘refreshed’ the next time somebody attempts to access them.

Varnish in Shared Hosting

You can take advantage of Varnish’s potential and enhance the loading speed of your websites irrespective of the shared hosting package that you’ve selected and you can activate and configure the content caching platform with several mouse clicks via the intuitive interface offered by our innovative Hepsia hosting Control Panel. In the meantime, you’ll be able to select two different things – how many Internet sites will employ Varnish, i.e. the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter is offered in increments of 32 MB and is not linked to the number of instances, so you can use more instances with less memory and the other way around. In case you’ve got lots of content on a specific website and you gain lots of visitors, more memory will guarantee you a better result. You may also consider using a dedicated IP for the Internet sites that will use the Varnish caching platform. Hepsia will offer you simple one-click controls for deleting or rebooting any instance, for erasing the cache for each Internet site and for checking in-depth system logs.

Varnish in Semi-dedicated Servers

Varnish is a feature, which comes as standard with all semi-dedicated servers that we are offering and you can use it for workload distribution purposes. It is available in your Hepsia hosting Control Panel. The content caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any Internet site that you host in the semi-dedicated account. If you are in need of more than that, you can increase the system memory quota. The memory itself is available in increments of 32 megabytes in the Upgrades section of the Control Panel. The same Upgrades section will permit you to create more instances too, in case you’d like to use Varnish with multiple sites. The two upgrades can be added independently – you can cache the content of one resource-hungry Internet site or use several different Internet sites with the default memory allocation. You can take full advantage of the Varnish caching platform if you’ve got a dedicated IP address and you can order one with your semi-dedicated server package as well. Hepsia will grant you complete control over the platform and, with no more than one click, you will be able to clear the cache, to view a system log or to restart an instance.

Varnish in VPS Servers

We offer Varnish with all Hepsia-equipped VPS servers, so in case you order a VPS with this hosting Control Panel, you will be able to make the most of the data caching platform at no additional fee. The Varnish platform can utilize different amounts of memory for data caching purposes depending on the very setup that you’ve chosen during the registration process, but nevertheless, this amount will not be less than several hundred megabytes. This is quite enough to optimize the performance of a handful of resource-demanding sites, so the faster site loading speeds and the reduced load on your virtual server will be noticeable. The effect may not be visible momentarily, as Varnish will require some time to cache the website content that people open, but soon after you enable it, you will feel its full capacity. This caching platform will permit you to use a less powerful VPS server and to give less money to get the very same performance you’d get with a higher-end machine without Varnish.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish platform at no additional fee and you’ll exert complete control over it through a rather simple-to-work-with graphical interface – you will be able to start, to deactivate or to restart an instance, to check a detailed log, to clear the cached data associated with any website and much more. The Varnish platform will have several GB of memory at its disposal, so even if you host traffic-heavy Internet sites with a vast number of visitors, you’ll notice the considerably better website loading speeds and the decreased load. This will happen soon after you begin using the Varnish platform, as it will need a certain amount of time to cache the content that users request. You can take full advantage of the platform’s capability if the Internet sites that are using it also use a dedicated IP, but since your server comes with a couple of IPs by default, you won’t have to pay anything on top of the monthly charge for the server itself.
