Varnish is a web application accelerator, which has been gaining a lot in popularity lately, because it can increase the loading speed of any site, sometimes even by 100%, depending on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to decrease the overall server load and to improve the access speed for the site visitors. Whenever a visitor loads a page on a specific Internet site, the browser request is handled by the web server and the requested information is returned as a reply. If Varnish is activated, it caches the web pages that the site visitor browses and in case any of them is opened once again, it’s fetched by Varnish and not by the server directly. The boost in the overall performance 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 site visitors. In case any data is modified meanwhile, the cached web pages will also be updated the next time somebody attempts to access them.

Varnish in Shared Hosting

You can unlock Varnish’s full potential and improve the speed of your websites regardless of the shared hosting plan that you’ve chosen and you can add and set up the data caching platform with a couple of clicks using the simple-to-work-with GUI offered by our cutting-edge Hepsia Control Panel. During the process, you’ll 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 information 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 add more instances and less memory and the other way around. If you’ve got plenty of content on a specific Internet site and you attract plenty of site visitors, more memory will guarantee you better results. You may also consider employing a dedicated IP address for the websites that will use the Varnish platform. Hepsia will provide you with easy 1-click buttons for deleting or restarting any instance, for deleting the cache for each website and for checking detailed logs.

Varnish in Semi-dedicated Servers

Varnish is an essential part of the default service set that you’ll acquire in case you decide to host your sites in a semi-dedicated server account. You can set it up for any of your websites through our innovative Hepsia Control Panel. The default amount of system memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform at the same time. As these two things are not linked to each other, you can use a few sites with the default memory or you can order more memory in increments of 32 megabytes and use all of it for a single web site. The Varnish platform performs best if you use a dedicated IP for the sites that utilize its power. Hepsia will provide you with a simple way of rebooting any instance. In addition, you’ll be able to delete the cached contents with just one single click.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish caching platform at no additional cost and you’ll have complete control over it via a rather easy-to-work-with GUI – you’ll be able to start, to remove or to restart an instance, to check an exhaustive log, to delete the cached content associated with any site and much more. The Varnish platform will have several gigabytes of virtual memory at its disposal, so even if you run resource-intensive Internet sites with many visitors, you’ll notice the significantly better site load speeds and the less load on the dedicated machine. This will become a fact shortly after you start using Varnish, as it will need a certain amount of time to cache the site content that people access. You can take full advantage of the platform’s capacity in case the sites that are using it also use a dedicated IP, but owing to the fact that your server includes several IPs by default, you won’t have to pay anything on top of your monthly charge for the server itself.
