Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, as it can increase the speed of any site, at times even by 100 percent, based on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to decrease the overall server load and to improve 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 information is sent as a reply. If the Varnish accelerator is enabled, it caches the web pages that the site visitor browses and in case any of them is opened again, it is served by Varnish and not by the web server directly. The performance improvement is due to the fact that the accelerator handles 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 edited meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody attempts to access them.

Varnish in Cloud Hosting

You can take advantage of Varnish’s potential and improve the load speed of your websites regardless of the cloud hosting plan that you have selected and you can enable and set up the content caching platform with a few clicks of the mouse via the user-friendly interface offered by our next-generation Hepsia Control Panel. During the procedure, 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 info will be cached, i.e. 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 order more instances with less memory and the other way around. If you have plenty of content on a particular site and you draw a lot of site visitors, more system memory will give you better results. You may also consider using a dedicated IP address for the Internet sites that will use the Varnish platform. Hepsia will provide you with easy 1-click buttons for disabling or rebooting any instance, for deleting the cache associated with any Internet site and for checking exhaustive logs.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is an essential part of the default set of services that you will receive in case you choose to host your sites under a semi-dedicated server account. You can enable it for any of your Internet sites via our next-gen Hepsia hosting Control Panel. The default amount of memory that Varnish can use to cache content is 64 megabytes, but if you decide that you want more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. 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 features are not linked to each other, you can use several Internet sites with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for one single Internet site. Varnish performs best if you set a dedicated IP address for the Internet sites that utilize its power. The Hepsia Control Panel will provide you with a simple means of rebooting any instance. Also, you’ll be able to delete the cached contents with only a click.

Varnish in VPS

You can use the load balancing capabilities of Varnish with any of our VPS when you select Hepsia as your web hosting Control Panel. The content caching platform comes by default and the system memory that it will be able to use to cache the content of your websites is dependent upon the given 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 only for caching purposes. This amount is sufficient to optimize the overall performance of numerous websites. It will take a little time for you to observe the effects, as Varnish caches the content that visitors access, but shortly after that you will notice the significantly decreased load on your VPS server and the enhanced site loading speed. Varnish will permit you to use a lower-end Virtual Private Server package for Internet sites which would usually require a more high-priced hosting solution.

Varnish in Dedicated Hosting

All Linux dedicated hosting that are ordered with the in-house built Hepsia website hosting Control Panel include Varnish, which is one of the pre-installed platforms that you’ll get with the dedicated machine. The Varnish platform can be configured and administered without effort via the Hepsia Control Panel’s time and effort saving GUI and, with no more than one mouse click, you can check a detailed system log, create or restart an instance, clear the cached files for any Internet site and much more. Shortly after you configure the Varnish platform for a certain domain or sub-domain, it will start caching the pages opened by your visitors and once it has cached enough content, you’ll perceive a tremendously faster website performance plus a lowered load on the dedicated machine. With Varnish-dedicated memory starting at 3 gigabytes, you’ll be able to use the platform for load balancing purposes even if you run numerous Internet sites on the server.
