Varnish is a website accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, at times even by one hundred percent, based on the content. This tool is sometimes called a caching HTTP reverse proxy as well and is used to decrease the overall load on the server and to accelerate the browsing speed for the site visitors. Whenever a visitor opens a page on a particular site, the browser request is processed by the web server and the requested info is returned as a reply. If Varnish is activated, it caches the pages that the site visitor browses and if any of them is opened again, it’s served by Varnish and not by the server directly. The increase in the performance is due to the fact that the accelerator handles the web requests significantly quicker than any web server, which results in much faster browsing speeds for the users. If any data is modified meanwhile, the cached pages will also be ‘refreshed’ the next time somebody attempts to open them.
Varnish in Web Hosting
You can take advantage of Varnish’s potential and boost your sites’ speed irrespective of the web hosting plan that you’ve selected and you can enable and set up the content caching platform with several clicks via the easy-to-work-with graphical interface offered by our next-generation Hepsia hosting Control Panel. During the process, you’ll be able to choose two separate things – how many Internet 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 offered in increments of 32 MB and is not linked to the number of instances, so you can add more instances with less memory and vice versa. If you’ve got lots of content on a certain site and you get lots of site visitors, more system memory will give you a better result. You may also consider employing a dedicated IP for the Internet sites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with simple one-click controls for shutting down or restarting any instance, for clearing the cache associated with each site and for viewing comprehensive logs.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers come with Varnish by default, so you can take full advantage of the web application accelerator tool and enhance the loading speed of any website that you host on our semi-dedicated servers. You will get 64 megabytes of system memory dedicated to Varnish at no extra fee and you’ll be able to add an instance with no more than a few mouse clicks through the Hepsia hosting Control Panel, which comes with the semi-dedicated plans. If you want more memory, the latter is offered in increments of 32 MB in the Upgrades section of the Control Panel and it will be available to you instantly. You can also add more instances as an upgrade, so you can choose if plenty of content will be cached for a single site or whether the memory will be used by different sites. Hepsia will permit you to reboot or to cancel any instance, to see the system log file for it or to clear the cached files using 1-click controls. To take full advantage of the Varnish accelerator, you can allocate a dedicated IP to the websites that will employ it.
Varnish in VPS Servers
You can use the workload balancing capabilities of Varnish with any of our VPS servers if you choose Hepsia as your Control Panel. The caching platform is available by default and the system memory that it’ll be able to use to cache the content of your sites is dependent upon the given Virtual Private Server plan that you have chosen, but even with the lower-end packages, you’ll have no less than several hundred MB of memory at your disposal solely for content caching purposes. This amount is sufficient to enhance the work of multiple sites. It will take some time for you to observe the results, as the Varnish platform caches the content that visitors request, but soon after that you will notice the substantially less load on the Virtual Private Server and the accelerated Internet site browsing speed. The Varnish caching platform will allow you to make use of a lower-end Virtual Private Server plan for sites which would typically need a more expensive hosting service.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you’ll obtain the Varnish data caching platform at no extra cost and you’ll exert total control over it through an incredibly easy-to-navigate GUI – you will be able to start, to cancel or to restart an instance, to check an in-depth system log, to delete the cache for any website and much, much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you run resource-heavy sites with an immense number of visitors, you will notice the much faster site loading speeds and the lowered load. This will happen shortly after you begin using the Varnish platform, as it will need a certain amount of time to cache the content that people browse. You can make the most of the platform’s capabilities in case the websites that are using it also use a dedicated IP address, but since your server includes a few IP addresses by default, you won’t have to pay anything on top of your monthly charge for the server itself.
