Varnish is a website accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the speed of any website, at times even by 100%, depending on the content itself. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the physical server and to increase the browsing speed for the site visitors. Every time a visitor opens a page on a specific website, the browser request is processed by the web server and the requested info is returned as a response. If Varnish is enabled, it caches the web pages that the site visitor browses and if any of them is loaded once more, it is served by Varnish and not by the web server directly. The performance improvement comes from the fact that the accelerator handles the browser requests considerably faster than any web server, which leads to much faster browsing speeds for the visitors. In case any data is edited in the meantime, the cached webpages will also be ‘refreshed’ the next time someone attempts to access them.
Varnish in Cloud Hosting
You can unlock Varnish’s potential and improve the load speed of your sites regardless of the cloud hosting package that you have chosen and you can add and configure the content caching platform with a few mouse clicks using the simple-to-work-with GUI offered by our next-gen Hepsia hosting Control Panel. In the meantime, you’ll be able to select two different things – how many websites will employ Varnish, in other words – the number of instances, and how much content will be cached, in other words – the amount of memory. The latter comes in increments of 32 megabytes and is not linked to the number of instances, so you can order more instances and less memory and vice versa. In case you have lots of content on a particular website and you win plenty of site visitors, more memory will give you better results. You may also consider using a dedicated IP address for the Internet sites that will use Varnish. The Hepsia Control Panel will offer you easy one-click controls for terminating or restarting any instance, for erasing the cache associated with each website and for checking comprehensive logs.
Varnish in Semi-dedicated Servers
The semi-dedicated servers offered by us will allow you to employ Varnish as soon as your brand new account has been created, as the platform is offered by default. 64 MB of system memory will be allocated to Varnish the second your account is enabled, so you can make use of this load balancing software once your site has been published on the Internet. In case you need more system memory, you can get 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be allocated to your semi-dedicated machine right away. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not directly linked to the amount of memory that you use, which means that you will enjoy more versatility. The Varnish platform will significantly reduce the load on the semi-dedicated server generated by your sites, so your visitors can enjoy fast-loading pages. You will be able to manage the Varnish caching platform with no effort through the Control Panel using fast-access controls. You’ll be able to start/discontinue any of the instances that you’ve got, to delete the cache associated with any of your websites or to view system log files.
Varnish in VPS Servers
We offer Varnish with all of the Hepsia-managed VPS servers, so if you buy a VPS with this hosting Control Panel, you will be able to take advantage of the caching platform at no additional cost. Varnish can use different amounts of system memory for content caching purposes based on the particular sever setup that you have chosen during the registration process, but at any rate, this amount won’t be less than several hundred megabytes. This is quite enough to improve the overall performance of a number of frequently visited Internet sites, so the faster website load speeds and the decreased load on your virtual machine will be noticeable. The result may not be obvious instantly, since the Varnish platform will need some time to cache the site content that people open, but shortly after you enable it, you’ll observe its full capacity. This platform will permit you to use a less powerful VPS server and to give less cash to get the very same performance you’d get with a higher-end machine without Varnish.
Varnish in Dedicated Servers
When you need a powerful website hosting solution and you buy one of the dedicated servers that we offer, you’ll be able to use the Varnish data caching platform to improve the work of your Internet sites at no extra charge on the condition that the server is ordered with our cutting-edge Hepsia Control Panel. Its easy-to-use interface will allow you to keep an eye on platform processes, to clear the cached data or to restart any instance with a click. The minimum amount of memory that the Varnish platform can employ to cache site content is 3 GB, which is quite enough for an enormous collection of heavy sites, so your dedicated server will be able to cope with a gigantic load while your visitors are having a seamless browsing experience. Since your dedicated machine will come with a number of dedicated IP addresses, you will be able to use Varnish’s maximum capacity.
