Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any website, at times even by 100 percent, depending 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 physical machine and to accelerate the browsing speed for the site visitors. Every time a visitor loads a page on a given Internet site, the web browser request is taken care of by the web server and the requested information is sent as a reply. If the Varnish accelerator is activated, it caches the web pages that the visitor browses and in case any of them is opened again, it’s served by Varnish and not by the server directly. The performance boost comes from the fact that the accelerator processes the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is updated meanwhile, the cached web pages will also be ‘refreshed’ the next time someone opens them.

Varnish in Shared Hosting

You can take advantage of Varnish’s full potential and boost your sites’ speed regardless of the shared hosting package that you have chosen and you can add and configure the content caching platform with a couple of mouse clicks using the easy-to-use graphical interface offered by our next-gen Hepsia hosting Control Panel. In the meantime, you will be able to select two separate things – how many websites will use Varnish, i.e. the number of instances, and how much information will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not bound to the number of instances, so you can order more instances and less memory and vice versa. If you have plenty of content on a certain website and you win numerous site visitors, more memory will guarantee you a better result. You may also consider using a dedicated IP for the websites that will use the Varnish caching platform. Hepsia will provide you with easy one-click buttons for cancelling or rebooting any instance, for deleting the cache for each website and for viewing detailed logs.

Varnish in Semi-dedicated Servers

The semi-dedicated plans that we’re offering will permit you to employ Varnish as soon as your brand new semi-dedicated server account has been set up, as the content caching 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 launched. In case you need more system memory, you can add 32 MB at a time from the Hepsia Control Panel’s Upgrades section and it will be allocated to your semi-dedicated server immediately. You can also increase the number of the Internet sites that employ Varnish, or the so-called ‘instances’, which are not bound directly to the amount of memory that you use, which suggests that you will have more flexibility. The platform will immensely lower the load produced by your sites, so your website visitors can enjoy fast-opening web pages. You’ll be able to manage the Varnish platform with no effort via your Control Panel using quick-access buttons. You will be able to start/cancel any of the instances that you’ve got, to delete the cache for any of your Internet sites or to see system log files.

Varnish in VPS Servers

We provide Varnish with all of the Hepsia-managed VPS plans, so if you buy a server with this Control Panel, you will be able to make use of the content caching platform at no extra charge. Varnish can use different amounts of memory for content caching purposes based on the particular Virtual Private Server package that you have selected at signup, but in any case, this amount won’t be less than several hundred megabytes. This is quite enough to boost the overall performance of several regularly visited Internet sites, so the better site browsing speeds and the reduced load on your virtual machine will be perceptible. The effect may not be distinguishable right away, as the Varnish platform will require some time to cache the content that users access, but soon after you activate it, you’ll witness its full capacity. This caching platform will allow you to use a lower-end VPS server and to pay less money to get the exact same performance you’d get with a higher-end virtual machine without Varnish.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish content caching platform at no extra charge and you will have complete control over it via a pretty easy-to-navigate graphical interface – you will be able to start, to stop or to reboot an instance, to see a detailed system log, to delete the cached data associated with any website and much, much more. Varnish will have several GB of system memory at its disposal, so even if you manage large-scale sites with numerous visitors, you will notice the much faster website load speeds and the less load on the server. This will become a fact shortly after you start using Varnish, as it will require a certain amount of time to cache the site content that people open. You can make the most of the platform’s capability in case the sites that are using it also use a dedicated IP address, but considering the fact that your dedicated server comes with a couple of IPs by default, you will not have to pay anything on top of your monthly charge for the server itself.
