Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, as it can increase the speed of any website, at times even by 100%, based on the content. This tool is occasionally called a caching HTTP reverse proxy as well and is used to decrease the overall load on the physical server and to improve the access speed for the site visitors. Whenever a visitor accesses a page on a certain site, the browser request is taken care of by the web server and the requested info is served as a reply. If Varnish is enabled, it caches the web pages that the site visitor browses and in case any of them is accessed again, it’s fetched by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator processes the browser requests considerably quicker than any web server, which results in much faster browsing speeds for the site visitors. In case any data is updated in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody opens them.

Varnish in Shared Hosting

In case you host your Internet sites under a shared hosting account with our company, you’ll be able to activate Varnish with several clicks through your hosting Control Panel. The data caching platform is offered as an optional upgrade with all our packages and you can select how many websites will use it and the total amount of system memory that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they’re not linked directly to each other, so you can choose whether you need plenty of memory for one single large-size website or less memory for several smaller ones. You can unleash the full potential of the Varnish caching platform in case the websites use a dedicated IP address. With the hosting Control Panel, you can quickly start/restart/remove an instance, clear the cached data individually for each site that employs Varnish or see a detailed log file.

Varnish in Semi-dedicated Hosting

The Linux semi-dedicated hosting offered by our company will permit you to use Varnish once your brand new semi-dedicated server account is active, since the caching platform comes by default. 64 megabytes of system memory will be assigned to Varnish the second your account is enabled, so you can take advantage of this load distribution software as soon as your site has been launched online. If you’re in need of 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 instantly. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not bound directly to the amount of memory that you use, which means that you’ll have more freedom. The Varnish caching platform will considerably lower the load generated by your sites, so your visitors can enjoy fast-opening pages. You will be able to manage the Varnish platform effortlessly through your Hepsia Control Panel using quick-access buttons. You will be able to start/delete any of the instances that you’ve got, to delete the cached data for any of your sites or to check system log files.

Varnish in VPS Web Hosting

You can take advantage of Varnish with all our virtual private server packages at no extra cost, since the data caching platform is pre-installed and is included by default. The sole condition is that the VPS server must come with the Hepsia hosting Control Panel, via which you’ll be able to activate Varnish for any of your websites with just a couple of clicks. Each package features a different amount of system memory for data caching purposes, but you will have at least several hundred MB, which is enough even for multiple traffic-heavy sites. Shortly after you enable Varnish, it’ll begin caching the content that your website visitors browse, so you’ll notice the much faster website loading times and the lowered load on the virtual machine very soon. Varnish will allow you to use a less expensive Virtual Private Server, since you won’t need that many resources to guarantee the proper operation of your Internet sites even if you run resource-intensive sites with a lot of visitors. Maximum results are accomplished if the sites which use Varnish use also a dedicated IP.

Varnish in Dedicated Servers Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish caching platform at no additional charge and you will exert total control over it via an extremely user-friendly interface – you’ll be able to start, to stop or to restart an instance, to see a detailed system log, to clear the cached data associated with any website and much, much more. The Varnish platform will have several gigabytes of virtual memory at its disposal, so even if you run large-size websites with a large number of visitors, you will notice the substantially better website loading speeds and the less load on the dedicated server. This will become a fact soon after you begin using the Varnish platform, as it will need some time to cache the pages that visitors request. You can get the most out of the platform’s capability in case the websites that are using it also use a dedicated IP address, but considering the fact that your dedicated server comes with a couple of IP addresses by default, you won’t need to pay anything on top of your monthly charge for the server itself.
