Varnish is a web application accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the speed of any Internet site, at times even by 100%, depending on the content. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to lower the overall load on the physical machine and to accelerate the access speed for the site visitors. Anytime a visitor opens a page on a particular site, the browser request is processed by the web server and the requested data is sent as a response. If the Varnish accelerator is enabled, it caches the pages that the visitor opens and if any of them is loaded again, it’s delivered by Varnish and not by the web server directly. The improvement in the performance comes from the fact that the accelerator handles the browser requests significantly quicker than any web server, which leads to much faster browsing speeds for the users. If any content is changed meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody attempts to open them.

Varnish in Shared Hosting

Varnish is available as an optional upgrade with all our shared hosting. You can add it to your hosting account through the Hepsia hosting Control Panel, which comes with all shared hosting packages and you’ll get a pretty easy-to-use graphical interface, which will give you complete control over the content caching platform. Using one-click quick-access controls, you can reboot or cancel any of the instances, i.e. Varnish will no longer be activated for a particular website. You can also view a detailed system log or erase the cache associated with any of the Internet sites. When you add Varnish to your shared web hosting plan, you will be able to choose the maximum amount of system memory that will be available to you for data caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for top performance, you can set a dedicated IP for the websites that will use Varnish. This will allow you to get the most out of your websites and to have a lot of gratified website visitors.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is included in the basic service set that you’ll obtain in case you choose to host your Internet sites under a semi-dedicated server account. You can activate it for any of your Internet sites through our next-generation Hepsia hosting Control Panel. The default memory that Varnish can use to cache data is 64 MB, but if you decide that you want more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. Since these two things are not linked to each other, you can use a few Internet sites with the default memory or you can add more memory in increments of 32 MB and use all of it for one single Internet site. Varnish works best if you assign a dedicated IP address to the Internet sites that utilize its power. Hepsia will provide you with a simple way of restarting any instance. Also, you’ll be able to delete the cached contents with only one click.

Varnish in VPS Servers

You can use Varnish with all our VPS server plans at no extra fee, since the data caching platform is pre-installed and is included by default. The sole prerequisite is that the VPS server must come with the Hepsia Control Panel, through which you will be able to set up Varnish for any of your Internet sites with just a few mouse clicks. Each VPS plan offers a different amount of system memory for caching purposes, but you will have minimum several hundred MB, which is enough even for several frequently visited sites. Shortly after you set up Varnish, it will begin caching the content that your website visitors open, so you’ll notice the considerably faster webpage load times and the reduced load on your virtual server very soon. The platform will permit you to use a less pricey virtual machine, as you won’t need that many resources to guarantee the correct operation of your Internet sites even if you’ve got resource-demanding websites with lots of visitors. Maximum results are accomplished if the Internet sites which use Varnish also use a dedicated IP.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you’ll obtain the Varnish platform at no extra cost and you will exert complete control over it via an amazingly easy-to-use interface – you will be able to start, to discontinue or to restart an instance, to see an in-depth system log, to clear the cached files associated with any site and much, much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you own popular sites with a large number of visitors, you’ll notice the substantially faster website loading times and the lowered load on your dedicated machine. This will become a fact shortly after you start using Varnish, since it will require a certain amount of time to cache the site content that people browse. You can get the most out of the platform’s capability if the sites that are using it use also a dedicated IP, but considering the fact that your server includes several IP addresses by default, you will not have to pay anything on top of your monthly charge for the machine itself.
