Varnish is a web app accelerator, which has been gaining a lot in popularity in recent years, as it can increase the speed of any website, at times even by 100%, based 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 increase the browsing speed for the website visitors. Every time a visitor loads a page on a certain site, the browser request is taken care of by the web server and the requested content is served as a response. If Varnish is activated, it caches the web pages that the visitor opens and if any of them is accessed once more, it is delivered by Varnish and not by the web server directly. The increase in the overall performance is due to the fact that the accelerator processes the web requests significantly quicker than any web server, which results in much faster browsing speeds for the users. In case any content is modified in the meantime, the cached webpages will also be updated the next time someone attempts to access them.

Varnish in Web Hosting

We offer Varnish as an optional upgrade with each and every Linux web hosting and if you’d like to use it, you can add it to your account using the Upgrades menu in your Hepsia hosting Control Panel. There’re two separate features that can be upgraded – the number of instances and the system memory. The first one pertains to the number of the websites that you wish to use Varnish for and the second one, which is offered in increments of 32 MB, shows the total amount of content that the content caching platform can store at any particular moment. Hepsia’s intuitive graphical interface will allow you to terminate or to reboot any instance, to view detailed logs or to delete the platform’s cache with just a click. For best results, you can employ a dedicated IP address for the Internet sites that will use the platform. With Varnish, your site will open tremendously faster, meaning more satisfied visitors and potential clients.

Varnish in Semi-dedicated Servers

All our semi-dedicated servers come with Varnish by default, so you can use the web accelerator and improve the load speed of any website that you host on our platform. You will get 64 megabytes of system memory exclusively for the Varnish accelerator at no extra charge and you’ll be able to enable an instance with no more than a few clicks through the Hepsia Control Panel, which is included with the semi-dedicated server packages. If you want more memory, the latter is offered in increments of 32 MB through the Control Panel’s Upgrades section and it will be at your disposal right away. You can also add more instances as an upgrade, so you can choose whether a lot of content will be cached for one site or if the memory will be used by several websites. Hepsia will permit you to restart or to shut down any instance, to check the system log file associated with it or to delete the cached files using 1-click controls. To get the most out of the Varnish accelerator, you can set a dedicated IP address for the sites that will use it.

Varnish in VPS Servers

You can use Varnish with each of our VPS server plans at no extra charge, since the caching platform is pre-installed and is included by default. The sole condition is that the VPS must be ordered with the Hepsia Control Panel, through which you will be able to activate Varnish for any of your Internet sites with just a few mouse clicks. Each Virtual Private Server plan offers a different amount of memory for caching purposes, but you’ll have at least several hundred MB, which is enough even for several busy websites. Shortly after you activate Varnish, it will begin caching the content that your visitors request, so you will notice the much better Internet site loading times and the less load on the server very soon. Varnish will allow you to use a less pricey Virtual Private Server, since you will not need that much power to sustain the proper operation of your sites even if you’ve got large-sized sites with multiple visitors. Maximum results are achieved if the websites which use the Varnish caching platform also use a dedicated IP address.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain the Varnish data caching platform at no additional cost and you’ll exert full control over it through an amazingly simple-to-navigate graphical interface – you will be able to start, to stop or to restart an instance, to view a detailed system log, to delete the cached files associated with any Internet site and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you host traffic-consuming websites with plenty of visitors, you’ll notice the significantly faster site loading speeds and the reduced load on the machine. This will happen shortly after you start using the Varnish platform, as it will need a certain amount of time to cache the pages that visitors open. You can get the most out of the platform’s potential if the sites that are using it use also a dedicated IP, but since your dedicated server comes with a couple of IP addresses by default, you won’t have to pay anything on top of the monthly charge for the machine itself.
