Varnish is a web app accelerator, which has been gaining a lot of popularity lately, because it can increase the load speed of any website, at times even by 100%, depending on the content itself. This tool is occasionally called an HTTP reverse proxy as well and is used to reduce the overall load on the physical server and to increase the access speed for the site visitors. Whenever a visitor accesses a page on a certain Internet site, the browser request is handled by the web server and the requested content is returned as a reply. If the Varnish accelerator is activated, it caches the pages that the site visitor opens and if any of them is opened for a second time, it is delivered by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator handles the browser requests substantially faster than any web server, which results in much faster browsing speeds for the site visitors. If any content is updated in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody accesses them.

Varnish in Cloud Hosting

Varnish is offered as an optional upgrade with each and every cloud service and if you would like to use it, you can add it to your website hosting account via the Upgrades menu in your Hepsia hosting Control Panel. There are two different things that can be upgraded – the instances and the memory. The first one pertains to the number of the sites that you want to use Varnish for and the second one, which comes in increments of 32 megabytes, shows the total amount of content that the platform can cache at any particular time. The Hepsia Control Panel’s simple-to-work-with graphical interface will allow you to stop or to reboot any instance, to check elaborate logs or to erase the platform’s cache with just a click. For optimal results, you can employ a dedicated IP address for the Internet sites that will use the platform. With Varnish, your site will open much faster, meaning more happy website users and potential clients.

Varnish in Semi-dedicated Servers

All our Linux semi-dedicated servers include Varnish by default, so you can make full use of the web app accelerator and accelerate the load speed of any site that you host on our platform. You will get 64 MB of system memory dedicated to the Varnish accelerator at no additional charge and you can enable an instance with no more than a few clicks via the Hepsia Control Panel, which is included with the semi-dedicated packages. In case you need more memory, the latter is available in increments of 32 megabytes in the Control Panel’s Upgrades section and it will be at your disposal instantaneously. You can also add more instances as an upgrade, so you can choose if plenty of data will be cached for a single website or if the available memory will be used by several websites. Hepsia will enable you to reboot or to remove any instance, to see the system log file associated with it or to delete the cached content using single-click controls. To get the most out of Varnish, you can set a dedicated IP address for the Internet sites which will use it.

Varnish in VPS Servers

The Varnish content caching platform comes by default with each of the Linux VPS servers that we are offering as long as the virtual server is ordered with the Hepsia hosting Control Panel, so you can improve the overall performance of your websites with just a couple of mouse clicks. The more powerful the package, the more system memory will be available to Varnish, but even with a low-end package, the platform will be able to utilize several hundred megabytes, so even if you own a number of sites, you will notice a considerable reduction in the overall server load and a considerably faster page load speed. The platform will have to work for a little while as the users browse the pages and once the website content has been cached, you’ll distinguish the results. One of the pluses of employing Varnish is that a lower-end and less expensive VPS plan will do the same job as a more expensive one without the caching platform, so not only will your Internet sites work much better, but you will also spare a certain amount of cash.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish platform at no additional charge and you’ll exert complete control over it via a really time and effort saving GUI – you’ll be able to start, to disable or to reboot an instance, to view an exhaustive log, to delete the cached files associated with any website and much, much more. The Varnish caching platform will have several GB of memory at its disposal, so even if you host popular websites with an immense number of visitors, you will notice the significantly faster page loading speeds and the less load on the machine. This will become a fact shortly after you start using Varnish, as it will need a certain amount of time to cache the site content that visitors request. You can take full advantage of the platform’s capacity if the websites that are using it also use a dedicated IP, but since your server comes with a couple of IPs by default, you will not need to pay anything on top of the monthly fee for the machine itself.
