Varnish is a web application accelerator, which has been gaining a lot of popularity lately, as it can increase the load speed of any Internet site, at times even by one hundred percent, 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 improve the access speed for the site visitors. Every time a visitor accesses a page on a specific Internet site, the web browser request is handled by the web server and the requested content is returned as a reply. If the Varnish accelerator is enabled, it caches the web pages that the site visitor opens and in case any of them is accessed once again, it is served by Varnish and not by the server directly. The improvement in the overall performance comes from the fact that the accelerator handles the browser requests considerably quicker than any web server, which leads to much faster browsing speeds for the site visitors. If any data is updated in the meantime, the cached webpages will also be updated the next time somebody opens them.
Varnish in Website Hosting
You can unleash Varnish’s full potential and improve your websites’ loading speed irrespective of the website hosting package that you’ve chosen and you can add and configure the content caching platform with a couple of clicks using the easy-to-use interface offered by our next-generation Hepsia hosting Control Panel. During the procedure, you’ll be able to choose two different things – how many Internet sites will use the Varnish caching platform, in other words – the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter is offered in increments of 32 MB and is not linked to the number of instances, so you can use more instances with less memory and vice versa. If you’ve got plenty of content on a certain website and you get lots of website visitors, more memory will guarantee you better results. You may also consider using a dedicated IP address for the sites that will use the Varnish caching platform. Hepsia will provide you with simple one-click buttons for terminating or rebooting any instance, for erasing the cache associated with each Internet site and for seeing detailed logs.
Varnish in Semi-dedicated Servers
Varnish comes by default with all Linux semi-dedicated hosting service offered by our company and you can use it for workload balancing purposes. It’s available in your Hepsia Control Panel. The Varnish content caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can use it with any Internet site that you host in your semi-dedicated account. In case you need more, you can increase the memory allowance. The memory itself is available in increments of 32 megabytes through the Upgrades section of the Control Panel. The same Upgrades section will enable you to create more instances as well, in case you wish to use Varnish with more Internet sites. The two upgrades can be added separately – you can cache the content of a single resource-absorbing site or run a number of sites with the default memory allocation. You can take full advantage of the Varnish caching platform in case you use a dedicated IP and you can get one with your semi-dedicated package as well. The Hepsia Control Panel will grant you complete control over the caching platform and, with no more than one click, you will be able to delete the cached contents, to check a log or to restart an instance.
Varnish in VPS Servers
You can take advantage of Varnish with any of our VPS server packages at no extra charge, since the caching platform is pre-installed and is included by default. The one and only precondition is that the virtual server must be ordered with the Hepsia hosting Control Panel, through which you will be able to set up Varnish for any of your sites with only a couple of mouse clicks. Each VPS package includes a different amount of system memory for content caching purposes, but you will have no less than several hundred megabytes, which is quite sufficient even for multiple busy sites. Soon after you enable the Varnish platform, it will start caching the content that your website visitors browse, so you will notice the significantly better page loading times and the less load on your VPS server very soon. The caching platform will permit you to use a less expensive VPS server, as you won’t need that many resources to warrant the proper operation of your sites even if you’ve got traffic-hungry sites with plenty of visitors. Optimal results are achieved if the websites that use the Varnish platform also use a dedicated IP.
Varnish in Dedicated Servers
When you want a powerful hosting solution and you obtain one of the Linux dedicated service that we offer, you can use the Varnish platform to improve the overall performance of your Internet sites at no extra fee on the condition that the dedicated server is ordered with our advanced Hepsia Control Panel. Its simple-to-navigate interface will permit you to keep an eye on platform processes, to clear the cache or to reboot any instance with one single mouse click.

Since your server will include several different dedicated IPs, you will be able to use Varnish’s maximum capacity.
