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 site, at times even by 100 percent, depending on the content itself. This tool is occasionally referred to as an HTTP reverse proxy too and is used to decrease the overall load on the physical server and to increase the access speed for the site visitors. Every time a visitor loads a page on a specific site, the browser request is handled by the web server and the requested content is returned as a reply. If Varnish is activated, it caches the pages that the site visitor browses and in case any of them is loaded for a second time, it is fetched 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 considerably quicker than any web server, which results in much faster browsing speeds for the users. If any data is modified in the meantime, the cached pages will also be updated the next time someone accesses them.
Varnish in Shared Web Hosting
If you host your websites in a shared web hosting account with us, you’ll be able to activate Varnish with a couple of clicks from your Control Panel. The data caching platform is offered as an upgrade with all our shared web hosting packages and you can select the number of the sites that will use it and the total amount of system memory that will be used for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they are not linked directly to each other, so you can decide whether you want a lot of memory for one large-sized site or less memory for multiple smaller ones. You can make use of the full potential of the Varnish platform if the websites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/deactivate an instance, clear the cached files independently for each website which employs the Varnish platform or check a detailed system log.
Varnish in Semi-dedicated Servers
All our Linux semi-dedicated hosting service include Varnish by default, so you can make use of the web accelerator and enhance the speed of any website that you host on our semi-dedicated servers. You will get 64 megabytes of system memory exclusively for the Varnish accelerator at no additional fee and you’ll be able to enable an instance with no more than a couple of mouse clicks via the Hepsia Control Panel, which comes with the semi-dedicated plans. 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 available to you immediately. You can also order more instances as a separate upgrade, so you can choose if lots of content will be cached for a single website or if the memory will be utilized by different websites. The Hepsia Control Panel will permit you to restart or to delete any instance, to view the system log file for it or to delete the cached files using one-click controls. To get the most out of Varnish, you can get a dedicated IP address for the Internet sites which will use it.
Varnish in VPS Servers
We offer Varnish with all of the Hepsia-managed VPS service, so in case you acquire a server with this Control Panel, you’ll be able to make the most of the caching platform at no extra charge. The Varnish platform can utilize different amounts of system memory for content caching purposes based on the specific setup that you have picked during the signup process, but nevertheless, this amount won’t be less than several hundred megabytes. This is quite enough to boost the work of a number of traffic-intensive Internet sites, so the better web page load speeds and the reduced load on the VPS will be perceivable. The result may not be obvious right away, as the Varnish platform will require a certain amount of time to cache the website content that visitors browse, but soon after you activate it, you will feel its full capacity. This platform will permit you to use a lower-end Virtual Private Server and to give less money to get the exact same performance you would get with a more powerful machine without Varnish.

Varnish will have several gigabytes of memory at its disposal, so even if you own large-sized websites with a large number of visitors, you will notice the considerably better web page load speeds and the less load on the dedicated machine. This will become a fact shortly after you begin using Varnish, since it will require some time to cache the site content that users browse. You can make the most of the platform’s potential if the sites that are using it also use a dedicated IP, but since your dedicated server includes a few IP addresses by default, you won’t have to pay anything on top of the monthly fee for the server itself.
