Varnish is a web accelerator, which has been gaining a lot of popularity lately, as it can increase the load speed of any site, at times even by 100 percent, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to reduce the overall load on the physical server and to accelerate the browsing speed for the site visitors. Anytime a visitor opens a page on a given Internet site, the browser request is processed by the web server and the requested data is sent as a response. If Varnish is activated, it caches the pages that the site visitor browses and if any of them is opened once again, it’s delivered by Varnish and not by the web server directly. The boost in the overall performance is due to the fact that the accelerator handles the web requests significantly quicker than any web server, which results in much faster browsing speeds for the visitors. If any data is updated in the meantime, the cached webpages will also be updated the next time somebody accesses them.

Varnish in Cloud Hosting

Varnish is offered as an optional upgrade with all our cloud hosting. You can add it to your account through the Hepsia hosting Control Panel, which comes with all shared packages and you will get a rather simple-to-use GUI, which will grant you complete control over the data caching system. Using 1-click quick-access controls, you can reboot or delete any of the instances, in other words – Varnish will no longer be activated for a specific website. You can also see a comprehensive system log file or clear the cache associated with any of the Internet sites. When you add Varnish to your shared web hosting package, you will be able to select the maximum amount of memory that will be at your disposal for content 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 optimal performance, you can get a dedicated IP for the websites that will use Varnish. This will permit you to take full advantage of your sites and to have a lot of pleased website visitors.

Varnish in Semi-dedicated Servers

The Varnish platform is included in the default set of services that you’ll receive if you choose to host your websites under a semi-dedicated server account. You can enable it for any of your websites through our advanced Hepsia hosting Control Panel. The default amount of system memory that Varnish can use to cache content is 64 megabytes, but in case you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform simultaneously. Since these two things are not linked to each other, you can use several Internet sites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for one single web site. The Varnish platform performs best if you get a dedicated IP address for the Internet sites that utilize its power. The Hepsia Control Panel will give you a simple way of restarting any instance. On top of that, you will be able to clear the cached content with only one click.

Varnish in VPS Servers

We provide Varnish with all Hepsia-equipped VPS servers, so if you get a VPS with this Control Panel, you will be able to make the most of the data caching platform at no extra charge. Varnish can utilize different amounts of memory for content caching purposes depending on the specific Virtual Private Server package that you’ve selected on the order page, but in any case, this amount won’t be less than several hundred megabytes. This is more than enough to boost the work of a handful of large-scale sites, so the faster website browsing speeds and the reduced load on your VPS server will be perceptible. The result may not be observable right away, as Varnish will require some time to cache the content that people browse, but shortly after you set it up, you will feel its full potential. This platform will permit you to use a less powerful VPS server and to give less money to get the same performance you would get with a higher-end machine without Varnish.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you will get the Varnish caching platform at no additional charge and you’ll exert complete control over it via a quite time and effort saving graphical interface – you will be able to start, to disable or to reboot an instance, to check a detailed log, to clear the cached content for any website and much more. The Varnish caching platform will have several gigabytes of virtual memory at its disposal, so even if you own resource-demanding sites with an enormous number of visitors, you will notice the tremendously better page loading times and the less load on the dedicated machine. This will happen shortly after you start using Varnish, since it will require some time to cache the web pages that users open. You can take full advantage of the platform’s capabilities if the Internet sites that are using it also use a dedicated IP address, but owing to the fact that your server comes with several IPs by default, you will not have to pay anything on top of your monthly fee for the machine itself.
