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 100%, based on the content. This tool is sometimes referred to as a caching 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. Anytime a visitor accesses a page on a certain website, the web browser request is taken care of by the web server and the requested information is sent as a response. If the Varnish accelerator is activated, it caches the pages that the visitor opens and if any of them is loaded once more, it is delivered by Varnish and not by the server directly. The increase in the overall performance is due to the fact that the accelerator handles the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the users. If any data is modified in the meantime, the cached webpages will also be updated the next time someone attempts to access them.

Varnish in Cloud Hosting

In case you host your sites in a cloud hosting account with us, you will be able to activate Varnish with a few mouse clicks from your hosting Control Panel. The platform is offered as an optional upgrade with all our shared packages and you can choose how many websites will use it and the maximum storage space that will be used for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they are not directly linked to each other, so you can choose if you need lots of memory for a single large-sized site or less memory for several smaller ones. You can take advantage of the full potential of the Varnish caching platform in case the websites use a dedicated IP. With the hosting Control Panel, you can effortlessly start/restart/cancel an instance, clear the cached content independently for each website which uses the Varnish platform or view an exhaustive system log.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is an essential part of the standard set of services that you’ll obtain when you choose to host your websites in a semi-dedicated server account. You can activate it for any of your sites via our advanced Hepsia hosting Control Panel. The default amount of memory that the Varnish caching platform can use to cache content is 64 MB, but in case you decide that you need more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this platform simultaneously. Since these two features are not tied to each other, you can use several sites with the default memory or you can get more memory in increments of 32 MB and use all of it for one single Internet site. The Varnish platform performs best when you set a dedicated IP for the sites that utilize its power. The Hepsia Control Panel will provide you with a simple way of restarting any instance. On top of that, you’ll be able to delete the cached files with only one click.

Varnish in VPS Servers

You can take full advantage of the load balancing potential of Varnish with all our VPS servers if you select Hepsia as your web hosting Control Panel. The platform comes by default and the amount of system memory that it’ll be able to utilize to cache the content of your websites is dependent on the given Virtual Private Server plan that you’ve selected, but even with the lower-end plans, you will have no less than several hundred megabytes of memory at your disposal solely for data caching purposes. This amount is enough to improve the work of numerous sites. It will take a little time for you to detect the effects, as the Varnish platform caches the content that website visitors access, but after that you’ll notice the considerably lowered load on your VPS and the enhanced site load speed. Varnish will allow you to use a less powerful plan for websites which would typically require a more expensive web hosting service.

Varnish in Dedicated Servers

All dedicated servers which are ordered with the custom-built Hepsia web hosting Control Panel include Varnish, which is one of the pre-installed software platforms that you will get with the dedicated machine. The Varnish platform can be activated and managed with ease from Hepsia’s intuitive GUI and, with no more than one click of the mouse, you can check an in-depth log, create or restart an instance, delete the cached files associated with any site and much more. Soon after you enable Varnish for a given domain or subdomain, it will begin caching the webpages accessed by the website visitors and once it has cached enough web content, you’ll witness a tremendously faster website performance as well as a reduced server load. With Varnish-dedicated memory starting at three gigabytes, you’ll be able to use the platform for workload distribution purposes even if you host multiple Internet sites on the machine.
