Varnish is a web app accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any site, sometimes even by 100%, depending on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to reduce the overall load on the server and to increase the access speed for the website visitors. Each time a visitor opens a page on a particular Internet site, the browser request is handled by the web server and the requested content is returned as a response. If Varnish is activated, it caches the pages that the visitor opens and if any of them is opened for a second time, it’s served by Varnish and not by the web server directly. The boost in the performance comes from the fact that the accelerator handles the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is changed in the meantime, the cached web pages will also be updated the next time somebody tries to open them.

Varnish in Shared Website Hosting

If you host your sites in a shared website hosting account with us, you’ll be able to add Varnish with a few clicks of the mouse via your hosting Control Panel. The caching platform is available as an upgrade with all our shared plans and you can choose the number of the websites that will use it and the total amount of system memory that will be used for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they’re not tied directly to each other, so you can choose if you want plenty of memory for a single large site or less memory for several smaller ones. You can unleash the full potential of the Varnish caching platform in case the websites use a dedicated IP address. With the Control Panel, you can easily start/restart/stop an instance, clear the cached data individually for each website that uses Varnish or see an in-depth log.

Varnish in Semi-dedicated Hosting

The Varnish platform is part of the standard set of services that you will receive when you choose to host your sites in a semi-dedicated server account. You can set it up for any of your sites via our next-gen Hepsia Control Panel. The default system memory that the Varnish platform can use to cache data is 64 megabytes, but if you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this platform simultaneously. As these two things are not linked to each other, you can use several websites with the default amount of 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 works best when you allocate a dedicated IP to the sites that utilize its power. The Hepsia Control Panel will offer you a simple means of restarting any instance. In addition, you’ll be able to delete the cached contents with just one click.

Varnish in VPS Hosting

You can take full advantage of the load balancing potential of Varnish with each of our Linux VPS hosting if you choose Hepsia as your web hosting Control Panel. The Varnish data caching platform comes by default and the amount of system memory that it’ll be able to use to cache your website content depends on the particular Virtual Private Server package that you’ve picked, but even with the less powerful plans, you will have no less than several hundred MB of system memory at your disposal exclusively for data caching purposes. This amount is sufficient to improve the performance of multiple sites. It’ll take a little time for you to notice the results, since Varnish caches the content that visitors access, but soon thereafter you’ll notice the substantially decreased load on the VPS server and the accelerated Internet site loading speed. The Varnish caching platform will permit you to use a lower-end VPS package for websites which would typically need a more costly hosting solution.

Varnish in Dedicated Web Hosting

All Linux dedicated web hosting that are ordered with the in-house built Hepsia hosting Control Panel include Varnish, which is one of the pre-installed software platforms that you will get with the server. The Varnish content caching platform can be activated and managed without efforts via Hepsia’s simple-to-work-with interface and, with no more than one mouse click, you can see an exhaustive log, add or restart an instance, clear the cached data for any site and much more. Shortly after you enable Varnish for a particular domain or sub-domain, it will begin caching the webpages accessed by your website visitors and as soon as it has cached enough web content, you’ll observe a significantly faster website performance in addition to a lowered load on your server. With Varnish-dedicated memory starting at 3 GB, you will be able to use the platform for workload distribution purposes even if you run multiple sites on your machine.
