Varnish is a web app accelerator platform, which caches content for the sake of faster access. It’s sometimes called a caching HTTP reverse proxy too and it interacts between a web server and its users. When a site visitor loads a certain webpage, the content is requested by the Internet browser, and then the server handles this request and delivers the requested content. If Varnish is activated for a specific website, it will cache its pages at the very first request and in case the user accesses a cached page for a second time, the information will be delivered by the accelerator platform instead of the web server. The increased speed is an end result of the substantially faster response time that the Varnish platform offers compared with any web server software. Of course, this does not mean that the visitors will keep seeing the same content over and over again, since any update on any of the web pages is reflected in the content that Varnish keeps in its memory.

Varnish in Web Hosting

If you host your websites in a web hosting account with our company, you’ll be able to add Varnish with several clicks of the mouse via your Control Panel. The content caching platform is available as an upgrade with all our plans and you can choose the number of the websites that will use it and the maximum amount of system memory that will be available for the cached data. 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 tied to each other, so you can decide if you need plenty of memory for a single large-size site or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform if the sites use a dedicated IP address. Using the hosting Control Panel, you can quickly start/restart/cancel an instance, delete the cached content individually for each website which employs the Varnish platform or see a comprehensive log file.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is part of the default service set that you will get when you decide to host your sites in a semi-dedicated server account. You can set it up for any of your websites via our advanced Hepsia Control Panel. The default memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. 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 a few websites with the default memory or you can add more memory in increments of 32 MB and use all of it for one single site. Varnish performs best when you set a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will give you a simple means of rebooting any instance. What’s more, you’ll be able to clear the cached contents with just one click.

Varnish in Dedicated Servers Hosting

When you need a more powerful web hosting solution and you purchase any of the Linux dedicated servers hosting packages that we offer, you’ll be able to use the Varnish content caching platform to improve the performance of your websites at no additional charge as long as the dedicated server is ordered with our advanced Hepsia hosting Control Panel. Its simple-to-use interface will allow you to monitor platform processes, to clear the cached contents or to restart any instance with one click of the mouse. The smallest amount of memory that the Varnish platform can use to cache content is 3 GB, which is more than enough for an immense number of regularly visited sites, so your dedicated server will be able to handle a gigantic load while your visitors are having a smooth browsing experience. As your dedicated machine will come with several different dedicated IP addresses, you will be able to make use of Varnish’s full capacity.
