Varnish is a web app accelerator platform, which caches information for the sake of quicker response times. It is sometimes called a caching HTTP reverse proxy too and it interacts between a web server and a web browser. When a visitor loads a specific web page, the content is requested by the Internet browser, and then the server processes this browser request and returns the necessary content. If Varnish is enabled for a specific site, it will cache the pages at the first request and in case the visitor opens a cached page again, the data will be delivered by the caching platform and not by the server. The accelerated speed is an end result of the significantly faster response speed that the Varnish platform offers as compared to any web server software. Of course, this does not mean that the website visitors will continue being served the very same content again and again, because any change on any of the pages is reflected in the content that Varnish saves in its system memory.

Varnish in Cloud Hosting

If you host your Internet sites under a cloud hosting account with us, you’ll be able to add Varnish with a few clicks of the mouse via your hosting Control Panel. The platform comes as an optional upgrade with all our shared plans and you can select how many websites will use it and the maximum amount of system memory that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they’re not linked directly to each other, so you can choose whether you need lots of memory for one single large-sized site or less memory for several smaller ones. You can use the full potential of Varnish in case the websites use a dedicated IP. Using the hosting Control Panel, you can easily start/reboot/remove an instance, clear the cached files individually for each site which uses the Varnish platform or see an exhaustive log.

Varnish in Semi-dedicated Servers

The semi-dedicated plans offered by us will permit you to employ Varnish once your new semi-dedicated account has been activated, as the caching platform is offered by default. 64 MB of system memory will be assigned to Varnish the moment your account is enabled, so you can make use of this load distribution software once your website has been published online. In case you need more memory, you can add 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated machine in a flash. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not directly tied to the amount of memory that you use, which suggests that you will have more versatility. The Varnish platform will greatly decrease the load on the semi-dedicated machine generated by your sites, so your website visitors can enjoy fast-loading web pages. You’ll be able to manage the Varnish caching platform with no effort through the Control Panel using fast-access controls. You’ll be able to start/delete any of the instances that you’ve got, to delete the cached data for any of your sites or to see system logs.

Varnish in Dedicated Servers

You can employ Varnish to increase the loading speed of any site that’s hosted on a dedicated server with us if the Hepsia hosting Control Panel is installed on it. Not only will you get the content caching platform ready for use at no extra cost, but you’ll also have total control over it through Hepsia’s simple-to-navigate graphical interface. It will take just one single click of the mouse to start or delete an instance or to delete the cached files for any Internet site that is using the Varnish platform and in case you are more advanced, you can also check the platform’s system logs. Varnish comes with at least 3 GB of virtual memory for website content caching purposes, so even if you run an immense number of Internet sites on your dedicated server and they all use the Varnish caching platform, the improvement in their overall performance will be noticeable. You’ll simply need to wait for a while till Varnish caches whatever pages the site visitors load on their end. The platform works best when the websites use a dedicated IP address, but due to the fact that our dedicated servers include 3 charge-free IP addresses, you will have everything you need.
