Varnish is a web app accelerator platform, which caches information for quicker access. It is occasionally referred to as a caching HTTP reverse proxy as well and it works between a web server and an Internet browser. When a website visitor accesses a given webpage, the content is requested by the web browser, and then the web server processes this request and delivers the necessary content. If Varnish is enabled for a particular website, it will cache its pages on the very first visit and in case the visitor visits a cached page once again, the content will be delivered by the caching platform instead of the web server. The increased speed is a result of the considerably faster response time that Varnish offers as compared to any server software. At the same time, this does not mean that the users will continue seeing the same content over and over again, as any update on any of the pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Shared Web Hosting

In case you host your sites under a shared web hosting account with us, you’ll be able to activate Varnish with several mouse clicks from your Control Panel. The content caching platform is available as an upgrade with all our plans and you can select the number of the websites that will use it and the total amount of system memory that will be available for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they aren’t tied directly to each other, so you can decide if you want plenty of memory for one large website or less memory for multiple smaller ones. You can unleash the full potential of the Varnish caching platform in case the websites use a dedicated IP address. Using the hosting Control Panel, you can quickly start/restart/remove an instance, delete the cached contents individually for each website which employs the Varnish platform or see an in-depth system log file.

Varnish in Semi-dedicated Servers

The Varnish platform is an essential part of the standard set of services that you will get in case you choose to host your websites under a semi-dedicated server account. You can enable it for any of your Internet sites via our next-generation Hepsia Control Panel. The default memory that the Varnish caching platform can use to cache content is 64 megabytes, but in case you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform at the same time. As these two things are not bound to each other, you can use a couple of websites with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for a single web site. Varnish works best if you get a dedicated IP address for the websites that utilize its power. Hepsia will give you a simple means of rebooting any instance. On top of that, you’ll be able to clear the cached content with only one mouse click.

Varnish in VPS Servers

You can use Varnish with each of our VPS server plans at no extra charge, as the platform is pre-installed and is available by default. The sole requirement is that the virtual machine must be ordered with the Hepsia Control Panel, via which you will be able to set up Varnish for any of your sites with just a few clicks of the mouse. Each Virtual Private Server package offers a different amount of system memory for content caching purposes, but you will have no less than several hundred megabytes, which is quite sufficient even for multiple popular websites. Shortly after you activate Varnish, it’ll begin caching the content that your site visitors browse, so you will notice the significantly faster site load speeds and the reduced load on your virtual machine in no time. The Varnish platform will allow you to use a less high-priced VPS server, as you won’t need that much power to guarantee the correct operation of your websites even if you’ve got popular Internet sites with a lot of visitors. Optimal results are accomplished if the Internet sites that use the Varnish platform also use a dedicated IP address.

Varnish in Dedicated Servers

All dedicated web hosting plans that are ordered with the in-house developed Hepsia website hosting Control Panel feature Varnish, which is among the pre-installed software platforms that you will get with the machine. The Varnish data caching platform can be configured and managed with no effort from the Hepsia Control Panel’s easy-to-navigate interface and, with no more than one mouse click, you can browse an in-depth log, add or reboot an instance, delete the cached files for any site and much more. Shortly after you set up Varnish for a certain domain or sub-domain, it will start caching the web pages requested by the site visitors and once it has cached enough content, you will observe a considerably faster website performance as well as a decreased load on the dedicated server. With Varnish-dedicated memory starting at 3 gigabytes, you will be able to use the platform for workload distribution purposes even if you run an enormous number of sites on the dedicated server.
