Varnish is a web accelerator platform, which caches information for the sake of faster access. It’s sometimes called a caching HTTP reverse proxy as well and it works between a web server and an Internet browser. When a site visitor loads a particular page, its content is requested by the web browser, and then the web server processes this request and sends back the necessary information. If Varnish is enabled for a specific site, it will cache its pages at the very first request and if the user visits a cached page for a second time, the information will be delivered by the accelerator platform instead of the server. The boosted load speed is an end result of the considerably faster response time that the Varnish platform offers compared with any web server software. At the same time, this does not mean that the users will keep seeing the exact same content over and over again, as any change on any of the web pages is reflected in the content that the Varnish platform saves in its system memory.

Varnish in Shared Hosting

In case you host your Internet sites in a shared hosting account with us, you will be able to activate Varnish with a couple of clicks of the mouse from your hosting Control Panel. The content caching platform comes as an optional upgrade with all our hosting plans and you can choose the number of the sites that will use it and the maximum storage space that will be used for the cached data. The two upgradeable features in the Control Panel’s Upgrades section 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 need plenty of memory for one large-size site or less memory for several smaller ones. You can unlock the full potential of Varnish if the websites use a dedicated IP. With the hosting Control Panel, you can swiftly start/restart/shut down an instance, clear the cached contents independently for each website that uses Varnish or view a detailed log.

Varnish in Semi-dedicated Hosting

The Varnish caching platform is an essential part of the default set of services that you’ll obtain when you choose to host your Internet sites in a semi-dedicated server account. You can set it up for any of your websites through our innovative Hepsia hosting Control Panel. The default amount of memory that Varnish can use to cache data is 64 megabytes, but if you decide that you need 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 Internet sites that can use this caching platform at the same time. Since these two things are not linked to each other, you can use a couple of websites with the default amount of memory or you can order more memory in increments of 32 MB and use all of it for a single web site. The Varnish platform performs best when you allocate a dedicated IP address to the Internet sites that utilize its power. The Hepsia Control Panel will give you a simple way of restarting any instance. Furthermore, you’ll be able to clear the cached contents with just one single click.

Varnish in VPS Hosting

You can use the load balancing potential of Varnish with each of our Linux VPS hosting if you select Hepsia as your hosting Control Panel. The Varnish content caching platform is available by default and the amount of memory that it’ll be able to utilize to cache your website content depends on the given Virtual Private Server plan that you’ve selected, but even with the lower-end packages, you will have no less than several hundred MB of system memory at your disposal solely for data caching purposes. This amount is enough to optimize the performance of multiple sites. It will take some time for you to distinguish the effects, as Varnish caches the content that visitors request, but soon after that you will notice the considerably decreased load on your VPS and the accelerated Internet site load speed. The Varnish caching platform will allow you to make use of a less powerful Virtual Private Server plan for sites which would normally need a more expensive web hosting solution.

Varnish in Dedicated Web Hosting

All Linux dedicated web hosting which are ordered with the custom-built Hepsia hosting Control Panel include Varnish, which is among the pre-installed software platforms that you will get with the dedicated machine. The Varnish caching platform can be activated and administered without efforts through the Hepsia Control Panel’s easy-to-use graphical interface and, with no more than one click, you can see an in-depth log, add or reboot an instance, delete the cached files associated with any site and much, much more. Shortly after you configure Varnish for a particular domain or subdomain, it will begin caching the pages opened by your website visitors and as soon as it has cached enough content, you’ll witness a considerably better website performance plus a decreased load on your dedicated machine. With Varnish-dedicated system memory starting at 3 GB, you’ll be able to use the platform for load distribution purposes even if you run an immense number of sites on your machine.
