Varnish is a web accelerator platform, which caches information for the sake of faster access. It’s occasionally referred to as a caching HTTP reverse proxy too and it interacts between a web server and a web browser. When a site visitor opens a particular webpage, the content is requested by the browser, and then the server handles this request and sends back the needed info. If Varnish is enabled for a website, it will cache the pages on the very first request and in case the visitor visits a cached page for a second time, the data will be delivered by the accelerator platform instead of the web server. The improved speed is a result of the considerably faster response speed that Varnish offers as compared to any server software. At the same time, this doesn’t mean that the website visitors will continue being served the exact same content again and again, because any modification on any of the web pages is reflected in the content that Varnish caches in its memory.

Varnish in Cloud Website Hosting

If you host your sites in a cloud website hosting account with us, you’ll be able to add Varnish with a couple of clicks from your hosting Control Panel. The caching platform comes as an optional upgrade with all our shared web hosting packages and you can choose how many websites will use it and the total amount of system memory that will be used for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they aren’t linked directly to each other, so you can choose if you want a lot of memory for a single large-scale site or less memory for multiple smaller ones. You can make use of the full potential of Varnish in case the sites use a dedicated IP address. Using the hosting Control Panel, you can quickly start/reboot/shut down an instance, clear the cached content individually for each site which uses the Varnish platform or view an in-depth system log file.

Varnish in Semi-dedicated Servers

The Varnish platform is part of the basic set of services that you will acquire in case you decide to host your Internet sites under a semi-dedicated server account. You can configure it for any of your websites through our next-gen Hepsia hosting Control Panel. The default amount of system memory that the Varnish platform can use to cache data is 64 MB, but in case 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, in other words – the number of the websites that can use this caching platform simultaneously. As these two features are not bound to each other, you can use several instances with the default memory or you can add more memory in increments of 32 megabytes and use all of it for a single web site. The Varnish caching platform works best if you assign a dedicated IP address to the websites that utilize its power. Hepsia will give you an easy means of rebooting any instance. Also, you’ll be able to clear the cached data with just one click.

Varnish in Dedicated Servers

You can employ Varnish to boost the load speed of any website that is hosted on a dedicated server from us if the Hepsia Control Panel is pre-installed on it. Not only will you get the caching platform ready for use at no extra cost, but you’ll also have complete control over it via the Hepsia Control Panel’s simple-to-navigate GUI. It’ll take only one mouse click to start or remove an instance or to clear the cached files for any site that’s using the Varnish platform and in case you’re more competent, you can also see the platform’s logs. Varnish comes with no less than three gigabytes of virtual memory for site content caching purposes, so even in case you host a vast number of websites on your dedicated machine and they all use the platform, the difference in their performance will be noticeable. You’ll only need to wait for a little while till Varnish caches whatever webpages the website visitors access on their end. The platform works best when the websites use a dedicated IP, but considering the fact that our dedicated servers include 3 cost-free IPs, you will have everything you need.
