Varnish is a content caching platform, which is sometimes referred to as a caching HTTP reverse proxy. It’s a web accelerator tool that can accelerate the speed of a website by up to 1000 percent, based on the content itself. Each time a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor opens it again. Thus, the browser request from the visitor is not handled by the server and the web page will load substantially faster, as the Varnish platform can deliver content many times faster than any server software. The result is a significantly faster loading website, which leads to an immensely improved visitor experience. When any of the cached pages is updated on the live website, the data that Varnish keeps in its memory is updated too, so the users will not see outdated info.

Varnish in Shared Hosting

You can make use of Varnish’s full potential and increase the speed of your sites regardless of the shared hosting plan that you’ve selected and you can activate and configure the data caching platform with several clicks of the mouse using the user-friendly interface offered by our innovative Hepsia hosting Control Panel. During the process, you’ll be able to choose two different things – how many sites will employ the Varnish caching platform, in other words – the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter is offered in increments of 32 megabytes and is not linked to the number of instances, so you can use more instances with less memory and the other way around. In case you have a lot of content on a certain site and you receive a lot of visitors, more memory will guarantee you better results. You may also consider employing a dedicated IP for the sites that will use the Varnish caching platform. Hepsia will provide you with simple 1-click buttons for turning off or rebooting any instance, for clearing the cache associated with any Internet site and for checking detailed system logs.

Varnish in Semi-dedicated Hosting

Varnish is included in the basic set of services that you will receive in case you decide to host your websites in a semi-dedicated server account. You can enable it for any of your Internet sites via our next-generation Hepsia Control Panel. The default amount of system memory that Varnish can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform at the same time. As these two features aren’t tied to each other, you can use a few sites with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for a single site. The Varnish platform works best if you use a dedicated IP address for the sites that utilize its power. Hepsia will give you a simple way of restarting any instance. In addition, you will be able to clear the cached contents with only one single click of the mouse.

Varnish in Dedicated Servers Hosting

If you order a dedicated server with the Hepsia hosting Control Panel, you will obtain Varnish at no additional cost and you will have full control over it through an extremely easy-to-work-with graphical interface – you will be able to start, to delete or to restart an instance, to check an exhaustive log, to clear the cached files associated with any website and much more. The Varnish platform will have several GB of virtual memory at its disposal, so even if you host resource-consuming sites with a huge number of visitors, you’ll notice the much better site load times and the decreased load. This will become a fact soon after you start using the Varnish platform, as it will require some time to cache the web pages that people browse. You can get the most out of the platform’s capacity if the Internet sites that are using it use also a dedicated IP, but since your dedicated server includes several IP addresses by default, you won’t have to pay anything on top of the monthly fee for the server itself.
