Varnish is a data caching platform, which is occasionally called an HTTP reverse proxy. It’s a website accelerator tool that can increase the load speed of a website by up to 1000%, depending on the content itself. Every 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 in case the visitor opens it again. In this way, the web browser request from the visitor is not processed by the server and the web page will open considerably faster, since Varnish can deliver content many times faster than any server software. The result will be a substantially faster loading website, which leads to a much-improved browsing experience. When any of the cached webpages is updated on the actual Internet site, the information that Varnish saves in its system memory is updated as well, so the visitors will never see outdated data.

Varnish in Shared Hosting

In case you host your Internet sites in a shared hosting account with us, you’ll be able to activate Varnish with a few clicks via your hosting Control Panel. The data caching platform comes as an upgrade with all our web hosting plans and you can select the number of the sites that will use it and the maximum storage space that will be available for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they’re not linked directly to each other, so you can choose whether you want lots of memory for one single large-size site or less memory for multiple smaller ones. You can unlock the full potential of Varnish if the sites use a dedicated IP address. Using the Control Panel, you can swiftly start/restart/disable an instance, delete the cached content individually for each website that uses the Varnish platform or view a detailed log.

Varnish in Semi-dedicated Hosting

The Varnish platform is part of the basic set of services that you will receive if you choose to host your Internet sites in a semi-dedicated server account. You can activate it for any of your Internet sites through our avant-garde Hepsia hosting Control Panel. The default amount of memory that the Varnish platform can use to cache content is 64 megabytes, but in case you decide that you want 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 simultaneously. Since these two features are not linked to each other, you can use several instances with the default memory or you can order more memory in increments of 32 megabytes and use all of it for one single Internet site. The Varnish caching platform performs best if you assign a dedicated IP address to the websites that utilize its power. The Hepsia Control Panel will offer you a simple way of rebooting any instance. Furthermore, you’ll be able to delete the cached content with only a click.

Varnish in Dedicated Servers Hosting

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain the Varnish data caching platform at no additional fee and you will exert complete control over it through a rather intuitive GUI – you’ll be able to start, to stop or to restart an instance, to browse a comprehensive system log, to delete the cached data associated with any Internet site and much more. The Varnish platform will have several GB of virtual memory at its disposal, so even if you run resource-absorbing Internet sites with an immense number of visitors, you will notice the much faster website loading times and the decreased load on your dedicated machine. This will happen soon after you begin using the Varnish platform, since it will need a certain amount of time to cache the website content that people browse. You can make the most of the platform’s capability if the sites that are using it use also a dedicated IP, but owing to the fact that your server comes with a few IP addresses by default, you won’t need to pay anything on top of your monthly fee for the server itself.
