Varnish is a data caching platform, which is occasionally called a caching HTTP reverse proxy. It is a web application accelerator tool that can increase the load speed of a site by up to 1000 percent, depending 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 if the visitor opens it again. Thus, the browser request from the visitor is not handled by the web server and the page will load significantly faster, as Varnish can serve information many times faster than any server software. The result is a much faster loading site, which leads to a greatly improved browsing experience. In case any of the cached web pages is updated on the actual website, the content that Varnish keeps in its system memory is ‘refreshed’ as well, so the users won’t end up seeing old data.
Varnish in Shared Hosting
You can unlock Varnish’s potential and increase the speed of your sites irrespective of the shared hosting package that you’ve picked and you can enable and set up the content caching platform with a few mouse clicks via the simple-to-work-with GUI offered by our next-gen Hepsia hosting Control Panel. In the meantime, you’ll be able to choose two different things – how many sites will use Varnish, i.e. the number of instances, and how much data will be cached, i.e. the amount of system memory. The latter comes in increments of 32 MB and is not linked to the number of instances, so you can order more instances with less memory and the other way around. In case you’ve got lots of content on a specific Internet site and you get plenty of site visitors, more memory will give you better results. You may also consider employing a dedicated IP for the websites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with easy one-click controls for turning off or rebooting any instance, for deleting the cache associated with any website and for viewing exhaustive logs.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated packages include Varnish by default, so you can make full use of the web accelerator and optimize the load speed of any site that you host on our platform. You’ll get 64 MB of system memory exclusively for Varnish at no additional charge and you will be able to add an instance with no more than a couple of clicks via the Hepsia hosting Control Panel, which comes with the semi-dedicated server plans. If you want more memory, the latter is offered in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be available to you immediately. You can also add more instances as an upgrade, so you can decide whether lots of data will be cached for one site or if the memory will be used by different sites. Hepsia will allow you to reboot or to deactivate any instance, to check the system log file associated with it or to delete the cached content using 1-click buttons. To take full advantage of the Varnish accelerator, you can set a dedicated IP address for the websites that will employ it.
Varnish in Dedicated Hosting
If you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish content caching platform at no additional charge and you’ll exert complete control over it through a rather simple-to-navigate graphical interface – you will be able to start, to discontinue or to reboot an instance, to see an exhaustive log, to delete the cached files for any website and much, much more. The Varnish caching platform will have several gigabytes of memory at its disposal, so even if you’ve got resource-requiring Internet sites with a lot of visitors, you will notice the significantly faster website load times and the decreased load on the dedicated machine. This will happen soon after you start using the Varnish platform, as it will require some time to cache the pages that people browse. You can get the most out of the platform’s potential if the Internet sites that are using it also use a dedicated IP, but due to the fact that your server comes with a few IP addresses by default, you will not have to pay anything on top of the monthly charge for the machine itself.
