Varnish is a content caching platform, which is sometimes called a caching HTTP reverse proxy. It is a web accelerator that can increase the load speed of a site by up to 1000 percent, depending on the content itself. Every time a visitor opens any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor accesses it again. In this way, the browser request from the visitor is not handled by the server and the web page will load considerably faster, as the Varnish platform can serve content many times faster than any web server software. The end result will be a significantly faster loading website, which means an enormously improved visitor experience. When any of the cached pages is updated on the live site, the information that Varnish keeps in its memory is ‘refreshed’ too, so the site visitors will never see old data.
Varnish in Cloud Website Hosting
You can unlock Varnish’s potential and enhance the loading speed of your sites irrespective of the cloud website hosting package that you have picked and you can enable and set up the platform with a few clicks through the simple-to-work-with graphical interface offered by our avant-garde Hepsia Control Panel. During the procedure, you’ll be able to choose two separate things – how many sites will use Varnish, i.e. the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter is available in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances and less memory and the other way around. In case you’ve got plenty of content on a particular site and you win lots of site visitors, more system memory will give you better results. You may also consider employing a dedicated IP address for the sites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with simple one-click buttons for removing or rebooting any instance, for deleting the cache associated with each Internet site and for seeing elaborate system logs.
Varnish in VPS Servers
We offer Varnish with all Hepsia-managed VPS hosting plans, so in case you obtain a server with this Control Panel, you will be able to use the caching platform at no additional charge. Varnish can utilize different amounts of system memory for content caching purposes based on the very server configuration that you have picked during the server order process, but in any case, this amount won’t be less than several hundred MB. This is more than enough to enhance the overall performance of a handful of busy sites, so the faster web page browsing speeds and the decreased load on your virtual server will be perceivable. The result may not be observable instantly, since the Varnish platform will require some time to cache the site content that users request, but soon after you set it up, you’ll perceive its full capacity. This caching platform will allow you to use a lower-end VPS and to give less cash to get the same performance you’d get with a higher-end virtual machine without Varnish.
