Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the loading speed of any website, sometimes even by 100 percent, depending on the content itself. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to lower the overall load on the physical server and to accelerate the access speed for the website visitors. Each time a visitor loads a page on a particular Internet site, the web browser request is taken care of by the web server and the requested information is returned as a reply. If the Varnish accelerator is activated, it caches the pages that the website visitor opens and in case any of them is accessed once more, it’s fetched by Varnish and not by the server directly. The performance improvement is due to the fact that the accelerator processes the browser requests substantially faster than any web server, which leads to much faster browsing speeds for the visitors. In case any content is edited meanwhile, the cached pages will also be ‘refreshed’ the next time someone opens them.
Varnish in Cloud Website Hosting
In case you host your Internet sites in a cloud website hosting account with us, you will be able to activate Varnish with a few mouse clicks through your Control Panel. The platform comes as an upgrade with all our plans and you can choose the number of the sites that will use it and the maximum amount of system memory that will be used for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they are not directly tied to each other, so you can choose whether you want lots of memory for one large site or less memory for several smaller ones. You can take advantage of the full potential of the Varnish platform if the websites use a dedicated IP address. Using the Control Panel, you can swiftly start/reboot/terminate an instance, delete the cached files individually for each website which employs Varnish or view an elaborate log file.
Varnish in VPS Web Hosting
We offer Varnish with all of the Hepsia-equipped Linux VPS web hosting, so if you acquire a server with this Control Panel, you’ll be able to take full advantage of the caching platform at no additional fee. Varnish can utilize different amounts of memory for data caching purposes depending on the specific VPS plan that you have selected during the server order process, but in any case, this amount will not be less than several hundred megabytes. This is more than enough to boost the work of a number of resource-hungry sites, so the better website loading speeds and the decreased load on your VPS server will be noticeable. The result may not be evident straight away, since Varnish will need a certain amount of time to cache the website content that people browse, but soon after you activate it, you’ll witness its full capacity. This platform will allow you to use a lower-end server and to give less money to get the same performance you would get with a higher-end machine without Varnish.
