Varnish is a website accelerator, which has been gaining a lot of popularity lately, because it can increase the loading speed of any website, at times even by 100 percent, depending on the content itself. This tool is sometimes referred to as an HTTP reverse proxy as well and is used to reduce the overall server load and to boost the browsing speed for the website visitors. Every time a visitor opens a page on a particular site, the browser request is handled by the web server and the requested information is sent as a response. If the Varnish accelerator is activated, it caches the web pages that the website visitor opens and if any of them is loaded once more, it’s served by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator handles the browser requests considerably faster than any web server, which leads to much faster browsing speeds for the visitors. If any data is edited meanwhile, the cached pages will also be updated the next time somebody tries to open them.
Varnish in Cloud Hosting
You can use Varnish’s full potential and improve your websites’ speed regardless of the cloud hosting package that you’ve selected and you can enable and configure the data caching platform with several mouse clicks through the intuitive graphical interface offered by our innovative Hepsia Control Panel. During the procedure, you will be able to choose two different things – how many websites will employ Varnish, i.e. the number of instances, and how much data will be cached, i.e. the amount of memory. The latter comes in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances and less memory and vice versa. In case you have plenty of content on a certain site and you get numerous visitors, more memory will give you a better result. You may also consider using a dedicated IP address for the websites that will use the Varnish platform. Hepsia will provide you with easy 1-click controls for turning off or rebooting any instance, for erasing the cache for each site and for checking exhaustive logs.
Varnish in VPS Servers
We offer Varnish with all of the Hepsia-managed VPS hosting plans, so in case you order a server with this Control Panel, you’ll be able to take advantage of the data caching platform at no extra fee. Varnish can utilize different amounts of system memory for data caching purposes based on the very plan that you have chosen during the registration process, but at any rate, this amount won’t be less than several hundred megabytes. This is quite enough to optimize the work of a handful of heavy Internet sites, so the faster site loading speeds and the reduced load on the VPS server will be noticeable. The effect may not be obvious immediately, as the Varnish platform will need a certain amount of time to cache the website content that users access, but shortly after you set it up, you will observe its full capacity. This caching platform will allow you to use a less powerful server and to give less cash to get the very same performance you’d get with a more powerful virtual machine without Varnish.
