Varnish is a web accelerator platform, which caches data for faster access. It’s sometimes referred to as an HTTP reverse proxy as well and it interacts between a web server and a web browser. When a website visitor opens a particular page, the content is requested by the browser, and then the web server handles this request and delivers the needed information. If Varnish is enabled for a certain site, it will cache the pages at the very first request and in case the visitor visits a cached page once more, the data will be delivered by the caching platform and not by the web server. The improved loading speed is a result of the considerably faster response speed that the Varnish platform offers as compared to any server software. Of course, this doesn’t mean that the users will continue seeing the exact same content over and over again, as any change on any of the pages is reflected in the content that Varnish caches in its memory.
Varnish in Website Hosting
You can take advantage of Varnish’s full potential and enhance the speed of your websites irrespective of the website hosting plan that you have chosen and you can activate and configure the platform with a couple of mouse clicks from the user-friendly interface offered by our next-gen Hepsia hosting Control Panel. During the procedure, you’ll be able to select two different things – how many Internet sites will employ Varnish, in other words – the number of instances, and how much content will be cached, in other words – the amount of memory. The latter is offered in increments of 32 MB and is not linked to the number of instances, so you can add more instances with less memory and vice versa. If you’ve got a lot of content on a particular website and you win a lot of site visitors, more system memory will give you better results. You may also consider employing a dedicated IP for the websites that will use the Varnish caching platform. Hepsia will offer you easy one-click controls for switching off or rebooting any instance, for erasing the cache for each Internet site and for seeing in-depth logs.
Varnish in Dedicated Servers Hosting
If you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish content caching platform at no extra charge and you’ll have full control over it through an incredibly simple-to-navigate graphical interface – you’ll be able to start, to stop or to reboot an instance, to browse an elaborate log, to delete the cached data for any website and much more. Varnish will have several gigabytes of memory at its disposal, so even if you have traffic-hungry websites with lots of visitors, you’ll notice the tremendously better site load speeds and the decreased load on the server. This will become a fact soon after you start using Varnish, since it will need some time to cache the content that people open. You can make the most of the platform’s capabilities if the Internet sites that are using it also use a dedicated IP, but since your server includes a few IP addresses by default, you will not have to pay anything on top of your monthly charge for the server itself.
