Varnish is a web application accelerator platform, which caches content for the sake of faster access. It is occasionally called a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a site visitor accesses a certain webpage, the content is requested by the browser, and then the web server handles this request and returns the requested information. If Varnish is activated for a particular site, it will cache the pages at the first visit and if the visitor visits a cached page for a second time, the info will be delivered by the accelerator platform and not by the web server. The accelerated loading speed is a result of the considerably faster response time that the Varnish platform offers compared to any server software. At the same time, this does not mean that the visitors will continue being served the same content again and again, because any update on any of the pages is reflected in the content that the Varnish platform saves in its system memory.
Varnish in Cloud Hosting
Varnish comes as an optional upgrade with each and every cloud hosting plan and if you’d like to use it, you can add it to your shared web hosting account using the Upgrades menu in your Hepsia hosting Control Panel. There are two separate features that can be upgraded – the instances and the system memory. The first one refers to the number of the Internet sites that you would like to employ Varnish for, whereas the second, which is offered in increments of 32 MB, indicates the total amount of content that the content caching platform can store at any particular time. The Hepsia Control Panel’s intuitive graphical interface will enable you to terminate or to reboot any instance, to see detailed system logs or to erase the platform’s cache with just one click. For maximum results, you can employ a dedicated IP address for the websites that will use the platform. With Varnish, your site will load considerably faster, meaning more happy website users and potential customers.
Varnish in Dedicated Servers
If you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish content caching platform at no additional fee and you will have complete control over it via a rather intuitive GUI – you will be able to start, to delete or to reboot an instance, to check a comprehensive system log, to delete the cached data for any website and much more. Varnish will have several GB of memory at its disposal, so even if you’ve got busy websites with many visitors, you will notice the substantially faster website loading times and the decreased load on your server. This will happen soon after you start using the Varnish platform, as it will need some time to cache the site content that users access. You can take full advantage of the platform’s capacity if the Internet sites that are using it also use a dedicated IP address, but owing to the fact that your dedicated server comes with a few IPs by default, you won’t need to pay anything on top of the monthly charge for the machine itself.
