Varnish is a web accelerator platform, which caches information for the sake of faster response times. It’s occasionally referred to as a caching HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a website visitor loads a given web page, its content is requested by the web browser, and then the web server processes this browser request and delivers the required data. If Varnish is activated for a particular site, it will cache the pages at the first request and if the visitor visits a cached page again, the data will be delivered by the accelerator platform and not by the server. The increased load speed is a result of the substantially faster response speed that Varnish offers as compared with any server software. Of course, this does not mean that the users will continue being served the exact same content over and over again, since any update on any of the pages is reflected in the content that Varnish caches in its system memory.
Varnish in Hosting
You can unleash Varnish’s full potential and enhance your sites’ load speed irrespective of the hosting plan that you’ve chosen and you can enable and configure the content caching platform with a few clicks from the easy-to-work-with interface offered by our cutting-edge Hepsia hosting Control Panel. During the process, you’ll be able to select two different things – how many websites will use the Varnish platform, in other words – the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter comes in increments of 32 MB and is not bound to the number of instances, so you can order more instances with less memory and vice versa. If you have lots of content on a certain Internet site and you draw a lot of visitors, more memory will give you a better result. You may also consider using a dedicated IP address for the sites that will use the Varnish platform. Hepsia will provide you with simple 1-click buttons for deleting or rebooting any instance, for erasing the cache for any site and for viewing comprehensive logs.
Varnish in VPS Servers
You can take full advantage of the load balancing potential of Varnish with all our VPS servers in case you choose Hepsia as your hosting Control Panel. The content caching platform is available by default and the amount of memory that it’ll be able to use to cache your website content depends upon the given plan that you’ve picked, but even with the lower-end plans, you’ll have at least several hundred megabytes of system memory at your disposal solely for caching purposes. This amount is enough to optimize the performance of numerous sites. It’ll take some time for you to notice the effects, since Varnish caches the content that site visitors access, but shortly after that you will notice the considerably lowered load on your Virtual Private Server and the improved site load speed. The Varnish caching platform will permit you to use a lower-end Virtual Private Server package for sites that would typically need a more expensive web hosting solution.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you will get Varnish at no extra cost and you will have complete control over it through an extremely user-friendly interface – you will be able to start, to cancel or to restart an instance, to browse an in-depth system log, to clear the cached data associated with any Internet site and much, much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you manage resource-requiring websites with a huge number of visitors, you’ll notice the substantially faster website load times and the less load. This will happen shortly after you begin using the Varnish platform, as it will need some time to cache the site content that users request. You can make the most of the platform’s potential if the Internet sites that are using it also use a dedicated IP, but since your dedicated server includes a couple of IP addresses by default, you will not have to pay anything on top of the monthly fee for the machine itself.
