Varnish is a web application accelerator platform, which caches content for faster access. It’s occasionally called an HTTP reverse proxy as well and it interacts between a web server and a browser. When a site visitor opens a particular web page, its content is requested by the browser, and then the web server processes this request and sends back the required data. If Varnish is enabled for a certain site, it will cache its pages at the very first request and in case the visitor opens a cached page for a second time, the data will be delivered by the caching platform and not by the web server. The boosted load speed is an end result of the much faster response speed that Varnish offers as compared to any web server software. Of course, this does not mean that the visitors will keep being served the exact same content again and again, as any update on any of the pages is reflected in the content that the Varnish platform keeps in its system memory.
Varnish in Shared Hosting
You can take advantage of Varnish’s potential and boost the speed of your sites irrespective of the shared hosting plan that you’ve selected and you can add and configure the content caching platform with a few clicks of the mouse through the user-friendly GUI offered by our next-generation Hepsia hosting Control Panel. During the process, you’ll be able to choose two different things – how many websites will employ the Varnish platform, i.e. the number of instances, and how much data will be cached, in other words – the amount of memory. The latter comes in increments of 32 megabytes and is not linked to the number of instances, so you can add more instances with less memory and the other way around. If you’ve got a lot of content on a given site and you get plenty of visitors, more memory will give you better results. You may also consider using a dedicated IP for the sites that will use the Varnish platform. Hepsia will offer you easy 1-click controls for stopping or rebooting any instance, for erasing the cache for each site and for viewing in-depth system logs.
Varnish in Semi-dedicated Servers
The Varnish content caching platform is an essential part of the basic service set that you will obtain if you decide to host your websites under a semi-dedicated server account. You can activate it for any of your websites through our next-generation Hepsia hosting Control Panel. The default amount of memory that the Varnish platform can use to cache content is 64 MB, but in case you decide that you want more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this platform simultaneously. As these two features are not tied to each other, you can use a couple of Internet sites with the default memory or you can get more memory in increments of 32 MB and use all of it for one single website. The Varnish platform works best when you set a dedicated IP address for the Internet sites that utilize its power. The Hepsia Control Panel will offer you an easy way of restarting any instance. What’s more, you will be able to delete the cached content with just one single click of the mouse.
Varnish in VPS Servers
You can take full advantage of the workload balancing potential of Varnish with each of our VPS servers if you select Hepsia as your Control Panel. The Varnish content caching platform is offered by default and the memory that it’ll be able to use to cache the content of your websites depends upon the specific VPS package that you have selected, but even with the lower-end packages, you will have no less than several hundred megabytes of system memory at your disposal only for content caching purposes. This amount is sufficient to boost the work of numerous websites. It will take some time for you to observe the results, since the Varnish platform caches the content that website visitors request, but shortly after that you’ll notice the considerably lowered load on the VPS server and the improved site loading speed. The Varnish caching platform will permit you to use a less powerful Virtual Private Server package for Internet sites that would usually require a more costly hosting service.
Varnish in Dedicated Servers
When you want a powerful website hosting solution and you acquire any of the dedicated servers offered by us, you can use the Varnish data caching platform to optimize the overall performance of your Internet sites at no extra fee as long as the server is ordered with our avant-garde Hepsia Control Panel. Its easy-to-navigate graphical interface will allow you to keep an eye on platform processes, to clear the cached contents or to reboot any instance with one single click. The smallest amount of memory that the Varnish caching platform can use to cache Internet site content is three gigabytes, which is more than enough for a large collection of large-size sites, so your server will be able to cope with a substantial system load while your visitors are enjoying a smooth web browsing experience. As your dedicated server will include a number of dedicated IP addresses, you’ll be able to make use of Varnish’s maximum potential.
