Varnish is a data caching platform, which is occasionally referred to as a caching HTTP reverse proxy. It is a web accelerator tool that can accelerate the load speed of a site by up to one thousand percent, based on its content. Whenever a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor loads it again. Thus, the browser request from the visitor is not processed by the server and the web page will open tremendously faster, as the Varnish caching platform can serve content many times faster than any web server software. The end result is a considerably faster loading page, which leads to an enormously improved browsing experience. In case any of the cached webpages is updated on the actual Internet site, the information that Varnish caches in its system memory is ‘refreshed’ too, so the website visitors won’t see old information.

Varnish in Hosting

You can unlock Varnish’s full potential and improve your websites’ speed regardless of the hosting plan that you’ve selected and you can add and set up the content caching platform with several mouse clicks using the simple-to-work-with interface offered by our advanced Hepsia hosting Control Panel. During the procedure, you will be able to select two separate things – how many sites will employ the Varnish caching platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of system memory. The latter comes in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances with less memory and the other way around. In case you’ve got plenty of content on a given Internet site and you get lots of visitors, more system memory will give you a better result. You may also consider employing a dedicated IP for the sites that will use the Varnish platform. The Hepsia Control Panel will offer you simple 1-click buttons for disabling or restarting any instance, for clearing the cache associated with each site and for seeing exhaustive system logs.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is included in the basic service set that you will receive if you decide to host your Internet sites in a semi-dedicated server account. You can configure it for any of your sites through our next-generation Hepsia hosting Control Panel. The default amount of system memory that Varnish can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this caching platform at the same time. Since these two features are not tied to each other, you can use a few websites with the default amount of memory or you can order more memory in increments of 32 MB and use all of it for a single site. The Varnish platform performs best if you set a dedicated IP for the websites that utilize its power. Hepsia will give you a simple way of rebooting any instance. What’s more, you’ll be able to clear the cached contents with just one single mouse click.

Varnish in VPS Hosting

You can use the load balancing potential of Varnish with any of our VPS hosting in case you choose Hepsia as your Control Panel. The data caching platform comes by default and the amount of system memory that it will be able to use to cache your website content depends on the specific package that you have chosen, but even with the less powerful packages, you’ll have no less than several hundred megabytes of system memory at your disposal solely for caching purposes. This amount is enough to improve the overall performance of numerous sites. It’ll take a little time for you to observe the results, as the Varnish platform caches the content that website visitors browse, but shortly thereafter you will notice the significantly lowered load on the machine and the enhanced site browsing speed. Varnish will permit you to use a less powerful package for Internet sites which would usually require a more high-priced hosting service.

Varnish in Dedicated Web Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you will get the Varnish content caching platform at no extra fee and you will exert full control over it via an amazingly easy-to-work-with graphical interface – you will be able to start, to disable or to reboot an instance, to check a detailed log, to clear the cached files associated with any site and much more. Varnish will have several GB of virtual memory at its disposal, so even if you manage resource-heavy sites with many visitors, you’ll notice the significantly better page loading speeds and the less load on the machine. This will happen soon after you begin using Varnish, as it will need a certain amount of time to cache the content that users open. You can get the most out of the platform’s capacity if the websites that are using it use also a dedicated IP address, but due to the fact that your dedicated server includes a few IPs by default, you won’t need to pay anything on top of the monthly charge for the server itself.
