Varnish is a website accelerator tool, which has been gaining a lot of popularity lately, because it can increase the loading speed of any site, at times even by 100%, depending on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to decrease the overall load on the server and to boost the access speed for the site visitors. Whenever a visitor accesses a page on a given Internet site, the web browser request is taken care of by the web server and the requested content is served as a response. If Varnish is activated, it caches the pages that the site visitor opens and if any of them is loaded once more, it is fetched by Varnish and not by the web server directly. The boost in the overall performance comes from the fact that the accelerator processes the browser requests significantly faster than any web server, which leads to much faster browsing speeds for the website visitors. In case any data is modified meanwhile, the cached web pages will also be ‘refreshed’ the next time someone tries to access them.

Varnish in Cloud Hosting

If you host your sites under a cloud hosting account with us, you will be able to activate Varnish with a couple of clicks of the mouse via your Control Panel. The platform is available as an optional upgrade with all our shared packages and you can choose the number of the websites that will use it and the total amount of system memory that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they are not tied directly to each other, so you can choose if you need plenty of memory for one single large website or less memory for multiple smaller ones. You can make use of the full potential of the Varnish platform if the sites use a dedicated IP address. Using the hosting Control Panel, you can effortlessly start/restart/discontinue an instance, clear the cached content independently for each site which employs Varnish or view a detailed system log.

Varnish in Semi-dedicated Hosting

The Varnish caching platform is part of the basic service set that you will obtain when you choose to host your sites in a semi-dedicated server account. You can activate 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 megabytes, but in case you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. Since these two things are not bound to each other, you can use a few websites with the default memory or you can add more memory in increments of 32 MB and use all of it for a single Internet site. Varnish works best if you use a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will offer you a simple means of restarting any instance. On top of that, you will be able to clear the cached files with just one single click of the mouse.

Varnish in VPS Web Hosting

We provide Varnish with all Hepsia-managed Linux VPS web hosting services, so if you purchase a server with this Control Panel, you will be able to use the caching platform at no extra charge. The Varnish platform can use different amounts of memory for data caching purposes depending on the very Virtual Private Server plan that you’ve selected during the server order process, but in any case, this amount will not be less than several hundred megabytes. This is quite enough to optimize the performance of a number of resource-hungry Internet sites, so the better site loading speeds and the reduced load on your Virtual Private Server will be perceptible. The effect may not be detectable straight away, as Varnish will require a certain amount of time to cache the website content that users request, but soon after you enable it, you will feel its full capacity. This caching platform will permit you to use a less powerful server and to pay less money to get the same performance you would get with a higher-end machine without Varnish.

Varnish in Dedicated Servers Hosting

If you order a dedicated server with the Hepsia hosting Control Panel, you will acquire Varnish at no additional fee and you’ll exert full control over it through a really intuitive graphical interface – you’ll be able to start, to terminate or to restart an instance, to view a detailed log, to delete the cached content associated with any website and much, much more. Varnish will have several GB of memory at its disposal, so even if you have traffic-intensive Internet sites with plenty of visitors, you’ll notice the significantly faster page loading speeds and the less load on the dedicated server. This will become a fact soon after you start using Varnish, since it will need a certain amount of time to cache the web pages that users browse. You can get the most out of the platform’s potential if the sites that are using it also use a dedicated IP, but due to the fact that your server includes a few IPs by default, you won’t have to pay anything on top of your monthly charge for the machine itself.
