Varnish is a web accelerator platform, which caches information for the sake of faster response times. It is occasionally referred to as an HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a website visitor accesses a certain webpage, its content is requested by the Internet browser, and then the web server processes this browser request and delivers the needed info. If Varnish is enabled for a given website, it will cache its pages at the first request and in case the visitor opens a cached page for a second time, the info will be delivered by the accelerator platform and not by the server. The increased loading speed is a result of the significantly faster response speed that the Varnish platform offers compared to any web server software. Of course, this does not mean that the users will continue seeing the same content again and again, as any change on any of the pages is reflected in the content that Varnish keeps in its memory.

Varnish in Cloud Web Hosting

You can unleash Varnish’s potential and accelerate your sites’ speed irrespective of the cloud web hosting plan that you have selected and you can enable and configure the content caching platform with a couple of clicks through the intuitive GUI offered by our next-generation Hepsia hosting Control Panel. In the meantime, you will be able to select two different things – how many websites will use the Varnish caching platform, in other words – the number of instances, and how much content will be cached, in other words – the amount of memory. The latter is offered in increments of 32 MB and is not linked to the number of instances, so you can add more instances and less memory and the other way around. If you’ve got plenty of content on a given website and you get numerous website visitors, more system memory will guarantee you better results. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish platform. The Hepsia Control Panel will provide you with easy one-click buttons for turning off or rebooting any instance, for clearing the cache associated with any Internet site and for viewing comprehensive system logs.

Varnish in Semi-dedicated Servers

Varnish is a feature, which is offered by default with all semi-dedicated servers that we are offering and you can use it for load balancing purposes. It’s available in your Hepsia Control Panel. The Varnish caching platform comes with 64 MB of system memory for cached data storing purposes and you can employ it with any website that you host in your account. In case you need more, you can increase the system memory allocation. The memory itself is offered in increments of 32 megabytes through the Control Panel’s Upgrades section. The same Upgrades section will enable you to create more instances too, if you wish to use the Varnish platform with more websites. The two upgrades can be ordered independently – you can cache the content of a single traffic-heavy site or use several different sites with the default memory. You can take full advantage of the Varnish caching platform if you have a dedicated IP address and you can order one with your semi-dedicated server plan as well. The Hepsia Control Panel will give you total control over the caching platform and, with no more than one single click, you’ll be able to clear the cached content, to check a log file or to reboot an instance.

Varnish in Dedicated Servers

All dedicated servers that are ordered with the in-house developed Hepsia website hosting Control Panel feature Varnish, which is one of the pre-installed software platforms that you will get with the machine. The Varnish caching platform can be set up and administered with ease through Hepsia’s easy-to-navigate interface and, with no more than one mouse click, you can browse an in-depth log, create or reboot an instance, delete the cache for any website and much more. Shortly after you activate Varnish for a given domain or sub-domain, it will start caching the pages loaded by your site visitors and as soon as it has cached enough content, you will observe a considerably faster website performance as well as a lowered load. With Varnish-dedicated system memory starting at 3 gigabytes, you’ll be able to use the software platform for workload distribution purposes even if you host a huge number of websites on the dedicated machine.
