Varnish
Learn precisely what Varnish is. Discover much more about web accelerators and their function.
Varnish is a data caching platform, which is occasionally referred to as a caching HTTP reverse proxy. It’s a website accelerator that can boost the load speed of a website by up to 1000%, depending on the content itself. Every time a visitor opens any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor accesses it again. In this way, the web browser request from the visitor is not handled by the server and the web page will open substantially faster, since the Varnish caching platform can serve data many times faster than any server software. The end result will be a substantially faster loading website, which leads to an enormously improved visitor experience. When any of the cached pages is updated on the actual Internet site, the content that Varnish keeps in its memory is updated too, so the visitors will never end up seeing old content.

Varnish in Cloud Hosting
You can unleash Varnish’s potential and accelerate your sites regardless of the
cloud hosting plan that you have selected and you can enable and set up the content caching platform with several clicks through the easy-to-use GUI offered by our next-generation Hepsia hosting Control Panel. During the procedure, you’ll be able to select two different things – how many sites will use the Varnish caching platform, in other words – the number of instances, and how much data will be cached, i.e. the amount of memory. The latter comes in increments of 32 megabytes and is not bound to the number of instances, so you can order more instances and less memory and vice versa. If you have plenty of content on a particular Internet site and you gain plenty of website visitors, more memory will give you better results. You may also consider employing a dedicated IP address for the sites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with easy one-click controls for switching off or restarting any instance, for erasing the cache associated with any Internet site and for viewing exhaustive system logs.

Varnish in Semi-dedicated Servers
Varnish is a feature, which is included by default with all
semi-dedicated hosting plans that we are offering and you can use it for workload distribution purposes. It’s available in your Hepsia hosting Control Panel. The content caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any site that you host in the semi-dedicated server account. In case you’re in need of more, you can increase the memory quota. The memory itself is available in increments of 32 MB through the Control Panel’s Upgrades section. The exact same section will permit you to activate more instances too, if you’d like to use Varnish with more sites. The two upgrades can be added independently – you can cache the content of a single regularly visited site or run a number of Internet sites with the default memory quota. You can take full advantage of Varnish in case you use a dedicated IP and you can get one with your semi-dedicated package as well. Hepsia will grant you total control over the caching platform and, with no more than one mouse click, you will be able to clear the cache, to view a system log file or to reboot an instance.

Varnish in VPS Servers
You can use the load balancing capabilities of Varnish with any of our
Linux VPS plans if you choose Hepsia as your web hosting Control Panel. The content caching platform is available by default and the system memory that it will be able to use to cache the content of your websites depends on the specific package that you have selected, but even with the less powerful packages, you’ll have no less than several hundred MB of memory at your disposal only for content caching purposes. This amount is enough to optimize the performance of multiple Internet sites. It’ll take a little time for you to detect the effects, as Varnish caches the content that website visitors open, but shortly thereafter you will notice the significantly less load on your server and the accelerated Internet site load speed. The Varnish caching platform will permit you to use a lower-end plan for websites which would usually require a more costly hosting service.

Varnish in Dedicated Servers
All
Linux dedicated web hosting plans which are ordered with the tailor-made Hepsia website hosting Control Panel include Varnish, which is one of the pre-installed platforms that you will get with the dedicated server. The Varnish content caching platform can be set up and managed with ease from Hepsia’s time and effort saving graphical interface and, with no more than one mouse click, you can see an exhaustive log, add or reboot an instance, clear the cache for any site and much, much more. Soon after you activate the Varnish platform for a specific domain or sub-domain, it will begin caching the webpages requested by the site visitors and as soon as it has cached enough web content, you will perceive a tremendously better site performance and a reduced load. With Varnish-dedicated virtual memory starting at 3 gigabytes, you will be able to use the software platform for load balancing purposes even if you host plenty of websites on the machine.
