Varnish is a web app accelerator platform, which caches data for the sake of faster response times. It’s sometimes referred to as a caching HTTP reverse proxy too and it works between a web server and its users. When a visitor accesses a particular web page, its content is requested by the Internet browser, and then the web server processes this browser request and sends back the necessary information. If Varnish is activated for a particular site, it will cache the pages on the first request and if the visitor visits a cached page once again, the data will be delivered by the accelerator platform and not by the web server. The improved load speed is an end result of the much faster response speed that the Varnish platform offers as compared to any server software. Of course, this does not mean that the visitors will continue seeing the very same content over and over again, as any modification on any of the web pages is reflected in the content that Varnish keeps in its memory.

Varnish in Hosting

You can unlock Varnish’s full potential and accelerate your websites’ loading speed irrespective of the hosting package that you’ve chosen and you can activate and set up the data caching platform with a few clicks from the intuitive graphical interface offered by our innovative Hepsia Control Panel. During the process, you’ll be able to choose two different things – how many websites will use the Varnish platform, i.e. the number of instances, and how much information will be cached, in other words – the amount of memory. The latter is available in increments of 32 MB and is not tied to the number of instances, so you can use more instances and less memory and vice versa. If you’ve got lots of content on a particular site and you receive a lot of website visitors, more memory will guarantee you better results. You may also consider employing a dedicated IP for the sites that will use the Varnish caching platform. Hepsia will provide you with easy one-click buttons for cancelling or rebooting any instance, for clearing the cache for any site and for checking comprehensive logs.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is included in the standard service set that you’ll acquire in case you choose to host your websites in a semi-dedicated server account. You can set it up for any of your sites through our cutting-edge Hepsia Control Panel. The default system memory that Varnish can use to cache content is 64 megabytes, but if you decide that you want more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform at the same time. Since these two things are not tied to each other, you can use a few websites with the default memory or you can add more memory in increments of 32 megabytes and use all of it for one single Internet site. The Varnish caching platform works best when you assign a dedicated IP to the Internet sites that utilize its power. Hepsia will give you an easy means of rebooting any instance. What’s more, you’ll be able to clear the cached data with just one click of the mouse.

Varnish in VPS Servers

You can use the load balancing capabilities of Varnish with all our VPS servers if you pick Hepsia as your hosting Control Panel. The Varnish platform is offered by default and the amount of memory that it will be able to use to cache your website content depends on the particular package that you’ve selected, but even with the less powerful plans, you will have at least several hundred megabytes of memory at your disposal only for caching purposes. This amount is sufficient enough to improve the work of numerous sites. It’ll take some time for you to notice the effects, as the Varnish platform caches the content that site visitors open, but shortly thereafter you’ll notice the significantly reduced server load and the improved site loading speed. The Varnish platform will permit you to make use of a lower-end VPS package for websites that would typically need a more expensive web hosting solution.

Varnish in Dedicated Servers

All dedicated servers which are ordered with the in-house developed Hepsia website hosting Control Panel come with Varnish, which is among the pre-installed platforms that you will get with the dedicated machine. The Varnish content caching platform can be set up and administered with no effort from Hepsia’s user-friendly GUI and, with no more than a click, you can see a comprehensive system log, create or restart an instance, delete the cached content for any site and much, much more. Shortly after you configure the Varnish platform for a certain domain or subdomain, it will start caching the pages accessed by the site visitors and as soon as it has cached enough web content, you’ll perceive a tremendously faster site performance and a lowered load on your dedicated machine. With Varnish-dedicated virtual memory starting at 3 gigabytes, you’ll be able to use the software platform for load balancing purposes even if you run numerous Internet sites on your machine.
