Varnish is a web application accelerator platform, which caches information for the sake of faster access. It is sometimes called a caching HTTP reverse proxy too and it interacts between a web server and an Internet browser. When a visitor opens a given webpage, its content is requested by the web browser, and then the server handles this browser request and returns the needed info. If Varnish is enabled for a particular site, it will cache its pages at the first visit and in case the visitor accesses a cached page once more, the information will be delivered by the accelerator platform and not by the server. The boosted load speed is an end result of the considerably faster response time that the Varnish platform offers compared to any web server software. Of course, this does not mean that the users will keep being served the same content again and again, as any update on any of the pages is reflected in the content that the Varnish platform stores in its system memory.

Varnish in Shared Web Hosting

In case you host your websites under a shared web hosting account with us, you’ll be able to activate Varnish with a couple of mouse clicks through your hosting Control Panel. The platform is offered as an upgrade with all our shared packages and you can choose how many websites will use it and the total storage space that will be available for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t tied directly to each other, so you can decide whether you want plenty of memory for one large-size site or less memory for several smaller ones. You can unlock the full potential of the Varnish caching platform in case the websites use a dedicated IP. With the hosting Control Panel, you can swiftly start/reboot/discontinue an instance, delete the cached data individually for each site that uses Varnish or see an elaborate log.

Varnish in Semi-dedicated Hosting

The Varnish data caching platform is part of the standard service set that you will receive in case you decide to host your sites in a semi-dedicated server account. You can enable it for any of your Internet sites via our next-gen Hepsia hosting Control Panel. The default amount of memory that the Varnish caching platform can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this amount of memory 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 features are not tied to each other, you can use several Internet sites with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for a single web site. The Varnish caching platform works best if you allocate a dedicated IP to the websites that utilize its power. The Hepsia Control Panel will provide you with an easy means of restarting any instance. Furthermore, you’ll be able to clear the cached data with just one single click.

Varnish in VPS Hosting

You can take advantage of Varnish with all our virtual private server plans at no additional fee, as the data caching platform is pre-installed and is offered by default. The one and only condition is that the Virtual Private Server must be ordered with the Hepsia hosting Control Panel, via which you’ll be able to set up Varnish for any of your sites with only a few clicks of the mouse. Each plan features a different amount of memory for caching purposes, but you will have at least several hundred MB, which is quite sufficient even for several resource-heavy Internet sites. Soon after you enable Varnish, it’ll start caching the content that your site visitors browse, so you will notice the tremendously better webpage load speeds and the decreased load in no time. The Varnish caching platform will permit you to use a less costly virtual server, as you will not need that much power to ensure the uninterrupted operation of your Internet sites even if you manage high-demand Internet sites with numerous visitors. Best results are accomplished if the Internet sites that use the Varnish caching platform also use a dedicated IP address.

Varnish in Dedicated Web Hosting

If you order a dedicated server with the Hepsia Control Panel, you’ll get the Varnish platform at no additional fee and you’ll have full control over it via a truly user-friendly interface – you will be able to start, to disable or to restart an instance, to view an elaborate log, to delete the cache associated with any website and much, much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you manage resource-hungry Internet sites with a huge number of visitors, you will notice the much faster website loading times and the decreased load on your server. This will happen soon after you start using Varnish, since it will need some time to cache the content that users browse. You can take full advantage of the platform’s capabilities in case the Internet sites that are using it use also a dedicated IP, but owing to the fact that your server includes several IP addresses by default, you won’t have to pay anything on top of your monthly charge for the machine itself.
