Varnish is a web application accelerator platform, which caches info for faster access. It is occasionally called a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a website visitor accesses a given webpage, its content is requested by the browser, and then the web server handles this request and delivers the needed information. If Varnish is enabled for a specific site, it will cache the pages at the very first request and in case the user opens a cached page once again, the content will be delivered by the caching platform and not by the web server. The increased load speed is a result of the significantly faster response time that the Varnish platform offers compared to any web server software. Of course, this doesn’t mean that the users will continue being served the same content again and again, since any update on any of the pages is reflected in the content that Varnish saves in its memory.

Varnish in Shared Website Hosting

If you host your websites in a shared website hosting account with us, you will be able to activate Varnish with a few clicks through your Control Panel. The platform is offered as an upgrade with all our web hosting packages and you can choose the number of the websites that will use it and the maximum amount of system memory that will be used for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they are not tied directly to each other, so you can choose whether you want plenty of memory for a single large-scale website or less memory for multiple smaller ones. You can make use of the full potential of the Varnish caching platform if the sites use a dedicated IP. Using the hosting Control Panel, you can effortlessly start/reboot/discontinue an instance, clear the cached data individually for each site which employs Varnish or see an exhaustive system log.

Varnish in Semi-dedicated Servers

Varnish is a feature, which is included by default with all semi-dedicated servers that we offer and you can use it for workload distribution purposes. It’s available in your Hepsia hosting Control Panel. The caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can use it with any website that you host in your semi-dedicated server account. If you need more, you can increase the memory allocation. 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 as well, in case you’d like to use Varnish with more sites. The two upgrades can be ordered independently – you can cache the content of a single traffic-heavy website or use a number of websites with the default memory. You can get the most out of Varnish if you’ve got a dedicated IP and you can order one with your semi-dedicated server plan as well. Hepsia will grant you total control over the platform and, with no more than one click of the mouse, you’ll be able to clear the cached content, to see a log or to reboot an instance.

Varnish in VPS Servers

You can take advantage of Varnish with all our VPS server plans at no extra charge, since the caching platform is pre-installed and is included by default. The only prerequisite is that the Virtual Private Server must be ordered with the Hepsia Control Panel, through which you’ll be able to set up Varnish for any of your sites with only a couple of clicks. Each plan features a different amount of memory for data caching purposes, but you will get minimum several hundred megabytes, which is sufficient enough even for multiple large-size sites. Soon after you set up Varnish, it will start caching the content that your site visitors request, so you will notice the significantly faster page load speeds and the lowered load very soon. The caching platform will allow you to use a less pricey virtual machine, since you will not require that much power to ensure the proper operation of your Internet sites even if you have traffic-hungry Internet sites with numerous visitors. Best results are achieved if the websites that use the Varnish platform also use a dedicated IP address.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you will get the Varnish caching platform at no extra fee and you’ll exert full control over it via a truly easy-to-work-with graphical interface – you will be able to start, to delete or to restart an instance, to view an elaborate log, to delete the cached data associated with any website and much, much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you’ve got large-scale sites with a vast number of visitors, you will notice the much faster site loading times and the less load on the dedicated server. This will become a fact shortly after you begin using the Varnish platform, since it will require a certain amount of time to cache the content that users browse. You can take full advantage of the platform’s capability if the 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 fee for the server itself.
