Varnish is a web accelerator platform, which caches content for the sake of faster access. It is sometimes referred to as an HTTP reverse proxy as well and it works between a web server and an Internet browser. When a site visitor accesses a particular page, the content is requested by the web browser, and then the web server handles this browser request and returns the needed content. If Varnish is activated for a particular site, it will cache its pages on the first visit and if the user visits a cached page for a second time, the information will be delivered by the accelerator platform instead of the web server. The boosted loading speed is an end result of the significantly faster response time that the Varnish platform offers as compared to any web server software. Of course, this does not mean that the visitors will continue being served the very same content again and again, as any update on any of the web pages is reflected in the content that the Varnish platform keeps in its memory.

Varnish in Shared Hosting

In case you host your Internet sites in a shared hosting account with us, you will be able to add Varnish with a few mouse clicks via your Control Panel. The platform is offered as an optional upgrade with all our hosting plans and you can choose the number of the websites that will use it and the total amount of system memory that will be available 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 aren’t tied directly to each other, so you can choose whether you want lots of memory for one single large-sized website or less memory for multiple smaller ones. You can take advantage of the full potential of the Varnish caching platform in case the websites use a dedicated IP. Using the hosting Control Panel, you can swiftly start/reboot/disable an instance, delete the cached files independently for each site that employs the Varnish platform or check an exhaustive log file.

Varnish in Semi-dedicated Hosting

The Varnish caching platform is part of the basic service set that you’ll receive in case you decide to host your Internet sites in a semi-dedicated server account. You can enable it for any of your Internet sites through our next-generation Hepsia hosting Control Panel. The default memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform at the same time. As these two things aren’t bound to each other, you can use a couple of sites with the default memory or you can get more memory in increments of 32 MB and use all of it for one single website. The Varnish caching platform works best if you assign a dedicated IP address to the websites that utilize its power. Hepsia will offer you an easy means of restarting any instance. Also, you’ll be able to delete the cached files with only one mouse click.

Varnish in VPS Hosting

You can take advantage of Varnish with each of our virtual private server packages at no additional cost, as the platform is pre-installed and is available by default. The one and 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 websites with just a couple of clicks. Each Virtual Private Server package comes with a different amount of system memory for data caching purposes, but you’ll have minimum several hundred MB, which is sufficient enough even for several traffic-heavy sites. Soon after you activate the Varnish platform, it’ll start caching the content that your visitors browse, so you will notice the much better page load speeds and the decreased load on the VPS server very soon. Varnish will allow you to use a less costly VPS server, since you will not need that much power to guarantee the proper operation of your Internet sites even if you own larger Internet sites with numerous visitors. Optimum results are achieved if the websites which use the Varnish platform use also a dedicated IP.

Varnish in Dedicated Web Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish platform at no additional cost and you will have total control over it through a very time and effort saving graphical interface – you’ll be able to start, to disable or to reboot an instance, to check an in-depth system log, to delete the cached content for any website and much, much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you host busy Internet sites with multiple visitors, you will notice the significantly faster page load times and the decreased load on the dedicated machine. This will become a fact soon after you start using the Varnish platform, since it will need some time to cache the content that users browse. You can get the most out of the platform’s capacity if the sites that are using it use also a dedicated IP address, but considering the fact that your dedicated server comes with several IPs by default, you will not have to pay anything on top of the monthly charge for the machine itself.
