Varnish is a web accelerator platform, which caches information for faster response times. It is sometimes called an HTTP reverse proxy as well and it works between a web server and an Internet browser. When a site visitor accesses a given webpage, its content is requested by the browser, and then the server processes this request and returns the necessary content. If Varnish is activated for a site, it will cache the pages on the very first request and in case the visitor opens a cached page once more, the content will be delivered by the accelerator platform and not by the server. The increased loading speed is an end result of the considerably faster response time that the Varnish platform offers compared with any server software. Of course, this does not mean that the site visitors will continue being served the exact same content over and over again, because any change on any of the web pages is reflected in the content that the Varnish platform stores in its system memory.

Varnish in Shared Website Hosting

If you host your websites under a shared website hosting account with our company, you’ll be able to activate Varnish with a few mouse clicks via your hosting Control Panel. The platform comes as an optional upgrade with all our shared web hosting plans 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 content. The two upgradeable features 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 decide if you need a lot of memory for one large-sized website or less memory for multiple smaller ones. You can unlock the full potential of Varnish if the websites use a dedicated IP. Using the hosting Control Panel, you can effortlessly start/reboot/stop an instance, clear the cached contents individually for each website that uses Varnish or see an elaborate log file.

Varnish in Semi-dedicated Hosting

All our Linux semi-dedicated hosting packages include Varnish by default, so you can make full use of the accelerator and boost the speed of any site that you host on our platform. You’ll get 64 megabytes of memory particularly for Varnish at no extra cost and you can add an instance with no more than a few mouse clicks from the Hepsia hosting Control Panel, which comes with the semi-dedicated plans. If you need more memory, the latter is offered in increments of 32 megabytes through the Upgrades section of the Control Panel and it will be at your disposal instantaneously. You can also add more instances as an upgrade, so you can choose whether lots of data will be cached for one website or whether the memory will be utilized by several sites. Hepsia will permit you to restart or to stop any instance, to check the system log associated with it or to clear the cached files using one-click buttons. To get the most out of the Varnish accelerator, you can allocate a dedicated IP address to the sites that will use it.

Varnish in VPS

You can take advantage of Varnish with each of our virtual private server plans at no additional cost, since the data caching platform is pre-installed and is included by default. The sole prerequisite is that the virtual machine must be ordered with the Hepsia Control Panel, via which you’ll be able to set up Varnish for any of your Internet sites with only a couple of clicks. Each Virtual Private Server plan offers a different amount of system memory for caching purposes, but you’ll get minimum several hundred MB, which is enough even for multiple resource-heavy websites. Soon after you enable Varnish, it will start caching the content that your site visitors browse, so you will notice the significantly better webpage load speeds and the reduced load on your virtual machine very soon. The Varnish platform will permit you to use a less pricey VPS server, as you will not need that many resources to warrant the correct operation of your sites even if you have traffic-heavy sites with a lot of visitors. Optimal results are accomplished if the sites that use the Varnish platform also use a dedicated IP.

Varnish in Dedicated Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish caching platform at no extra fee and you’ll exert total control over it via a rather intuitive GUI – you’ll be able to start, to disable or to reboot an instance, to see an elaborate log, to clear the cache for any Internet site and much more. The Varnish platform will have several GB of system memory at its disposal, so even if you’ve got resource-demanding websites with a huge number of visitors, you will notice the significantly faster site loading times and the reduced load on your server. This will happen soon after you start using Varnish, as it will need some time to cache the content that users browse. You can get the most out of the platform’s potential in case the sites that are using it use also a dedicated IP address, but since your dedicated server comes with a few IPs by default, you won’t need to pay anything on top of the monthly charge for the machine itself.
