Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the loading speed of any website, sometimes even by 100 percent, depending on the content. This tool is sometimes called a caching HTTP reverse proxy too and is used to lower the overall server load and to increase the access speed for the website visitors. Anytime a visitor opens a page on a given site, the browser request is taken care of by the web server and the requested data is sent as a reply. If Varnish is activated, it caches the web pages that the website visitor browses and in case any of them is accessed once more, it’s delivered by Varnish and not by the server directly. The improvement in the performance comes from the fact that the accelerator handles the web requests significantly quicker than any web server, which leads to much faster browsing speeds for the site visitors. If any content is modified in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody accesses them.

Varnish in Shared Website Hosting

In case you host your Internet sites under a shared website hosting account with us, you’ll be able to activate Varnish with a couple of clicks of the mouse through your Control Panel. The platform comes as an optional upgrade with all our web hosting packages and you can select the number of the websites that will use it and the maximum 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 number of instances and the amount of system memory and they’re not directly tied to each other, so you can choose whether you want lots of memory for a single large-sized website or less memory for multiple smaller ones. You can unleash the full potential of the Varnish caching platform if the websites use a dedicated IP address. Using the Control Panel, you can easily start/reboot/stop an instance, delete the cached contents independently for each site which employs Varnish or check an exhaustive log file.

Varnish in Semi-dedicated Servers

All our semi-dedicated hosting plans include Varnish by default, so you can take full advantage of the web application accelerator tool and accelerate any site that you host on our platform. You’ll get 64 megabytes of system memory exclusively for Varnish at no additional cost and you’ll be able to create an instance with no more than a couple of clicks from the Hepsia Control Panel, which comes with the semi-dedicated server plans. If you want 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 straight away. You can also order more instances as a separate upgrade, so you can choose if lots of data will be cached for a single site or whether the available memory will be utilized by multiple sites. The Hepsia Control Panel will allow you to restart or to disable any instance, to check the system log for it or to delete the cached files using one-click controls. To take full advantage of Varnish, you can set a dedicated IP for the websites that will employ it.

Varnish in VPS Servers

You can take full advantage of the load balancing capabilities of Varnish with each of our VPS hosting plans if you select Hepsia as your web hosting Control Panel. The Varnish caching platform comes by default and the memory that it’ll be able to use to cache your website content depends upon the specific VPS plan that you’ve selected, but even with the lower-end plans, you’ll have at least several hundred megabytes of memory at your disposal exclusively for caching purposes. This amount is sufficient enough to optimize the overall performance of multiple sites. It’ll take a little time for you to see the results, since Varnish caches the content that website visitors open, but soon after that you will notice the significantly decreased load on your Virtual Private Server and the accelerated Internet site browsing speed. The Varnish platform will permit you to make use of a less powerful package for sites that would usually need a more costly hosting service.

Varnish in Dedicated Servers

You can use Varnish to enhance the speed of any site that is hosted on a dedicated server with us if the Hepsia Control Panel is pre-installed on it. Not only will you get the caching platform ready for use at no additional cost, but you will also have total control over it through Hepsia’s intuitive graphical interface. It’ll take just one click to start or delete an instance or to delete the cached data for any website that is using Varnish and if you are more trained, you can also see the platform’s system logs. Varnish comes with at least 3 gigabytes of virtual memory for web content caching purposes, so even if you run a huge number of Internet sites on your dedicated server and they all use the caching platform, the difference in their overall performance will be perceivable. You’ll just have to wait for a while until Varnish caches whatever web pages the visitors access on their end. The Varnish platform performs best if the websites use a dedicated IP, but due to the fact that our dedicated servers come with three free IP addresses, you’ll have all that you need.
