Varnish is a web application accelerator platform, which caches content for the sake of quicker access. It’s sometimes called an HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a website visitor accesses a given web page, its content is requested by the browser, and then the web server handles this browser request and delivers the necessary information. If Varnish is enabled for a certain site, it will cache its pages on the very first request and in case the visitor accesses a cached page for a second time, the content will be delivered by the caching platform and not by the web server. The increased load speed is an end result of the considerably faster response time that the Varnish platform offers as compared to any server software. Of course, this does not mean that the site visitors will keep seeing the very same content over and over again, because any modification on any of the web pages is reflected in the content that the Varnish platform keeps in its system memory.

Varnish in Shared Website Hosting

Varnish is available as an optional upgrade with each shared website hosting plan and if you would like to use it, you can add it to your account through the Upgrades menu in your Hepsia hosting Control Panel. There are two separate things that can be upgraded – the number of instances and the system memory. The first one depends on the number of the websites that you would like to employ Varnish for and the second one, which is offered in increments of 32 MB, indicates the total amount of data that the data caching platform can cache at any given time. The Hepsia Control Panel’s easy-to-work-with GUI will enable you to shut down or to reboot any instance, to view exhaustive system logs or to clear the platform’s cache with just click of the mouse. For maximum results, you can employ a dedicated IP address for the websites that will use the platform. With Varnish, your Internet site will load substantially faster, which means more happy visitors and potential customers.

Varnish in Semi-dedicated Servers

All our Linux semi-dedicated servers come with Varnish by default, so you can use the accelerator and increase the load speed of any website that you host on our semi-dedicated servers. You will get 64 MB of memory exclusively for the Varnish accelerator at no additional cost and you will be able to create an instance with no more than a few clicks through the Hepsia hosting Control Panel, which comes with the semi-dedicated server packages. In case you need more memory, the latter is available in increments of 32 MB in the Control Panel’s Upgrades section and it will be at your disposal straight away. You can also order more instances as an upgrade, so you can choose whether plenty of data will be cached for one website or whether the memory will be utilized by multiple websites. The Hepsia Control Panel will permit you to restart or to terminate any instance, to check the system log for it or to clear the cached data using one-click controls. To get the most out of the Varnish accelerator, you can set a dedicated IP for the Internet sites that will employ it.

Varnish in VPS Servers

The Varnish platform is included by default with all VPS servers that we are offering on the condition that the virtual server is ordered with the Hepsia Control Panel, so you can improve the performance of your sites with only a few clicks of the mouse. The more powerful the plan, the more system memory will be available to Varnish, but even with a low-end package, the platform will be able to utilize several hundred megabytes, so even if you run several websites, you will notice a significant reduction in the server load and a considerably faster webpage loading speed. The platform will have to work for a while while the users navigate the web pages and once the website content has been cached, you’ll distinguish the results. One of the advantages of employing Varnish is that a lower-end and less costly VPS plan will do the exact same job as a more high-priced one without the caching platform, so not only will your websites work significantly better, but you’ll also save a certain amount of money.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you’ll get the Varnish data caching platform at no extra fee and you will have total control over it through a very user-friendly interface – you will be able to start, to stop or to restart an instance, to see a detailed log, to delete the cached content for any site and much, much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you’ve got large-size websites with multiple visitors, you will notice the much faster website loading speeds and the lowered load on your dedicated server. This will become a fact shortly after you begin using Varnish, as it will need some time to cache the website content that visitors open. You can make the most of the platform’s capabilities if the websites that are using it use also a dedicated IP address, but due to the fact that your dedicated server includes a couple of IPs by default, you won’t have to pay anything on top of the monthly fee for the machine itself.
