Varnish is a web application accelerator platform, which caches data for quicker access. It is occasionally referred to as an HTTP reverse proxy as well and it works between a web server and its users. When a website visitor loads a given page, its content is requested by the Internet browser, and then the web server processes this browser request and delivers the required data. If Varnish is enabled for a specific website, it will cache its pages on the very first request and in case the user opens a cached page again, the info will be delivered by the accelerator platform and not by the server. The improved loading speed is an end result of the much faster response time that Varnish offers compared with any web server software. At the same time, this does not mean that the users will keep being served the exact same content again and again, since any change on any of the web pages is reflected in the content that the Varnish platform stores in its memory.

Varnish in Hosting

We offer Varnish as an optional upgrade with each Linux hosting plan and if you’d like to use it, you can add it to your shared website hosting account using the Upgrades section in your Hepsia hosting Control Panel. There are two different features that can be upgraded – the instances and the system memory. The first one depends on the number of the Internet sites that you want to employ Varnish for and the second one, which is available in increments of 32 MB, indicates the total amount of content that the platform can cache at any given time. Hepsia’s easy-to-work-with interface will allow you to shut down or to reboot any instance, to view exhaustive logs or to delete the platform’s cache with just one click. For optimal results, you can employ a dedicated IP address for the Internet sites that will use the platform. With Varnish, your website will load much faster, meaning more pleased site users and prospective customers.

Varnish in Semi-dedicated Servers

Varnish is offered by default with all semi-dedicated plans that we are offering and you can use it for workload balancing purposes. It’s available in your Hepsia Control Panel. The caching platform comes with 64 MB of system memory for cached content storing purposes and you can employ it with any website that you host in your account. If you need more than that, you can increase the system memory allocation. The memory itself is available in increments of 32 megabytes in the Upgrades section of the Control Panel. The same section will permit you to add more instances too, if you would like to use the Varnish platform with multiple Internet sites. The two upgrades can be added independently – you can cache the content of one traffic-intensive website or run several different Internet sites with the default memory allocation. You can get the most out of the Varnish caching platform in case you use a dedicated IP and you can get one with your semi-dedicated server plan as well. The Hepsia Control Panel will give you complete control over the platform and, with no more than one mouse click, you will be able to clear the cache, to view a log or to reboot an instance.

Varnish in VPS Servers

We provide Varnish with all of the Hepsia-managed VPS web hosting plans, so in case you obtain a server with this web hosting Control Panel, you’ll be able to make use of the content caching platform at no additional charge. Varnish can use different amounts of system memory for data caching purposes based on the specific sever setup that you’ve picked during the subscription process, but in any case, this amount won’t be less than several hundred MB. This is quite enough to improve the overall performance of a handful of traffic-hungry websites, so the faster site load speeds and the lowered load on the VPS will be perceivable. The result may not be observable instantly, since the Varnish platform will require some time to cache the website content that users access, but soon after you set it up, you’ll feel its full potential. This platform will permit you to use a less powerful server and to pay less money to get the exact same performance you’d get with a higher-end virtual machine without Varnish.

Varnish in Dedicated Servers

You can employ Varnish in order to enhance the load speed of any website that is hosted on a dedicated server with us if the Hepsia hosting Control Panel is installed on the machine. Not only will you get the caching platform ready for use at no extra charge, but you’ll also exert full control over it through the Hepsia Control Panel’s intuitive GUI. It will take just one single mouse click to start or cancel an instance or to clear the cached data associated with any Internet site that’s using Varnish and if you’re more sophisticated, you can also check the platform’s system logs. Varnish comes with at least 3 GB of virtual memory for site content caching purposes, so even if you run a vast number of Internet sites on your dedicated server and they all use the caching platform, the improvement in their performance will be detectable. You will just need to wait for a little while until Varnish caches whatever pages the site visitors access on their end. The platform performs best when the websites use a dedicated IP address, but since our servers include 3 free-of-charge IP addresses, you’ll have all that you need.
