Varnish is a web application accelerator platform, which caches info for faster response times. It’s occasionally called an HTTP reverse proxy as well and it works between a web server and its users. When a website visitor loads a given webpage, the content is requested by the browser, and then the web server handles this request and delivers the needed data. If Varnish is enabled for a certain website, it will cache its pages at the first visit and if the visitor opens a cached page for a second time, the info will be delivered by the caching platform instead of the web server. The increased loading speed is a result of the significantly faster response speed that the Varnish platform offers as compared with any web server software. At the same time, this doesn’t mean that the website visitors will continue seeing the very same content again and again, since any modification on any of the web pages is reflected in the content that the Varnish platform caches in its system memory.

Varnish in Cloud Web Hosting

Varnish is offered as an optional upgrade with all our Linux cloud web hosting. You can add it to your account from the Hepsia hosting Control Panel, which is available with all shared packages and you will get an amazingly user-friendly graphical interface, which will give you complete control over the content caching system. Using 1-click fast-access buttons, you can reboot or terminate any of the instances, in other words – Varnish will no longer work for a specific site. You can also check an elaborate system log file or delete the cache for any of the websites. When you add Varnish to your shared hosting package, you’ll be able to choose the total amount of system memory that will be at your disposal for data caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for optimum performance, you can set a dedicated IP for the websites that will use Varnish. This will allow you to take full advantage of your Internet sites and to have a lot of satisfied visitors.

Varnish in Semi-dedicated Hosting

The Linux semi-dedicated hosting offered by us will allow you to employ Varnish once your brand new semi-dedicated account has been activated, as the data caching platform is available by default. 64 MB of system memory will be allocated to Varnish the moment your account is activated, so you can take advantage of this load balancing software once your site has been launched. In case you are in need of more system memory, you can add 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be allocated to your semi-dedicated machine momentarily. You can also increase the number of the sites that employ Varnish, or the so-called ‘instances’, which are not bound directly to the amount of system memory that you use, which suggests that you’ll have more flexibility. The platform will substantially lower the load on the server produced by your sites, so your website visitors can enjoy fast-loading web pages. You’ll be able to manage Varnish without any effort from the Control Panel using quick-access controls. You’ll be able to start/cancel any of the instances that you’ve got, to delete the cached data associated with any of your websites or to see system logs.

Varnish in Dedicated Hosting

In case you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish content caching platform at no extra cost and you will have full control over it through a really easy-to-work-with interface – you’ll be able to start, to deactivate or to reboot an instance, to view a detailed system log, to delete the cached files associated with any Internet site and much, much more. Varnish will have several GB of virtual memory at its disposal, so even if you’ve got heavy Internet sites with a vast number of visitors, you’ll notice the considerably better site loading times and the less load on your server. This will become a fact soon after you start using Varnish, as it will need a certain amount of time to cache the web pages that visitors browse. You can make the most of the platform’s potential in case the websites that are using it use also a dedicated IP, but since your dedicated server includes a few IPs by default, you will not need to pay anything on top of your monthly charge for the machine itself.
