Varnish is a web application accelerator platform, which caches information for quicker access. It is sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a visitor opens a given web page, the content is requested by the web browser, and then the server handles this request and delivers the required information. If Varnish is enabled for a particular website, it will cache the pages at the first request and if the visitor accesses a cached page again, the info will be delivered by the caching platform instead of the web server. The increased load speed is a result of the considerably faster response time that the Varnish platform offers as compared with any server software. Of course, this doesn’t mean that the users will keep seeing the exact same content again and again, as any update on any of the web pages is reflected in the content that Varnish stores in its system memory.
Varnish in Shared Hosting
You can use Varnish’s potential and increase the loading speed of your sites regardless of the shared hosting package that you have picked and you can add and set up the data caching platform with a few clicks of the mouse from the simple-to-work-with GUI offered by our innovative Hepsia Control Panel. In the meantime, you will be able to choose two different things – how many sites will use Varnish, in other words – the number of instances, and how much information will be cached, in other words – the amount of memory. The latter is available in increments of 32 MB and is not tied to the number of instances, so you can add more instances with less memory and vice versa. If you have a lot of content on a given site and you win lots of website visitors, more system memory will give you a better result. You may also consider employing a dedicated IP for the websites that will use Varnish. Hepsia will offer you simple 1-click controls for turning off or rebooting any instance, for erasing the cache associated with each website and for viewing in-depth system logs.
Varnish in Semi-dedicated Servers
Varnish comes as standard with all semi-dedicated plans that we are offering and you can use it for workload distribution purposes. It’s available in your Hepsia Control Panel. The Varnish platform comes with 64 megabytes of system memory for cached data storing purposes and you can employ it with any Internet site that you host in your semi-dedicated server account. If you are in need of more, you can increase the system memory allowance. The memory itself is available in increments of 32 megabytes in the Control Panel’s Upgrades section. The very same Upgrades section will enable you to enable more instances too, if you wish to use Varnish with more sites. The two upgrades can be ordered independently – you can cache the content of one traffic-heavy Internet site or run several websites with the default memory. 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 package as well. Hepsia will grant you total control over the platform and, with no more than one click of the mouse, you will be able to clear the cached files, to check a log file or to reboot an instance.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you will acquire Varnish at no extra cost and you will have full control over it through an extremely time and effort saving graphical interface – you’ll be able to start, to remove or to restart an instance, to browse an in-depth log, to clear the cached data for any site and much, much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you host resource-consuming Internet sites with a lot of visitors, you will notice the tremendously faster page load times and the less load on the server. This will happen soon after you start using the Varnish platform, as it will require a certain amount of time to cache the pages that visitors open. You can make the most of the platform’s capacity if the sites that are using it also use a dedicated IP address, but since your dedicated server includes a couple of IP addresses by default, you will not need to pay anything on top of the monthly charge for the machine itself.
