Varnish is a website accelerator, which has been gaining a lot in popularity lately, as it can increase the loading speed of any website, at times even by one hundred percent, based on the content itself. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to accelerate the browsing speed for the website visitors. Every time a visitor loads a page on a certain Internet site, the browser request is taken care of by the web server and the requested content is sent as a response. If the Varnish accelerator is activated, it caches the pages that the website visitor opens and in case any of them is opened for a second time, it is delivered by Varnish and not by the server directly. The performance boost comes from the fact that the accelerator processes the browser requests tremendously faster than any web server, which leads to much faster browsing speeds for the site visitors. In case any content is changed meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody opens them.
Varnish in Cloud Hosting
You can take advantage of Varnish’s full potential and boost your websites’ speed regardless of the cloud hosting plan that you have chosen and you can enable and configure the data caching platform with a couple of clicks of the mouse from the easy-to-use GUI offered by our cutting-edge Hepsia hosting Control Panel. During the process, you will be able to select two separate things – how many Internet sites will employ the Varnish platform, i.e. the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can add more instances with less memory and the other way around. If you’ve got a lot of content on a particular Internet site and you get plenty of site visitors, more system memory will give you a better result. You may also consider using a dedicated IP for the websites that will use the Varnish platform. Hepsia will offer you easy one-click buttons for terminating or rebooting any instance, for clearing the cache for any Internet site and for seeing exhaustive system logs.
Varnish in Semi-dedicated Servers
Varnish comes by default with all Linux semi-dedicated hosting plans that we’re offering and you can use it for workload distribution purposes. It is available in your Hepsia Control Panel. The content caching platform comes with 64 MB of system memory for cached data storing purposes and you can use it with any site that you host in the semi-dedicated account. If you are in need of more, you can increase the memory allocation. The memory itself is available in increments of 32 megabytes through the Upgrades section of the Control Panel. The very same Upgrades section will allow you to activate more instances as well, in case you want to use Varnish with more websites. The two things can be added separately – you can cache the content of one single resource-consuming site or use a number of sites with the default memory allowance. You can take full advantage of the Varnish caching platform in case you’ve got a dedicated IP address and you can order one with your semi-dedicated server package as well. Hepsia will give you complete control over the platform and, with no more than one mouse click, you’ll be able to delete the cache, to check a system log file or to reboot an instance.
Varnish in VPS Servers
You can use Varnish with each of our VPS server plans at no extra cost, as the data caching platform is pre-installed and is offered by default. The sole requirement is that the virtual machine must be ordered with the Hepsia Control Panel, via which you’ll be able to activate Varnish for any of your sites with only a few clicks of the mouse. Each VPS plan features a different amount of system memory for caching purposes, but you will get no less than several hundred MB, which is quite enough even for several traffic-consuming sites. Soon after you set up the Varnish platform, it’ll start caching the content that your visitors open, so you will notice the tremendously faster Internet site loading speeds and the lowered load on the Virtual Private Server in no time. The Varnish platform will allow you to use a less high-priced virtual machine, as you won’t require that many resources to guarantee the proper operation of your sites even if you own resource-consuming sites with numerous visitors. Best results are achieved if the sites which use Varnish use also a dedicated IP address.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain Varnish at no extra charge and you will have complete control over it via a truly easy-to-work-with interface – you will be able to start, to remove or to restart an instance, to browse an in-depth log, to clear the cached content associated with any Internet site and much, much more. The Varnish caching platform will have several gigabytes of memory at its disposal, so even if you own resource-requiring Internet sites with multiple visitors, you’ll notice the considerably faster site load times and the decreased server load. This will become a fact shortly after you start using the Varnish platform, as it will need a certain amount of time to cache the web pages that users browse. You can take full advantage of the platform’s capabilities if the sites that are using it also use a dedicated IP, but since your server includes a couple of IP addresses by default, you will not need to pay anything on top of your monthly charge for the machine itself.
