Varnish is a web application accelerator platform, which caches info for faster access. It’s occasionally referred to as a caching HTTP reverse proxy too and it works between a web server and a browser. When a website visitor accesses a specific page, the content is requested by the Internet browser, and then the server processes this request and returns the needed data. If Varnish is activated for a certain website, it will cache the pages on the first request and in case the user accesses a cached page for a second time, the data will be delivered by the caching platform and not by the web server. The accelerated speed is an end result of the considerably faster response speed that Varnish offers compared with any server software. Of course, this doesn’t mean that the users will continue being served the same content over and over again, because any update on any of the web pages is reflected in the content that the Varnish platform saves in its memory.
Varnish in Cloud Website Hosting
You can make use of Varnish’s full potential and accelerate your sites irrespective of the cloud website hosting plan that you’ve selected and you can enable and set up the platform with a few clicks via the user-friendly GUI offered by our leading-edge Hepsia hosting Control Panel. During the procedure, you’ll be able to choose two different things – how many websites will use the Varnish platform, i.e. the number of instances, and how much content will be cached, in other words – the amount of system memory. The latter is available in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances and less memory and the other way around. In case you’ve got plenty of content on a particular Internet site and you receive many website visitors, more memory will guarantee you a better result. You may also consider using a dedicated IP for the sites that will use Varnish. Hepsia will provide you with simple 1-click controls for deactivating or restarting any instance, for erasing the cache for each website and for seeing in-depth logs.
Varnish in Semi-dedicated Servers
The semi-dedicated servers that we offer will permit you to use Varnish as soon as your brand-new account has been opened, as the content caching platform comes by default. 64 megabytes of system memory will be assigned to Varnish the moment your account is activated, so you can make use of this load balancing software as soon as your site has been published online. If you are in need of more memory, you can get 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated machine instantly. You can also increase the number of the websites that employ Varnish, or the so-called ‘instances’, which are not directly bound to the amount of system memory that you use, which suggests that you’ll enjoy more versatility. The platform will enormously lower the load produced by your websites, so your site visitors can enjoy fast-loading pages. You’ll be able to manage the Varnish platform without effort through your Control Panel using quick-access buttons. You’ll be able to start/cancel any of the instances that you’ve got, to clear the cached data associated with any of your websites or to view system log files.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you will get Varnish at no extra charge and you’ll exert complete control over it via a rather intuitive graphical interface – you’ll be able to start, to stop or to reboot an instance, to see a detailed system log, to delete the cached data associated with any website and much, much more. Varnish will have several gigabytes of system memory at its disposal, so even if you’ve got traffic-hungry Internet sites with a lot of visitors, you’ll notice the significantly better site loading speeds and the lowered load on the dedicated server. This will happen shortly after you start using the Varnish platform, as it will require a certain amount of time to cache the web pages that visitors request. You can take full advantage of the platform’s capabilities if the Internet sites that are using it also use a dedicated IP address, but owing to the fact that your server includes several IP addresses by default, you won’t have to pay anything on top of your monthly charge for the server itself.
