Varnish is a web application accelerator platform, which caches information for faster access. It is occasionally referred to as a caching HTTP reverse proxy too and it works between a web server and a browser. When a visitor loads a particular web page, the content is requested by the Internet browser, and then the server handles this request and delivers the necessary info. If Varnish is enabled for a website, it will cache the pages at the very first request and if the user accesses a cached page once again, the info will be delivered by the accelerator platform instead of the web server. The accelerated loading speed is an end result of the significantly faster response speed that Varnish offers as compared with any web server software. Of course, this doesn’t mean that the website visitors will keep being served the very same content again and again, as any modification on any of the pages is reflected in the content that Varnish caches in its system memory.
Varnish in Cloud Website Hosting
In case you host your sites under a cloud website hosting account with us, you will be able to activate Varnish with a couple of mouse clicks through your hosting Control Panel. The content caching platform is available as an optional upgrade with all our hosting plans and you can select how many websites will use it and the maximum storage space that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they are not linked directly to each other, so you can choose whether you want plenty of memory for one large-scale website or less memory for several smaller ones. You can unleash the full potential of Varnish if the websites use a dedicated IP. With the Control Panel, you can effortlessly start/restart/terminate an instance, delete the cached data individually for each site which uses the Varnish platform or see an exhaustive system log file.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers include Varnish by default, so you can take full advantage of the web application accelerator tool and increase the loading speed of any site that you host on our platform. You’ll get 64 megabytes of system memory exclusively for Varnish at no additional cost and you will be able to enable an instance with no more than a few clicks of the mouse through the Hepsia hosting Control Panel, which is included with the semi-dedicated plans. In case you need more memory, the latter is available in increments of 32 MB through the Control Panel’s Upgrades section and it will be at your disposal straight away. You can also order more instances as a separate upgrade, so you can decide whether lots of data will be cached for a single site or whether the memory will be used by several Internet sites. The Hepsia Control Panel will permit you to reboot or to shut down any instance, to see the system log file for it or to delete the cached data using 1-click buttons. To take full advantage of Varnish, you can set a dedicated IP for the sites which will employ it.
Varnish in VPS Servers
Varnish is included by default with all Linux VPS servers that we offer on the condition that the virtual server is ordered with the Hepsia Control Panel, so you can optimize the overall performance of your websites with just a few clicks of the mouse. The more powerful the package, the more system memory Varnish will have at its disposal, but even with a less powerful package, the platform will be able to utilize several hundred megabytes, so even if you own several different sites, you’ll notice a significant decrease in the server load and a much better webpage load speed. The Varnish platform will need to work for a little while while the users navigate the website and as soon as the site content has been cached, you’ll perceive the effects. One of the upsides of employing Varnish is that a less powerful and less pricey VPS package will do the very same job as a more high-priced one without the platform, so not only will your sites perform better, but you will also spare a certain amount of cash.
Varnish in Dedicated Servers
If you want the most powerful web hosting solution and you order any of the Linux dedicated servers that we’re offering, you will be able to use the Varnish platform to enhance the work of your Internet sites at no additional cost on the condition that the dedicated server is ordered with our cutting-edge Hepsia Control Panel. Its easy-to-use GUI will permit you to keep track of system processes, to clear the cached content or to restart any instance with one single mouse click. The minimum amount of system memory that Varnish can employ to cache site content is 3 GB, which is more than enough for an enormous number of resource-hungry sites, so your dedicated server will be able to handle a massive load while your website visitors are having a seamless browsing experience. Since your dedicated machine will come with a number of dedicated IP addresses, you’ll be able to use Varnish’s full capacity.
