Varnish is a website accelerator platform, which caches information for faster response times. It is sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and a browser. When a site visitor opens a particular page, the content is requested by the web browser, and then the server processes this browser request and returns the requested info. If Varnish is enabled for a specific website, it will cache the pages on the very first visit and if the visitor accesses a cached page once more, the content will be delivered by the caching platform and not by the server. The increased speed is a result of the significantly faster response speed that the Varnish platform offers compared with any server software. At the same time, this does not mean that the site visitors will keep seeing the same content over and over again, because any update on any of the web pages is reflected in the content that Varnish stores in its system memory.
Varnish in Cloud Hosting
In case you host your sites in a cloud hosting account with us, you’ll be able to add Varnish with a few mouse clicks through your hosting Control Panel. The caching platform is offered as an optional upgrade with all our shared web hosting packages and you can choose the number of the sites that will use it and the maximum storage space that will be used for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t linked directly to each other, so you can choose if you need plenty of memory for one single large-size site or less memory for multiple smaller ones. You can take advantage of the full potential of the Varnish caching platform if the sites use a dedicated IP. With the hosting Control Panel, you can easily start/restart/delete an instance, delete the cached files independently for each website which uses Varnish or check a detailed system log.
Varnish in Semi-dedicated Hosting
Varnish is a feature, which is included as standard with all semi-dedicated hosting packages that we’re offering and you can use it for workload distribution purposes. It is available in your Hepsia hosting 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 server account. In case you’re in need of more, you can increase the memory quota. The memory itself is offered in increments of 32 megabytes through the Control Panel’s Upgrades section. The very same Upgrades section will allow you to enable more instances too, in case you want to use the Varnish platform with multiple sites. The two upgrades can be added separately – you can cache the content of one large-scale Internet site or run several different sites with the default memory allocation. You can take full advantage of the Varnish platform if you use a dedicated IP and you can order one with your semi-dedicated plan as well. Hepsia will grant you complete control over the platform and, with no more than a click, you’ll be able to clear the cached content, to see a log file or to reboot an instance.
Varnish in Dedicated Hosting
All dedicated hosting which are ordered with the custom-built Hepsia web hosting Control Panel feature Varnish, which is one of the pre-installed platforms that you will get with the dedicated server. The Varnish data caching platform can be activated and administered with no effort from Hepsia’s easy-to-navigate interface and, with no more than one single click, you can view an exhaustive log, add or restart an instance, delete the cached content associated with any Internet site and much, much more. Soon after you enable the Varnish platform for a given domain or sub-domain, it will start caching the webpages opened by your visitors and as soon as it has cached enough content, you will observe a tremendously faster site performance as well as a lowered load on the machine. With Varnish-dedicated virtual memory starting at 3 gigabytes, you will be able to use the platform for load balancing purposes even if you run numerous sites on your dedicated server.
