Varnish is a web application accelerator platform, which caches info for quicker access. It’s sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a visitor accesses a given web page, its content is requested by the Internet browser, and then the server processes this request and returns the necessary information. If Varnish is activated for a certain site, it will cache its pages on the first visit and if the user visits a cached page once more, the info will be delivered by the caching platform and not by the server. The accelerated loading speed is a result of the much faster response speed that Varnish offers as compared to any web server software. Of course, this doesn’t mean that the site visitors will continue being served the exact same content again and again, because any update on any of the web pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Web Hosting
If you host your Internet sites under a web hosting account with us, you will be able to add Varnish with a few clicks of the mouse from your hosting Control Panel. The platform comes as an optional upgrade with all our packages and you can choose how many websites will use it and the total storage space that will be available 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’re not linked directly to each other, so you can decide whether you want lots of memory for a single large-size website or less memory for several smaller ones. You can take advantage of the full potential of the Varnish platform if the sites use a dedicated IP. Using the hosting Control Panel, you can swiftly start/reboot/remove an instance, clear the cached content individually for each site that uses Varnish or check an elaborate log.
Varnish in Semi-dedicated Hosting
Varnish is included as standard with all Linux semi-dedicated hosting that we’re offering and you can use it for load distribution purposes. It’s available in your Hepsia hosting Control Panel. The Varnish data caching platform comes with 64 MB of system memory for cached content storing purposes and you can employ it with any Internet site that you host in the account. If you’re in need of more, you can increase the system memory allowance. The memory itself is offered in increments of 32 MB through the Upgrades section of the Control Panel. The same section will permit you to enable more instances too, if you want to use Varnish with multiple Internet sites. The two things can be ordered separately – you can cache the content of a single busy website or use a number of websites with the default memory allowance. You can get the most out of the Varnish platform in case you use a dedicated IP and you can order one with your semi-dedicated plan as well. Hepsia will give you full control over the caching platform and, with no more than one click of the mouse, you’ll be able to clear the cached data, to check a log or to restart an instance.
Varnish in Dedicated Servers Hosting
All Linux dedicated servers hosting which are ordered with the custom Hepsia hosting Control Panel come with Varnish, which is among the pre-installed software platforms that you’ll get with the server. The Varnish content caching platform can be activated and administered without efforts from the Hepsia Control Panel’s simple-to-use GUI and, with no more than one single click, you can view an elaborate log, create or restart an instance, clear the cached content associated with any website and much more. Soon after you activate the Varnish platform for a given domain or subdomain, it will start caching the webpages requested by your site visitors and as soon as it has cached enough content, you’ll observe a tremendously faster website performance and a decreased load on your server. With Varnish-dedicated memory starting at 3 GB, you will be able to use the platform for load balancing purposes even if you run multiple websites on the dedicated server.
