Learn exactly what Varnish is. Get to know a lot more about web accelerators and their function.
Varnish is a web application accelerator platform, which caches content for the sake of faster response times. It’s sometimes called an HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a website visitor accesses a specific web page, the content is requested by the browser, and then the server handles this request and sends back the necessary data. If Varnish is enabled for a specific website, it will cache the pages at the very first request and if the visitor visits a cached page once more, the data will be delivered by the accelerator platform and not by the web server. The increased loading speed is a result of the much faster response time that the Varnish platform offers compared to any web server software. At the same time, this does not mean that the visitors will keep being served the very same content over and over again, as any change on any of the web pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Shared Website Hosting
You can unlock Varnish’s full potential and accelerate the speed of your sites irrespective of the shared website hosting
package that you have picked and you can enable and configure the content caching platform with a few mouse clicks using the easy-to-use interface offered by our leading-edge Hepsia Control Panel. In the meantime, you’ll be able to choose two different things – how many Internet sites will use Varnish, in other words – the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not linked to the number of instances, so you can order more instances and less memory and vice versa. If you’ve got a lot of content on a given Internet site and you get plenty of website visitors, more system memory will give you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish platform. The Hepsia Control Panel will provide you with easy 1-click buttons for disabling or restarting any instance, for erasing the cache associated with any website and for seeing in-depth system logs.
Varnish in Semi-dedicated Servers
Varnish is included as standard with all semi-dedicated hosting plans
that we’re offering and you can use it for load distribution purposes. It’s available in your Hepsia Control Panel. The Varnish data caching platform comes with 64 MB of system memory for cached content storing purposes and you can use it with any Internet site that you host in the semi-dedicated server account. In case you’re in need of more than that, you can increase the memory allowance. The memory itself is available in increments of 32 MB in the Control Panel’s Upgrades section. The very same section will enable you to add more instances too, in case you want to use Varnish with more sites. The two upgrades can be ordered independently – you can cache the content of a single large-size Internet site or use several Internet sites with the default memory quota. You can get the most out of Varnish in case you’ve got a dedicated IP and you can order one with your semi-dedicated server plan as well. The Hepsia Control Panel will grant you total control over the caching platform and, with no more than one mouse click, you will be able to clear the cached content, to see a log file or to restart an instance.
Varnish in Dedicated Servers
If you want a more powerful website hosting solution and you order one of the dedicated web hosting plans
that we’re offering, you will be able to use the Varnish data caching platform to boost the overall performance of your sites at no additional cost as long as the server is ordered with our advanced Hepsia Control Panel. Its user-friendly graphical interface will allow you to keep track of platform processes, to clear the cache or to restart any instance with one single mouse click. The smallest amount of system memory that the caching platform can employ to cache Internet site content is 3 GB, which is quite enough for a vast collection of high-demand sites, so your server will be able to deal with a substantial load while your Internet site visitors are having a smooth browsing experience. Since your dedicated machine will include several different dedicated IPs, you’ll be able to make use of Varnish’s maximum potential.
