Varnish is a web app accelerator, which has been gaining a lot of popularity lately, because it can increase the speed of any Internet site, sometimes even by 100%, based on the content itself. This tool is occasionally called an HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to improve the browsing speed for the site visitors. Each time a visitor loads a page on a certain site, the browser request is taken care of by the web server and the requested information is delivered as a response. If Varnish is enabled, it caches the web pages that the site visitor opens and in case any of them is loaded once again, it’s fetched by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator handles the web requests tremendously faster than any web server, which results in much faster browsing speeds for the site visitors. If any data is edited in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody accesses them.
Varnish in Hosting
You can make use of Varnish’s potential and accelerate your websites’ speed irrespective of the hosting plan that you’ve chosen and you can activate and set up the data caching platform with a few clicks of the mouse via the simple-to-use interface offered by our next-generation Hepsia hosting Control Panel. In the meantime, you will be able to select two separate things – how many sites will use the Varnish caching platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of memory. The latter is available in increments of 32 MB and is not linked to the number of instances, so you can add more instances and less memory and the other way around. If you have lots of content on a specific site and you gain plenty of site visitors, more system memory will give you a better result. You may also consider using a dedicated IP address for the Internet sites that will use Varnish. The Hepsia Control Panel will provide you with simple one-click buttons for deactivating or rebooting any instance, for deleting the cache associated with any Internet site and for seeing exhaustive logs.
Varnish in Semi-dedicated Hosting
The Linux semi-dedicated hosting offered by us will permit you to employ Varnish once your brand-new account has been activated, as the platform is available by default. 64 megabytes of system memory will be assigned to Varnish the moment your account is activated, so you can use this load balancing software once your website has been published to the web. In case you’re in need of more memory, you can order 32 megabytes at a time from the Hepsia Control Panel’s Upgrades section and it will be assigned to your semi-dedicated machine right away. You can also increase the number of the Internet sites that employ Varnish, or the so-called ‘instances’, which are not bound directly to the amount of memory that you use, which suggests that you’ll enjoy more flexibility. The platform will enormously lower the load on the semi-dedicated server caused by your sites, so your visitors can enjoy fast-loading web pages. You will be able to manage the Varnish caching platform with no effort from your Hepsia Control Panel using quick-access buttons. You will be able to start/remove any of the instances that you’ve got, to delete the cached data associated with any of your websites or to check system logs.
Varnish in VPS Web Hosting
We offer Varnish with all Hepsia-managed VPS web hosting, so if you obtain a server with this web hosting Control Panel, you will be able to use the caching platform at no additional fee. The Varnish platform can use different amounts of system memory for data caching purposes based on the specific server configuration that you have chosen during the order process, but at any rate, this amount will not be less than several hundred MB. This is quite enough to enhance the performance of a number of traffic-heavy sites, so the better page loading speeds and the reduced load on the virtual machine will be noticeable. The result may not be detectable straight away, as Varnish will require some time to cache the site content that visitors open, but soon after you enable it, you’ll observe its full potential. This caching platform will permit you to use a less powerful Virtual Private Server and to give less money to get the same performance you would get with a more powerful machine without Varnish.
Varnish in Dedicated Servers Hosting
All Linux dedicated servers hosting which are ordered with the custom-built Hepsia web hosting Control Panel feature Varnish, which is among the pre-installed platforms that you’ll get with the server. The Varnish content caching platform can be set up and administered without effort via the Hepsia Control Panel’s intuitive graphical interface and, with no more than one single click, you can see a detailed log, add or reboot an instance, delete the cached files for any site and much, much more. Soon after you enable Varnish for a specific domain or subdomain, it will begin caching the webpages accessed by your website visitors and as soon as it has cached enough web content, you’ll witness a considerably faster website performance in addition to a reduced load on the machine. With Varnish-dedicated virtual memory starting at 3 gigabytes, you’ll be able to use the software platform for load balancing purposes even if you host an enormous number of websites on the server.
