Learn exactly what Varnish is. Get to know much more about web accelerators and their purpose.
Varnish is a web accelerator, which has been gaining a lot of popularity lately, as it can increase the speed of any website, sometimes even by 100 percent, depending on the content itself. This tool is sometimes called an HTTP reverse proxy too and is used to decrease the overall load on the physical server and to enhance the access speed for the site visitors. Whenever a visitor accesses a page on a given Internet site, the browser request is handled by the web server and the requested content is delivered as a response. If Varnish is enabled, it caches the pages that the visitor browses and if any of them is accessed once again, it is delivered by Varnish and not by the web server directly. The increase in the performance is due to the fact that the accelerator processes the browser requests considerably quicker than any web server, which leads to much faster browsing speeds for the website visitors. In case any data is edited meanwhile, the cached pages will also be updated the next time someone attempts to access them.
Varnish in Website Hosting
Varnish comes as an optional upgrade with all our website hosting
. You can add it to your hosting account via the Hepsia hosting Control Panel, which is available with all shared web hosting plans and you will get a rather simple-to-work-with GUI, which will give you complete control over the content caching platform. Using one-click fast-access controls, you can reboot or remove any of the instances, in other words – Varnish will no longer be enabled for a given website. You can also view an exhaustive log file or clear the cache associated with any of the websites. When you add Varnish to your hosting package, you’ll be able to choose the maximum amount of system memory that will be at your disposal for caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 MB and, for best performance, you can get a dedicated IP address for the websites that will use Varnish. This will enable you to get the most out of your sites and to have lots of gratified website users.
Varnish in Semi-dedicated Servers
Varnish is included as standard with all semi-dedicated servers
offered by us and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any site that you host in the semi-dedicated account. If you need more, you can increase the memory allocation. The memory itself is available in increments of 32 megabytes through the Control Panel’s Upgrades section. The very same section will enable you to activate more instances too, in case you would like to use Varnish with more websites. The two things can be ordered separately – you can cache the content of one large site or run a number of sites with the default memory allocation. You can take full advantage of the Varnish caching platform if you use a dedicated IP address and you can order one with your semi-dedicated package as well. The Hepsia Control Panel will grant you total control over the platform and, with no more than one click of the mouse, you’ll be able to delete the cached data, to see a log or to reboot an instance.
Varnish in Dedicated Servers
If you order a dedicated server
with the Hepsia hosting Control Panel, you’ll get the Varnish caching platform at no extra fee and you will have total control over it through a rather simple-to-navigate graphical interface – you’ll be able to start, to terminate or to reboot an instance, to view an elaborate log, to clear the cache for any site and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you have resource-consuming Internet sites with an enormous number of visitors, you will notice the significantly faster page load speeds and the decreased load on your server. This will happen soon after you begin using Varnish, as it will need a certain amount of time to cache the website content that users access. You can make the most of the platform’s potential if the sites that are using it also use a dedicated IP address, but owing to the fact that your server comes with a few IP addresses by default, you won’t need to pay anything on top of the monthly fee for the machine itself.
