Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, as it can increase the speed of any Internet site, sometimes even by one hundred percent, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to accelerate the browsing speed for the site visitors. Each time a visitor accesses a page on a specific Internet site, the web browser request is taken care of by the web server and the requested content is sent as a reply. If the Varnish accelerator is activated, it caches the web pages that the website visitor opens and in case any of them is accessed once again, it’s fetched by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is modified in the meantime, the cached pages will also be updated the next time somebody attempts to open them.
Varnish in Cloud Website Hosting
Varnish comes as an optional upgrade with each of our Linux cloud website hosting
. You can add it to your hosting account from the Hepsia hosting Control Panel, which comes with all shared web hosting packages and you’ll get a quite simple-to-use interface, which will give you complete control over the data caching system. Using 1-click quick-access controls, you can reboot or remove any of the instances, in other words – Varnish will no longer be activated for a certain Internet site. You can also view a comprehensive log file or delete the cache for any of the websites. When you add Varnish to your shared hosting plan, you will be able to select the total amount of system memory that will be at your disposal for caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 MB and, for optimum performance, you can set a dedicated IP address for the sites that will use Varnish. This will allow you to take full advantage of your sites and to have many gratified visitors.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated hosting
include Varnish by default, so you can make use of the website accelerator tool and accelerate the load speed of any website that you host on our platform. You’ll get 64 megabytes of system memory dedicated to Varnish at no extra charge and you will be able to enable an instance with no more than a couple of clicks of the mouse from the Hepsia Control Panel, which comes with the semi-dedicated packages. If you need more memory, the latter is offered in increments of 32 megabytes through the Upgrades section of the Control Panel and it will be at your disposal immediately. You can also order more instances as a separate upgrade, so you can choose if a lot of data will be cached for a single website or if the available memory will be utilized by several websites. The Hepsia Control Panel will permit you to restart or to stop any instance, to see the system log for it or to clear the cached files using 1-click controls. To get the most out of the Varnish accelerator, you can get a dedicated IP address for the Internet sites which will use it.
Varnish in Dedicated Web Hosting
If you order a dedicated server
with the Hepsia Control Panel, you will acquire the Varnish data caching platform at no extra fee and you will have full control over it via a quite simple-to-navigate interface – you will be able to start, to cancel or to restart an instance, to check an in-depth system log, to delete the cached data associated with any site and much more. The Varnish platform will have several GB of system memory at its disposal, so even if you’ve got large-sized websites with multiple visitors, you’ll notice the considerably faster web page load speeds and the reduced load on your dedicated server. This will happen soon after you begin using Varnish, since it will require a certain amount of time to cache the web pages that people browse. You can make the most of the platform’s potential if the sites that are using it use also a dedicated IP, but considering the fact that your dedicated server comes with a few IPs by default, you will not need to pay anything on top of the monthly charge for the machine itself.
