Varnish is a website accelerator tool, which has been gaining a lot in popularity in recent years, because 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 reduce the overall load on the server and to boost the access speed for the website visitors. Whenever a visitor opens a page on a certain Internet site, the web browser request is handled by the web server and the requested content is returned as a reply. If the Varnish accelerator is activated, it caches the pages that the visitor opens and if any of them is opened once more, it is delivered by Varnish and not by the web server directly. The improvement in the overall performance comes from the fact that the accelerator handles the web requests substantially quicker than any web server, which results in much faster browsing speeds for the users. If any data is edited in the meantime, the cached web pages will also be updated the next time somebody attempts to open them.
Varnish in Shared Web Hosting
In case you host your sites in a shared web hosting account with us, you’ll be able to add Varnish with a few clicks of the mouse from your Control Panel. The platform is offered as an upgrade with all our web hosting plans and you can select how many websites will use it and the total storage space that will be used for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they aren’t directly linked to each other, so you can choose if you want plenty of memory for a single large website or less memory for multiple smaller ones. You can unlock the full potential of the Varnish platform if the websites use a dedicated IP. Using the Control Panel, you can swiftly start/restart/remove an instance, clear the cached content individually for each website that employs the Varnish platform or view a comprehensive system log file.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers come with Varnish by default, so you can make use of the web app accelerator and optimize the speed of any site that you host on our semi-dedicated servers. You’ll get 64 megabytes of system memory exclusively for the Varnish accelerator at no additional cost and you’ll be able to enable an instance with no more than a couple of clicks from the Hepsia Control Panel, which is included with the semi-dedicated packages. In case you need more memory, the latter is offered in increments of 32 MB in the Upgrades section of the Control Panel and it will be at your disposal instantaneously. You can also add more instances as an upgrade, so you can decide if lots of content will be cached for one website or if the available memory will be utilized by different websites. The Hepsia Control Panel will permit you to reboot or to terminate any instance, to view the system log associated with it or to delete the cached content using single-click buttons. To take full advantage of Varnish, you can assign a dedicated IP address to the Internet sites which will use it.
Varnish in VPS Servers
The Varnish content caching platform is included by default with each of the VPS servers that we’re offering on the condition that the VPS server is ordered with the Hepsia Control Panel, so you can optimize the performance of your sites with just a couple of clicks of the mouse. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a low-end plan, the caching platform will be able to utilize several hundred megabytes, so even if you’ve got several websites, you’ll notice a serious decrease in the server load and a considerably faster website loading speed. The Varnish caching platform will need to work for a little while as the users browse the site and once the site content has been cached, you will perceive the effect. One of the benefits of employing Varnish is that a less powerful and less expensive Virtual Private Server plan will accomplish the very same job as a more expensive one without the platform, so not only will your Internet sites perform considerably better, but you will also spare a certain amount of cash.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia hosting Control Panel, you will acquire the Varnish platform at no additional charge and you will have total control over it via an amazingly easy-to-use GUI – you will be able to start, to remove or to restart an instance, to see a detailed log, to delete the cached data associated with any Internet site and much, much more. Varnish will have several gigabytes of system memory at its disposal, so even if you’ve got resource-hungry Internet sites with a vast number of visitors, you will notice the significantly faster website loading speeds and the less load. This will happen shortly after you begin using Varnish, as it will need a certain amount of time to cache the site content that visitors request. You can make the most of the platform’s capabilities in case the sites that are using it also use a dedicated IP address, but considering the fact that your server includes a few IP addresses by default, you won’t need to pay anything on top of the monthly charge for the machine itself.
