Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any website, sometimes even by one hundred percent, depending on the content itself. This tool is occasionally referred to as an HTTP reverse proxy too and is used to decrease the overall server load and to accelerate the browsing speed for the website visitors. Every time a visitor accesses a page on a certain site, the browser request is handled by the web server and the requested info is delivered as a response. If the Varnish accelerator is enabled, it caches the web pages that the website visitor browses and if any of them is opened once again, it’s served by Varnish and not by the web server directly. The boost in the overall performance is due to the fact that the accelerator processes the browser requests considerably quicker than any web server, which results in much faster browsing speeds for the users. If any content is edited meanwhile, the cached pages will also be updated the next time somebody tries to open them.
Varnish in Cloud Website Hosting
Varnish is offered as an optional upgrade with each Linux cloud website hosting package
and if you’d like to use it, you can add it to your shared account via the Upgrades section in your Hepsia Control Panel. There are two separate features that can be upgraded – the number of instances and the memory. The first one depends on the number of the websites that you wish to use Varnish for, whereas the second, which is offered in increments of 32 megabytes, shows the maximum amount of content that the platform can store at any particular time. The Hepsia Control Panel’s easy-to-use interface will allow you to shut down or to reboot any instance, to view in-depth system logs or to erase the platform’s cache with just one mouse click. For best results, you can use a dedicated IP address for the websites that will use the platform. With Varnish, your Internet site will open significantly faster, which means more pleased visitors and prospective clients.
Varnish in Semi-dedicated Hosting
Varnish is part of the default service set that you will receive if you decide to host your sites under a semi-dedicated server
account. You can configure it for any of your Internet sites through our advanced Hepsia Control Panel. The default system memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this caching platform at the same time. As these two features aren’t linked to each other, you can use a couple of sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for one single Internet site. The Varnish platform performs best if you assign a dedicated IP to the websites that utilize its power. The Hepsia Control Panel will provide you with a simple way of rebooting any instance. On top of that, you’ll be able to clear the cached data with only one single mouse click.
Varnish in VPS Web Hosting
You can take advantage of Varnish with any of our virtual private server
plans at no extra cost, as the caching platform is pre-installed and is offered by default. The only prerequisite is that the VPS server must be ordered with the Hepsia hosting Control Panel, via which you’ll be able to activate Varnish for any of your sites with just a few mouse clicks. Each Virtual Private Server plan includes a different amount of system memory for caching purposes, but you’ll get no less than several hundred megabytes, which is quite enough even for several large websites. Shortly after you activate the Varnish platform, it will start caching the content that your visitors access, so you’ll notice the tremendously better webpage loading times and the lowered load very soon. Varnish will permit you to use a less expensive Virtual Private Server, since you won’t require that much power to sustain the proper operation of your Internet sites even if you manage high-demand sites with numerous visitors. Maximum results are achieved if the Internet sites that use Varnish also use a dedicated IP.
