Varnish is a web accelerator tool, which has been gaining a lot in popularity lately, because it can increase the speed of any Internet site, sometimes even by one hundred percent, depending on the content. This tool is occasionally called an HTTP reverse proxy as well and is used to reduce the overall load on the physical server and to boost the browsing speed for the website visitors. Anytime a visitor accesses a page on a certain website, the browser request is handled by the web server and the requested information is served as a response. If the Varnish accelerator is enabled, it caches the pages that the website visitor opens and in case any of them is loaded for a second time, it is served by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator handles the browser requests significantly faster than any web server, which results in much faster browsing speeds for the website visitors. In case any data is changed in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody tries to access them.
Varnish in Shared Hosting
In case you host your sites under a shared hosting account with us, you will be able to activate Varnish with a couple of clicks from your hosting Control Panel. The platform is available as an optional upgrade with all our shared hosting plans and you can select the number of the sites that will use it and the maximum storage space that will be used for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they aren’t directly linked to each other, so you can choose whether you want lots of memory for a single large-size website or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish if the sites use a dedicated IP address. Using the hosting Control Panel, you can effortlessly start/restart/terminate an instance, delete the cached data individually for each site that uses Varnish or see a comprehensive system log.
Varnish in Semi-dedicated Servers
All our Linux semi-dedicated servers come with Varnish by default, so you can make full use of the website accelerator tool and optimize the speed of any site that you host on our platform. You’ll get 64 megabytes of memory dedicated to the Varnish accelerator at no additional charge and you will be able to activate 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 want more memory, the latter is available in increments of 32 MB through the Upgrades section of the Control Panel and it will be available to you right away. You can also add more instances as a separate upgrade, so you can decide if plenty of content will be cached for a single website or whether the memory will be used by several Internet sites. The Hepsia Control Panel will enable you to reboot or to delete any instance, to check the system log file associated with it or to delete the cached data using single-click controls. To take full advantage of Varnish, you can get a dedicated IP address for the sites that will employ it.
Varnish in VPS Servers
You can use Varnish with each of our VPS server packages at no additional charge, since the platform is pre-installed and is included by default. The one and only prerequisite is that the virtual machine must come with the Hepsia Control Panel, through which you will be able to set up Varnish for any of your sites with only a couple of clicks. Each Virtual Private Server plan features a different amount of memory for data caching purposes, but you’ll get no less than several hundred MB, which is sufficient even for several frequently visited websites. Shortly after you enable the Varnish platform, it will start caching the content that your visitors request, so you’ll notice the much better webpage loading times and the reduced load on the virtual server very soon. Varnish will permit you to use a less high-priced virtual server, as you will not need that much power to sustain the uninterrupted operation of your websites even if you own large-sized sites with multiple visitors. Optimum results are accomplished if the websites which use the Varnish platform use also a dedicated IP address.
Varnish in Dedicated Servers
If you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire Varnish at no additional charge and you will have total control over it via an incredibly time and effort saving GUI – you’ll be able to start, to remove or to restart an instance, to view an elaborate log, to clear the cached files associated with any Internet site and much, much more. The Varnish caching platform will have several gigabytes of memory at its disposal, so even if you host regularly visited sites with multiple visitors, you will notice the considerably faster website load speeds and the decreased server load. This will happen shortly after you begin using Varnish, since it will need some time to cache the pages that people browse. You can make the most of the platform’s potential if the websites that are using it use also a dedicated IP, 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 server itself.
