Varnish is a web app accelerator, which has been gaining a lot in popularity in recent years, because it can increase the speed of any Internet site, at times even by 100%, based on the content. This tool is sometimes called a caching HTTP reverse proxy as well and is used to decrease the overall server load and to improve the access speed for the site visitors. Each time a visitor accesses a page on a given Internet site, the web browser request is processed by the web server and the requested data is sent as a response. If Varnish is activated, it caches the web pages that the site visitor opens and if any of them is loaded once again, it’s served by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator handles the browser requests tremendously quicker than any web server, which results in much faster browsing speeds for the site visitors. If any data is edited in the meantime, the cached pages will also be ‘refreshed’ the next time someone opens them.
Varnish in Shared Hosting
Varnish is available as an optional upgrade with each Linux shared hosting and if you would like to use it, you can add it to your web hosting account via the Upgrades section in your Hepsia hosting Control Panel. There’re two different features that can be upgraded – the number of instances and the memory. The first one depends on the number of the sites that you’d like to employ Varnish for and the second one, which comes in increments of 32 megabytes, displays the maximum amount of data that the data caching platform can store at any particular time. The Hepsia Control Panel’s easy-to-work-with GUI will permit you to remove or to reboot any instance, to check exhaustive logs or to erase the platform’s cache with just one mouse click. For best results, you can employ a dedicated IP address for the sites that will use the platform. With Varnish, your Internet site will open considerably faster, which means more pleased visitors and prospective customers.
Varnish in Semi-dedicated Servers
Varnish is included as standard with all Linux semi-dedicated hosting plans that we are offering and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The Varnish data caching platform comes with 64 MB of system memory for cached data storing purposes and you can employ it with any site that you host in the semi-dedicated server account. In case you need more than that, you can increase the memory allowance. The memory itself is available in increments of 32 megabytes through the Upgrades section of the Control Panel. The same section will enable you to activate more instances as well, if you want to use the Varnish platform with more Internet sites. The two things can be ordered independently – you can cache the content of a single busy Internet site or run a number of websites with the default memory quota. You can take full advantage of the Varnish platform in case you use a dedicated IP address and you can order one with your semi-dedicated package as well. Hepsia will give you complete control over the caching platform and, with no more than one single click, you will be able to clear the cached data, to view a system log file or to reboot an instance.
Varnish in VPS Servers
You can use Varnish with any of our VPS server packages at no additional charge, as the platform is pre-installed and is available by default. The only prerequisite is that the VPS must come with the Hepsia hosting Control Panel, via which you will be able to set up Varnish for any of your sites with only a few clicks. Each package offers a different amount of system memory for data caching purposes, but you will have at least several hundred MB, which is quite enough even for several resource-demanding websites. Soon after you activate Varnish, it will start caching the content that your site visitors request, so you will notice the much faster web page load speeds and the decreased load on the VPS very soon. The platform will allow you to use a less pricey Virtual Private Server, since you will not need that much power to ensure the correct operation of your sites even if you own larger websites with numerous visitors. Maximum results are accomplished if the Internet sites which use the Varnish platform use also a dedicated IP.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you’ll get the Varnish content caching platform at no extra charge and you’ll exert total control over it via a truly time and effort saving graphical interface – you will be able to start, to disable or to restart an instance, to view an exhaustive system log, to delete the cached data for any Internet site and much, much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you own high-demand Internet sites with a vast number of visitors, you will notice the significantly better website loading speeds and the less load on your dedicated machine. This will become a fact soon after you start using the Varnish platform, as it will need some time to cache the web pages that visitors browse. You can take full advantage of the platform’s capability if the websites that are using it use also a dedicated IP address, but considering the fact that your server includes a couple of IPs by default, you won’t need to pay anything on top of the monthly charge for the machine itself.
