Learn just what Varnish is. Get to know more about web accelerators and their function.
Varnish is a web accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any Internet site, sometimes even by 100%, based on the content. This tool is occasionally called a caching HTTP reverse proxy as well and is used to reduce the overall server load and to enhance the access speed for the site visitors. Every time a visitor loads a page on a given website, the web browser request is handled by the web server and the requested data is served as a response. If Varnish is activated, it caches the pages that the website visitor browses and if any of them is loaded once more, it is delivered 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 web requests considerably quicker than any web server, which results in much faster browsing speeds for the users. In case any content is edited meanwhile, the cached webpages will also be ‘refreshed’ the next time somebody tries to access them.
Varnish in Shared Website Hosting
You can take advantage of Varnish’s full potential and accelerate the speed of your sites irrespective of the shared website hosting
plan that you have chosen and you can enable and configure the platform with a few clicks via the simple-to-use GUI offered by our cutting-edge Hepsia hosting Control Panel. During the process, you will be able to select two different things – how many Internet sites will employ the Varnish caching platform, i.e. the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances with less memory and the other way around. In case you’ve got a lot of content on a given Internet site and you get lots of website visitors, more system memory will guarantee you better results. You may also consider employing a dedicated IP for the sites that will use the Varnish platform. Hepsia will provide you with easy 1-click buttons for shutting down or rebooting any instance, for erasing the cache associated with any website and for checking exhaustive logs.
Varnish in Semi-dedicated Servers
Varnish is a feature, which comes by default with all Linux semi-dedicated servers
offered by us and you can use it for workload balancing purposes. It’s available in your Hepsia Control Panel. The data caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any Internet site that you host in your semi-dedicated server account. In case you’re in need of more than that, you can increase the system memory allocation. The memory itself is offered in increments of 32 MB in the Upgrades section of the Control Panel. The same section will permit you to enable more instances as well, in case you would like to use Varnish with more websites. The two things can be ordered separately – you can cache the content of a single traffic-heavy site or use several websites with the default memory. You can get the most out of the Varnish platform in case you use a dedicated IP and you can order one with your semi-dedicated plan as well. The Hepsia Control Panel will give you total control over the platform and, with no more than one mouse click, you’ll be able to clear the cached data, to see a system log file or to reboot an instance.
Varnish in VPS Servers
You can take advantage of Varnish with any of our VPS server
plans at no additional fee, since the data caching platform is pre-installed and is offered by default. The sole condition is that the VPS must be ordered with the Hepsia Control Panel, via which you’ll be able to set up Varnish for any of your websites with just a couple of clicks. Each package includes a different amount of system memory for content caching purposes, but you will have minimum several hundred MB, which is quite sufficient even for multiple resource-absorbing sites. Soon after you enable the Varnish platform, it will begin caching the content that your visitors request, so you will notice the significantly better website loading speeds and the less load on the VPS in no time. The caching platform will permit you to use a less costly VPS server, as you won’t require that much power to sustain the uninterrupted operation of your sites even if you manage traffic-intensive sites with many visitors. Optimal results are accomplished if the websites which use the Varnish caching platform use also a dedicated IP address.
Varnish in Dedicated Servers
All dedicated web hosting plans
which are ordered with the custom Hepsia web hosting Control Panel feature Varnish, which is among the pre-installed platforms that you will get with the dedicated server. The Varnish caching platform can be activated and managed with ease through Hepsia’s intuitive graphical interface and, with no more than one single click, you can browse an in-depth system log, create or reboot an instance, delete the cached content for any Internet site and much more. Soon after you configure the Varnish platform for a specific domain or subdomain, it will begin caching the web pages requested by the visitors and as soon as it has cached enough content, you’ll perceive a tremendously better website performance and a reduced load. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the software platform for load distribution purposes even if you host an enormous number of websites on the dedicated server.
