Learn about Varnish, understand more about web accelerators and learn just what it is they do.
Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, because it can increase the loading speed of any Internet site, sometimes even by one hundred percent, based on the content. This tool is occasionally called a caching HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to improve the browsing speed for the website visitors. Anytime a visitor loads a page on a particular site, the browser request is handled by the web server and the requested info is served as a response. If Varnish is enabled, it caches the web pages that the visitor browses and in case any of them is accessed again, it’s delivered by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator processes the browser requests considerably quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is modified in the meantime, the cached pages will also be ‘refreshed’ the next time somebody opens them.
Varnish in Cloud Website Hosting
You can unleash Varnish’s full potential and boost your sites’ load speed regardless of the cloud website hosting
plan that you’ve picked and you can enable and set up the content caching platform with several mouse clicks through the intuitive GUI offered by our leading-edge Hepsia hosting Control Panel. During the procedure, you will be able to choose two different things – how many Internet sites will employ the Varnish platform, i.e. the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can use more instances and less memory and vice versa. If you have a lot of content on a specific website and you get a lot of site visitors, more system memory will give you a better result. You may also consider using a dedicated IP address for the websites that will use the Varnish platform. The Hepsia Control Panel will provide you with easy 1-click controls for removing or rebooting any instance, for erasing the cache for each Internet site and for viewing in-depth system logs.
Varnish in Semi-dedicated Servers
The Varnish content caching platform is an essential part of the default set of services that you will receive if you decide to host your websites in a semi-dedicated server
account. You can set it up for any of your sites through our leading-edge Hepsia hosting Control Panel. The default amount of 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 memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform at the same time. As these two features aren’t bound to each other, you can use several Internet sites with the default memory or you can order more memory in increments of 32 MB and use all of it for a single website. Varnish performs best when you allocate a dedicated IP to the Internet sites that utilize its power. Hepsia will offer you a simple means of rebooting any instance. Furthermore, you will be able to clear the cached files with just one click of the mouse.
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 virtual machine is ordered with the Hepsia Control Panel, so you can enhance the performance of your sites with only a few clicks. The more powerful the plan, the more memory will be available to Varnish, but even with a lower-end package, the platform will be able to utilize several hundred megabytes, so even if you’ve got a number of websites, you’ll notice a serious decrease in the overall server load and a tremendously faster site loading speed. The Varnish caching platform will have to work for a while while the visitors navigate the website and as soon as the website content has been cached, you will distinguish the results. One of the upsides of employing Varnish is that a less powerful and less expensive Virtual Private Server package will accomplish the exact same job as a more pricey one without the caching platform, so not only will your websites work significantly better, but you will also save some cash.
Varnish in Dedicated Servers
In case you order a dedicated server
with the Hepsia hosting Control Panel, you will acquire the Varnish content caching platform at no extra charge and you will exert complete control over it through a rather easy-to-use interface – you will be able to start, to remove or to reboot an instance, to view an elaborate system log, to clear the cached files for any Internet site and much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you’ve got resource-intensive sites with plenty of visitors, you will notice the tremendously faster page loading speeds and the reduced load. This will become a fact shortly after you begin using Varnish, since it will require a certain amount of time to cache the web pages that people access. You can get the most out of the platform’s potential in case the sites that are using it use also a dedicated IP address, but since your server comes with a couple of IPs by default, you won’t have to pay anything on top of your monthly charge for the server itself.
