Learn about Varnish, understand more about web accelerators and see exactly what is they do.
Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, as it can increase the loading speed of any site, at times even by one hundred percent, depending on the content. This tool is sometimes called a caching HTTP reverse proxy too and is used to reduce the overall load on the physical server and to increase the browsing speed for the website visitors. Anytime a visitor loads a page on a certain Internet site, the web browser request is handled by the web server and the requested data is sent as a response. If the Varnish accelerator is activated, it caches the pages that the visitor browses and in case any of them is loaded for a second time, it is fetched by Varnish and not by the web server directly. The improvement in the performance is due to the fact that the accelerator handles the web requests considerably quicker than any web server, which results in much faster browsing speeds for the users. If any content is updated in the meantime, the cached web pages will also be updated the next time somebody attempts to open them.
Varnish in Cloud Website Hosting
You can unlock Varnish’s potential and optimize the loading speed of your sites irrespective of the cloud website hosting
package that you have chosen and you can activate and set up the content caching platform with a few clicks from the simple-to-use graphical interface offered by our cutting-edge Hepsia Control Panel. During the process, you will be able to select two separate things – how many websites will employ the Varnish caching platform, in other words – the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter is available in increments of 32 MB and is not bound to the number of instances, so you can order more instances with less memory and vice versa. If you have plenty of content on a given site and you receive many site visitors, more memory will give you a better result. You may also consider employing a dedicated IP address for the websites that will use Varnish. The Hepsia Control Panel will offer you simple 1-click buttons for discontinuing or restarting any instance, for erasing the cache associated with any website and for viewing detailed system logs.
Varnish in Semi-dedicated Hosting
Varnish is an essential part of the default set of services that you’ll get when you choose to host your sites in a semi-dedicated server
account. You can enable it for any of your sites through our next-gen Hepsia Control Panel. The default system memory that Varnish can use to cache data is 64 MB, but if you decide that you need more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform simultaneously. Since these two things aren’t tied to each other, you can use a few websites with the default memory or you can add more memory in increments of 32 MB and use all of it for a single Internet site. Varnish works best if you use a dedicated IP for the Internet sites that utilize its power. The Hepsia Control Panel will provide you with an easy means of rebooting any instance. On top of that, you will be able to clear the cached contents with only one click.
Varnish in Dedicated Web Hosting
All Linux dedicated servers hosting packages
which are ordered with the custom-developed Hepsia website hosting Control Panel come with Varnish, which is among the pre-installed platforms that you will get with the server. The Varnish caching platform can be enabled and managed with ease from the Hepsia Control Panel’s simple-to-use GUI and, with no more than one mouse click, you can browse an exhaustive system log, add or restart an instance, clear the cached data for any website and much, much more. Shortly after you configure Varnish for a specific domain or sub-domain, it will start caching the web pages loaded by the website visitors and as soon as it has cached enough web content, you will witness a substantially faster site performance plus a reduced load on your server. With Varnish-dedicated memory starting at 3 gigabytes, you’ll be able to use the software platform for load distribution purposes even if you run numerous websites on the dedicated server.
