Learn about Varnish, understand more on web accelerators and learn exactly what it is that they can do.
Varnish is a web accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the load speed of any website, at times even by 100%, depending on the content. This tool is occasionally called an HTTP reverse proxy too and is used to decrease the overall server load and to enhance the access speed for the site visitors. Each time a visitor opens a page on a particular Internet site, the browser request is taken care of by the web server and the requested information is delivered as a response. If Varnish is activated, it caches the web pages that the website visitor browses and in case any of them is accessed once again, it’s fetched by Varnish and not by the web server directly. The improvement in the overall performance is due to the fact that the accelerator handles the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is edited meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody accesses them.
Varnish in Shared Hosting
You can take advantage of Varnish’s potential and increase the load speed of your sites regardless of the shared hosting
package that you’ve chosen and you can activate and set up the data caching platform with a couple of clicks of the mouse via the simple-to-use interface offered by our leading-edge Hepsia Control Panel. During the process, you will be able to select two separate things – how many sites will employ the Varnish caching platform, in other words – the number of instances, and how much content will be cached, in other words – the amount of memory. The latter is offered in increments of 32 MB and is not tied to the number of instances, so you can use more instances with less memory and the other way around. If you’ve got lots of content on a certain Internet site and you gain numerous site visitors, more system memory will give you a better result. You may also consider using a dedicated IP address for the Internet sites that will use the Varnish platform. The Hepsia Control Panel will offer you easy one-click buttons for removing or rebooting any instance, for deleting the cache associated with any website and for viewing elaborate logs.
Varnish in Semi-dedicated Servers
Varnish is included by default with all semi-dedicated hosting plans
offered by us and you can use it for workload balancing purposes. It is available in your Hepsia hosting Control Panel. The Varnish data caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can employ it with any website that you host in your semi-dedicated account. In case you are in need of more than that, you can increase the system memory quota. The memory itself is offered in increments of 32 megabytes in the Control Panel’s Upgrades section. The same section will enable you to add more instances too, in case you’d like to use the Varnish platform with more websites. The two upgrades can be added independently – you can cache the content of one traffic-intensive website or use several sites with the default memory allowance. You can take full advantage of the Varnish platform in case you use a dedicated IP and you can order one with your semi-dedicated package as well. The Hepsia Control Panel will give you complete control over the platform and, with no more than one click of the mouse, you will be able to clear the cached data, to see a system log file or to restart an instance.
Varnish in Dedicated Servers
All dedicated web hosting plans
that are ordered with the custom-built Hepsia hosting Control Panel include Varnish, which is one of the pre-installed platforms that you will get with the machine. The Varnish content caching platform can be enabled and administered effortlessly through Hepsia’s time and effort saving interface and, with no more than one mouse click, you can view an in-depth log, create or reboot an instance, clear the cached data associated with any Internet site and much, much more. Shortly after you set up the Varnish platform for a specific domain or sub-domain, it will begin caching the web pages requested by the website visitors and once it has cached enough web content, you will perceive a considerably better website performance and a lowered load on your server. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the platform for load balancing purposes even if you host an immense number of websites on your dedicated machine.
