Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, because it can increase the loading speed of any Internet site, at times even by 100 percent, based on the content. This tool is sometimes called an HTTP reverse proxy too and is used to reduce the overall server load and to improve the browsing speed for the website visitors. Whenever a visitor loads a page on a certain website, the browser request is processed by the web server and the requested data is delivered as a response. If the Varnish accelerator is enabled, 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 performance is due to the fact that the accelerator processes the web requests tremendously quicker than any web server, which results in much faster browsing speeds for the website visitors. If any data is modified in the meantime, the cached web pages will also be updated the next time someone opens them.
Varnish in Shared Web Hosting
If you host your websites under a shared web hosting account with our company, you will be able to activate Varnish with a few clicks via your Control Panel. The content caching platform comes as an optional upgrade with all our packages and you can select how many websites will use it and the maximum storage space that will be used for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they are not tied directly to each other, so you can decide if you need plenty of memory for one single large site or less memory for several smaller ones. You can make use of the full potential of the Varnish platform if the websites use a dedicated IP. With the hosting Control Panel, you can quickly start/restart/shut down an instance, clear the cached files independently for each site that uses the Varnish platform or check a detailed log.
Varnish in Dedicated Hosting
All Linux dedicated servers hosting packages which are ordered with the tailor-made Hepsia web hosting Control Panel feature Varnish, which is among the pre-installed platforms that you will get with the dedicated machine. The Varnish platform can be configured and managed without any effort from the Hepsia Control Panel’s user-friendly interface and, with no more than a click, you can see an elaborate log, create or restart an instance, delete the cached content associated with any Internet site and much, much more. Soon after you activate the Varnish platform for a certain domain or subdomain, it will begin caching the pages browsed by the visitors and once it has cached enough content, you will observe a substantially better site performance as well as a lowered load on the dedicated machine. With Varnish-dedicated virtual memory starting at 3 gigabytes, you will be able to use the platform for load balancing purposes even if you host plenty of websites on your server.
