Varnish is a data caching platform, which is sometimes called a caching HTTP reverse proxy. It is a website accelerator that can accelerate the loading speed of a website by up to 1000 percent, based on the content itself. Anytime a visitor opens any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor opens it again. Thus, the web browser request from the visitor is not processed by the web server and the page will load much faster, since the Varnish caching platform can serve information many times faster than any server software. The end result will be a considerably faster loading page, which leads to an enormously improved visitor experience. When any of the cached webpages is updated on the live website, the information that Varnish saves in its system memory is updated as well, so the visitors won’t end up seeing old information.
Varnish in Shared Hosting
You can take advantage of Varnish’s potential and enhance your websites’ loading speed regardless of the shared hosting package that you’ve chosen and you can enable and configure the content caching platform with a few mouse clicks via the simple-to-use graphical interface offered by our leading-edge Hepsia hosting Control Panel. During the process, you’ll be able to select two different things – how many Internet sites will use the Varnish caching 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 offered in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances with less memory and vice versa. If you have a lot of content on a particular Internet site and you receive lots of site visitors, more system memory will give you better results. You may also consider using a dedicated IP address for the websites that will use the Varnish platform. Hepsia will provide you with easy 1-click buttons for removing or restarting any instance, for erasing the cache for any Internet site and for checking exhaustive logs.
Varnish in Semi-dedicated Hosting
The Varnish content caching platform is part of the standard set of services that you’ll get in case you decide to host your websites in a semi-dedicated server account. You can configure it for any of your websites via our innovative Hepsia hosting Control Panel. The default system memory that the Varnish caching platform can use to cache content is 64 megabytes, but in case you decide that you want more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. Since these two features aren’t linked to each other, you can use a couple of instances with the default amount of memory or you can order more memory in increments of 32 megabytes and use all of it for one single site. Varnish performs best if you allocate a dedicated IP to the websites that utilize its power. Hepsia will give you a simple means of rebooting any instance. Furthermore, you’ll be able to clear the cached data with only one mouse click.
Varnish in Dedicated Hosting
All Linux dedicated servers hosting packages that are ordered with the tailor-made Hepsia web hosting Control Panel come with Varnish, which is one of the pre-installed software platforms that you’ll get with the dedicated machine. The Varnish platform can be enabled and managed effortlessly through the Hepsia Control Panel’s simple-to-use GUI and, with no more than one single click, you can check an in-depth system log, create or restart an instance, clear the cached files for any site and much more. Soon after you configure Varnish for a certain domain or sub-domain, it will begin caching the pages browsed by the site visitors and as soon as it has cached enough web content, you’ll witness a substantially faster website performance and a reduced server load. With Varnish-dedicated virtual memory starting at 3 gigabytes, you’ll be able to use the software platform for load balancing purposes even if you run many Internet sites on your dedicated machine.
