Varnish is a web application accelerator platform, which caches content for the sake of quicker access. It’s occasionally called an HTTP reverse proxy as well and it works between a web server and a browser. When a site visitor loads a certain web page, the content is requested by the Internet browser, and then the web server processes this browser request and returns the needed data. If Varnish is enabled for a certain website, it will cache its pages at the very first request and if the visitor accesses a cached page once more, the content will be delivered by the caching platform and not by the web server. The accelerated speed is a result of the substantially faster response speed that Varnish offers compared with any web server software. Of course, this doesn’t mean that the site visitors will continue seeing the very same content over and over again, as any change on any of the pages is reflected in the content that Varnish saves in its memory.
Varnish in Shared Website Hosting
In case you host your Internet sites under a shared website hosting
account with us, you will be able to add Varnish with a few clicks through your Control Panel. The platform is available as an optional upgrade with all our web hosting plans and you can select how many sites will use it and the maximum amount of system memory that will be used for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t tied directly to each other, so you can decide if you want lots of memory for one single large-scale website or less memory for multiple smaller ones. You can use the full potential of the Varnish platform in case the sites use a dedicated IP address. Using the hosting Control Panel, you can swiftly start/reboot/deactivate an instance, clear the cached content independently for each site which uses Varnish or check an exhaustive system log file.
Varnish in Semi-dedicated Hosting
The Varnish caching platform is an essential part of the default set of services that you’ll obtain if you choose to host your websites in a semi-dedicated server
account. You can set it up for any of your websites via our cutting-edge Hepsia Control Panel. The default memory that the Varnish caching platform can use to cache content is 64 megabytes, but if 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 Internet sites that can use this caching platform simultaneously. As these two features aren’t tied to each other, you can use a couple of websites with the default memory or you can add more memory in increments of 32 MB and use all of it for a single website. The Varnish caching platform performs best if you set a dedicated IP address for the Internet sites that utilize its power. Hepsia will provide you with a simple way of rebooting any instance. In addition, you’ll be able to delete the cached data with only one click of the mouse.
Varnish in VPS Hosting
We offer Varnish with all Hepsia-equipped Linux VPS hosting
, so in case you acquire a server with this hosting Control Panel, you will be able to take full advantage of the content caching platform at no additional charge. The Varnish platform can use different amounts of system memory for content caching purposes based on the particular setup that you have selected at signup, but in any case, this amount won’t be less than several hundred MB. This is quite enough to enhance the work of several different traffic-consuming Internet sites, so the better website loading speeds and the reduced load on the virtual machine will be perceivable. The result may not be evident instantly, since Varnish will require a certain amount of time to cache the website content that people request, but soon after you activate it, you’ll perceive its full potential. This caching platform will permit you to use a less powerful Virtual Private Server and to give less money to get the exact same performance you’d get with a more powerful machine without Varnish.
Varnish in Dedicated Web Hosting
All Linux dedicated hosting services
that are ordered with the tailor-made Hepsia hosting Control Panel come with Varnish, which is one of the pre-installed software platforms that you will get with the dedicated machine. The Varnish caching platform can be configured and administered with ease via the Hepsia Control Panel’s easy-to-work-with interface and, with no more than one single click, you can check an exhaustive log, create or restart an instance, clear the cache for any website and much, much more. Soon after you enable Varnish for a specific domain or subdomain, it will start caching the webpages loaded by your site visitors and once it has cached enough web content, you will observe a considerably faster site performance as well as a reduced load on your dedicated machine. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the software platform for workload balancing purposes even if you run an enormous number of websites on the dedicated server.
