Varnish is a web accelerator platform, which caches information for the sake of quicker access. It is sometimes called a caching HTTP reverse proxy as well and it works between a web server and its users. When a website visitor loads a certain web page, its content is requested by the Internet browser, and then the web server processes this browser request and delivers the requested information. If Varnish is enabled for a specific site, it will cache the pages at the first request and if the visitor visits a cached page once again, the information will be delivered by the accelerator platform instead of the web server. The improved speed is an end result of the much faster response speed that the Varnish platform offers compared with any web server software. At the same time, this doesn’t mean that the visitors will continue being served the very same content over and over again, because any change on any of the web pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Cloud Web Hosting
Varnish is available as an optional upgrade with all our Linux cloud web hosting service. You can add it to your account via the Hepsia Control Panel, which is available with all shared plans and you’ll get an amazingly simple-to-use graphical interface, which will grant you complete control over the data caching platform. Using one-click quick-access controls, you can restart or terminate any of the instances, i.e. Varnish will no longer work for a specific website. You can also see an elaborate system log or clear the cache for any of the sites. When you add Varnish to your shared web hosting package, you will be able to select the total amount of system memory that will be available to you for content caching purposes and the number of the websites that will use Varnish. You can always add more memory in increments of 32 megabytes and, for maximum performance, you can get a dedicated IP address for the sites that will use Varnish. This will allow you to take full advantage of your Internet sites and to have plenty of pleased visitors.
Varnish in Semi-dedicated Servers
The Varnish content caching platform is an essential part of the standard service set that you’ll get if you choose to host your Internet sites in a semi-dedicated server account. You can activate it for any of your Internet sites through our cutting-edge Hepsia hosting Control Panel. The default memory that Varnish can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this amount 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 caching platform simultaneously. Since these two things are not tied to each other, you can use several websites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for a single website. The Varnish platform works best if you assign a dedicated IP to the websites that utilize its power. The Hepsia Control Panel will give you a simple way of restarting any instance. Also, you’ll be able to delete the cached files with only one single click.
Varnish in VPS Servers
Varnish comes by default with all Linux VPS service that we’re offering on the condition that the VPS server is ordered with the Hepsia Control Panel, so you can enhance the work of your sites with only a few clicks of the mouse. The more powerful the package, the more memory Varnish will have at its disposal, but even with a low-end plan, the caching platform will be able to utilize several hundred MB, so even if you run a handful of Internet sites, you’ll notice an enormous reduction in the server load and a substantially faster page load speed. The platform will need to work for a while while the visitors browse the site and as soon as the content has been cached, you’ll see the result. One of the pluses of using Varnish is that a lower-end and less expensive plan will do the exact same job as a more costly one without the platform, so not only will your websites perform significantly better, but you will also spare some cash.
Varnish in Dedicated Servers
All dedicated servers that are ordered with the in-house built Hepsia hosting Control Panel feature Varnish, which is among the pre-installed software platforms that you will get with the dedicated machine. The Varnish data caching platform can be set up and managed without efforts through Hepsia’s simple-to-use GUI and, with no more than one single click, you can browse a comprehensive log, add or restart an instance, clear the cached files for any Internet site and much, much more. Soon after you set up the Varnish platform for a certain domain or subdomain, it will start caching the web pages browsed by the site visitors and as soon as it has cached enough web content, you’ll perceive a considerably faster site performance plus a reduced 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 run plenty of sites on your machine.
