Varnish is a content caching platform, which is occasionally called a caching HTTP reverse proxy. It is a web application accelerator tool that can accelerate the speed of a site by up to 1000 percent, depending on the content itself. Every time a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor loads it again. Thus, the web browser request from the visitor is not handled by the server and the web page will open significantly faster, since the Varnish platform can serve content many times faster than any server software. The result is a much faster loading page, which leads to a greatly improved browsing experience. When any of the cached pages is updated on the live Internet site, the data that Varnish keeps in its system memory is updated too, so the website visitors won’t see out-of-date content.
Varnish in Web Hosting
In case you host your websites in a web hosting account with us, you’ll be able to activate Varnish with a couple of clicks of the mouse through your hosting Control Panel. The content caching platform comes as an upgrade with all our plans and you can choose the number of the sites that will use it and the total amount of system memory that will be used for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they’re not linked directly to each other, so you can decide if you need a lot of memory for one single large-size website or less memory for several smaller ones. You can use the full potential of the Varnish platform if the sites use a dedicated IP. Using the Control Panel, you can easily start/restart/disable an instance, delete the cached contents independently for each site that employs the Varnish platform or see a detailed log file.
Varnish in Semi-dedicated Servers
The Varnish caching platform is included in the default service set that you’ll receive when you choose to host your sites in a semi-dedicated server account. You can set it up for any of your websites via our next-generation Hepsia hosting Control Panel. The default memory that the Varnish caching platform can use to cache content 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, in other words – the number of the websites that can use this caching platform simultaneously. As these two features aren’t tied to each other, you can use a few instances 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 web site. The Varnish platform performs best if you allocate a dedicated IP to the Internet sites that utilize its power. The Hepsia Control Panel will offer you an easy means of rebooting any instance. On top of that, you will be able to delete the cached content with just one click of the mouse.
Varnish in VPS Servers
You can take advantage of Varnish with any of our VPS server packages at no extra charge, as the caching platform is pre-installed and is included by default. The one and only requirement is that the VPS server must be ordered with the Hepsia hosting Control Panel, via which you will be able to set up Varnish for any of your websites with just a few clicks of the mouse. Each package offers a different amount of system memory for content caching purposes, but you will get no less than several hundred megabytes, which is enough even for multiple frequently visited sites. Shortly after you set up Varnish, it will begin caching the content that your website visitors access, so you will notice the considerably better web page load speeds and the lowered load on your virtual machine in no time. Varnish will permit you to use a less costly virtual machine, since you will not need that many resources to warrant the correct operation of your sites even if you have resource-requiring sites with plenty of visitors. Maximum results are accomplished if the Internet sites which use Varnish use also a dedicated IP address.
Varnish in Dedicated Servers
If you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish caching platform at no additional charge and you’ll exert full control over it through a rather easy-to-use GUI – you will be able to start, to cancel or to restart an instance, to browse an elaborate log, to clear the cache for any website and much, much more. The Varnish platform will have several GB of system memory at its disposal, so even if you run resource-intensive sites with a large number of visitors, you will notice the significantly better web page load speeds and the less load on your dedicated server. This will happen shortly after you start using Varnish, since it will require a certain amount of time to cache the pages that people browse. You can get the most out of the platform’s capacity in case the sites that are using it use also a dedicated IP address, but owing to the fact that your dedicated server comes with a few IP addresses by default, you will not need to pay anything on top of the monthly charge for the machine itself.
