Varnish is a content caching platform, which is sometimes referred to as a caching HTTP reverse proxy. It’s a web app accelerator tool that can increase the speed of a website by up to one thousand percent, based on the content itself. Each time a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor opens it again. Thus, the web browser request from the visitor is not handled by the server and the web page will open much faster, since the Varnish platform can serve content many times faster than any web server software. The end result is a considerably faster loading website, which leads to an enormously improved visitor experience. When any of the cached webpages is updated on the live Internet site, the data that Varnish keeps in its memory is updated as well, so the website visitors will not see outdated information.
Varnish in Shared Website Hosting
Varnish is available as an optional upgrade with each of our Linux shared website hosting service
. You can add it to your website hosting account via the Hepsia Control Panel, which is offered with all shared web hosting plans and you’ll get an amazingly simple-to-work-with interface, which will grant you complete control over the caching system. Using 1-click quick-access buttons, you can restart or stop any of the instances, i.e. Varnish will no longer be activated for a certain website. You can also check a comprehensive system log file or clear the cache associated with any of the Internet sites. When you add Varnish to your shared hosting package, you will be able to choose the maximum 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 order more memory in increments of 32 MB and, for maximum performance, you can assign a dedicated IP address to the websites that will use Varnish. This will enable you to take full advantage of your sites and to have many pleased visitors.
Varnish in Semi-dedicated Servers
Varnish is offered as standard with all semi-dedicated servers
offered by us and you can use it for workload distribution purposes. It is available in your Hepsia hosting Control Panel. The Varnish caching platform comes with 64 MB of system memory for cached content storing purposes and you can use it with any Internet site that you host in the account. In case you need more than that, you can increase the system memory allocation. The memory itself is available in increments of 32 megabytes through the Upgrades section of the Control Panel. The very same Upgrades section will allow you to add more instances as well, in case you wish to use the Varnish caching platform with multiple Internet sites. The two things can be added independently – you can cache the content of one single traffic-hungry Internet site or use several different websites with the default memory allocation. You can get the most out of the Varnish caching platform in case you use a dedicated IP and you can order one with your semi-dedicated server package as well. The Hepsia Control Panel will give you total control over the platform and, with no more than one click of the mouse, you’ll be able to delete the cached data, to see a system log or to restart an instance.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-managed VPS servers
, so if you obtain a server with this hosting Control Panel, you will be able to take full advantage of the content caching platform at no additional fee. Varnish can utilize different amounts of memory for data caching purposes depending on the very configuration that you’ve chosen during the registration process, but in any case, this amount will not be less than several hundred MB. This is more than enough to improve the overall performance of a handful of large Internet sites, so the better page loading speeds and the reduced load on your Virtual Private Server will be noticeable. The result may not be evident momentarily, as the Varnish platform will require some time to cache the website content that people access, but shortly after you enable it, you will witness its full capacity. This platform will permit you to use a lower-end server and to give less money to get the same performance you’d get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Servers
All Linux dedicated service
that are ordered with the in-house built Hepsia website hosting Control Panel feature Varnish, which is one of the pre-installed software platforms that you will get with the server. The Varnish platform can be enabled and managed without efforts through Hepsia’s easy-to-use graphical interface and, with no more than one click, you can check an exhaustive log, create or reboot an instance, clear the cache for any site and much, much more. Shortly after you enable the Varnish platform for a particular domain or sub-domain, it will start caching the web pages loaded by your visitors and once it has cached enough content, you’ll perceive a substantially faster site performance as well as a decreased load on your server. With Varnish-dedicated virtual memory starting at 3 gigabytes, you will be able to use the software platform for load balancing purposes even if you run a large number of websites on your dedicated server.
