There are numerous open source Linux virtualization platforms based on KVM, while Microsoft has Hyper-V with Windows cloud servers, Citrix maintains the Xen server framework, and VMware has a number of different hypervisor frameworks such as ESXi. Hypervisors permit the managing of multiple web servers independently on shared hardware each with isolated databases, file storage, and I/O request processing.
If you are just starting your website and don’t receive very much traffic, then shared hosting is the ideal solution. However, if your website’s audience is consistently growing, you’ll want to consider upgrading. You don’t want to run the risk of your website running slowly or, even worse, your server crashing because it can’t handle the traffic. If you anticipate an increase in visitors, do yourself a favor and switch to VPS.
The hypervisor provides each guest machine (each website using the VPS) with a virtual operating system and takes care of managing and executing guest operating systems. This process makes the most effective use of computer resources such as network bandwidth, memory space and processor cycles. For this reason, a hypervisor also goes by the name of a virtual machine monitor (VMM).
You can also create "Sub-servers" and "Alias" servers. Alias servers are useful if for example you have both a ".com" and a ".co.uk" domain - website visitors and mail users can use either domain and will see the same website or reach the same mailbox. Sub-servers are useful if one administrator is managing several different sites - if they all have the same owner then there's no need to log in and out to move between them.
You’re paying more, so there SHOULD be a minimum uptime guarantee and better server speed. Look for a host that offers 99.5% at a very minimum, although ideally, I’d rather go with someone who offers 99.9%. Search through some reviews as there are many who have put this to the test. For example, any of WHSR’s many web host reviews include an uptime record as one of our key tests.
VPS installation on SSD storage is much faster than HDD, where managed platforms offer a pre-installed partition available instantly after sign-up for a new hosting account and some "bare metal" partitions take longer to create. Unmanaged plans usually require the customer to install the operating system and web server stack software on a VPS plan personally. Cloud VPS plans offer snapshot services like Bitnami that can speed up web server installation and CMS application deployment considerably. Beginners will prefer managed VPS plans with CentOS and cPanel for a near identical user experience for multi-domain management as on shared Linux hosting plans.
VPS hosting is a great option for anyone who has outgrown the basic features of a shared plan. It’s perfect for small businesses that are steadily growing and gaining more traffic. You get more resources to support that growth and better control over how your site performs. Plus, you can easily adapt the hosting service to meet your needs as they change.

To connect to the Virtualmin web interface and complete the installation, point your browser to port 10000, using https for a secure connection. For example, if the IP address of your server is 192.0.2.0, the address to visit would be https://192.0.2.0:10000. You will get a warning about an untrusted certificate, which you can ignore for now. Login with same administrator username and password you used above.
