Technical knowledge: No technical knowledge is required for running a managed server. When you need to do something technical all you have to do is contact support and let the skilled technical support operators handle the rest. With an unmanaged server you need to have server administration skills and love working in the command line otherwise it will be very difficult to administer your server efficiently.
A key aspect of VPS internet hosting is its virtualization capabilities. With VPS, the hosting provider divides each physical server into multiple smaller virtual servers with private and dedicated RAM and hard drive space. This provides site owners with a more isolated hosting environment without disruptions from other clients sharing server space.
There is a good chance that your company or the clients you are hosting will want to create their own custom nameservers for their properties, opting to use ns.yourdomainhere.com over a host-specific nameserver. Updating nameservers for domains is very simple within our Account Management Panel (AMP). If your domain is currently with another host/registrar, you also have the option of pointing the nameservers to ns1.inmotionhosting.com without transferring the domain to InMotion Hosting. Creating custom nameservers requires root access, which is available by request for all VPS Hosting plans.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.
