Dedicated server is a type of server which can be remotely operated that’s is entirely dedicated to an individual or an organization. This type of server is totally personal and hence not shared with any other customer or services.
VM server are those which provides fully equipped and functional virtual environment through virtualization technology. Usually it consists of two modes; paravirtual mode followed by full virtual mode, where paravirtual mode are designed to execute computer programs in a platform independent environment and full virtual mode are designed to provide a substitute for a real machine.
When you say about dedicated server, they are actually a physical machine whereas when you talk about VM servers they aren’t physical machines they are actually a software package
When you have dedicated server you actually own everything whereas when you say about VM server you actually have a part of the server which you will have access to use.
Usually virtual servers run on dedicated server, wherein the resources of that are divided between many virtual servers. Also, the dedicated server runs a software package.
Virtualization can, in limited cases, cause resource contention issues that impact performance. Dedicated servers don’t suffer from this particular problem.
Dedicated server means single tenant environment: only one client has access to the hardware whereas VM servers consists of multi-tenants environment: a client has sole access to the virtual server environment, but the hardware is shared with two or more clients.
Virtual servers are typically more scalable, flexible, and agile over a short period of time. Looking upon the dedicated servers the major benefits about them is power and performance. The dedicated servers are also known as Bare Metal servers.
