What is VPS?

What is VPS? Virtual private server (VPS)

A VPS is a virtual machine running in software on the same physical computer as other customers’ virtual machines and is functionally equivalent to a separate physical computer.

Virtual private servers bridge the gap between “shared web hosting” services and “dedicated hosting” services, giving independence from other customers of the VPS service in software terms but at less cost than a physical dedicated server.

What is Cloud server?

A VPS, which is dynamic, (that is, it can be changed at runtime) is often referred to as a cloud server. Key attributes for this are:

– Additional hardware resources can be added at runtime (CPU, RAM) – Server can be moved to other hardware while the server is running (automatically according to load in some cases)
