What are the types of hypervisor?
There are two main hypervisor types, referred to as “Type 1” (or “bare metal”) and “Type 2” (or “hosted”). A type 1 hypervisor acts like a lightweight operating system and runs directly on the host’s hardware, while a type 2 hypervisor runs as a software layer on an operating system, like other computer programs.
What is abstraction in cloud computing and discuss its types?
Abstraction enables the key benefit of cloud computing, which is shared, ubiquitous access. Abstraction is the act of representing essential features while hiding the background details from users and developers. It is used to reduce cost and complexity, which in turn, simplifies operations.
Who controls the cloud?
