What is a hypervisor?

• Software to manage virtualized resources on a physical implementation.

• Software to log and monitor operations

• Hardware to connect networking and compute modules

• Hardware to provide to connect storage and compute modules

Which one represents Infrastructure as a Service (IaaS)?

• Infrastructure that allow developers to run their code.

• Services are provided without infrastructure or service maintenance concerns.

• You get control over underlying compute and storage resources

• Infrastructure complexity is automated and hidden via an API

Which one represents Platform as a Service (PaaS)?

• You get control over underlying compute and storage resources

• Services are provided without infrastructure or service maintenance concerns

• Infrastructure complexity is automated and hidden via an API or the push of a button.

• Infrastructure that allow developers to run their code.
