Virtualization

Virtualization is the process of creating a virtual version of something, such as an operating system or a server. It allows multiple operating systems, applications, and resources to run on a single physical machine, resulting in greater efficiency and flexibility.

Hypervisor

A hypervisor, also known as a virtual machine monitor, is the software that creates and manages virtual machines. It allows multiple operating systems to run on a single physical machine by providing each operating system with its own virtual hardware resources.

Virtual Machine

A virtual machine (VM) is a software emulation of a physical machine. It runs an operating system and applications just like a physical machine, but it shares the physical resources of the host machine with other virtual machines.

Host Machine

The host machine is the physical machine that runs the hypervisor and hosts one or more virtual machines.

Guest Machine

A guest machine is a virtual machine that runs on a host machine.

Virtualization Layer

The virtualization layer is the software layer that sits between the physical hardware and the virtual machines. It manages the allocation of physical resources to virtual machines and provides a virtualized view of those resources to the guest operating systems.

Containerization

Containerization is a type of virtualization that allows multiple applications to run on a single operating system without the need for a separate virtual machine for each application. It provides a lightweight and efficient way to package and deploy applications.

Conclusion

Virtualization has revolutionized the way we use computing resources. It allows us to maximize the use of physical resources, reduce costs, and increase flexibility. As a product manager, understanding virtualization and its related technologies is essential for developing products that can take advantage of these benefits.
