What is Virtualization?
Virtualization is the process of distributing hardware capabilities across multiple machines. This process is commonly used to give access to operating system specific applications on a single machine, or to free space on a server and reduce operating costs.
By utilizing hypervisor software on your hardware, you can create multiple virtual machines (VM) that a single machine can access to perform multiple functions while using fewer total resources.
This operation has been used by companies and individuals for decades to consolidate their resources and improve efficiency. They give users the ability to access multiple functions and perform various operations through a single machine.
There are multiple types of virtualization:
- Data Virtualization: Consolidates multiple data sources into a single source. Perfect for easily giving access to multiple data sources to people in one location.
- Desktop Virtualization: Allows a single desktop to access many other desktops. Gives an admin the ability to update and configure multiple machines at once.
- Server Virtualization: By partitioning a server, you can allow it to use its components to perform multiple functions where normally it can only perform one.
- Operating System Virtualization: On one machine, you can run multiple operating systems like Windows, MacOS or Linux side-by-side.
- Network Functions Virtualization: This process involves consolidating network functions, like firewalls and directory services, so they can be used across multiple environments without the need for several physical machines.
