Exploration should include, but not be limited to

• what a virtual machine is and how it can be used as a sandbox
• how virtual machines relate to one another
• the key properties of virtual machines
• isolation
• encapsulation
• hardware independence
• the advantages and disadvantages of virtualization technology.

Virtualization falls into the following categories:

• Container―virtualizing the OS (e.g., Docker, Kubernetes)
• Hypervisor―virtualizing the entire system, including OS (e.g., Hyper-V, VMware, VirtualBox)
• Hyperscaler―allowing rapid and massive scale of virtualization (e.g., data center, cloud computing)
