This diagram shows two ways to run multiple isolated environments on one physical server.

Virtualization: The physical server runs a hypervisor layer. This hypervisor creates multiple virtual machines (VMs). Each VM has its own full operating system (OS). This means each VM is like a separate computer inside the server.

Containers: Instead of full VMs, containers share the same host OS. The container engine runs on top of the host OS and manages multiple containers. Each container is isolated but shares the OS kernel, making containers lighter and faster to start than VMs.

In summary, virtualization uses separate OS instances for each VM, while containers share one OS but keep applications isolated.

Variations - 2 Challenges

[intermediate] Draw a flowchart that explains the steps to start a virtual machine versus starting a container on a server.

[advanced] Draw a detailed diagram showing how resources like CPU and memory are allocated differently in virtualization and containerization on a physical server.
