Virtualization and Containers

What this page covers

The resources fall into two broad groups: hypervisor-based virtualization and containers. On the VMware side, the quizzes follow the VCP route. Titles such as Vmware VCP, VCP-DCV and Professional VMware vSphere 7.x (2V0-21.20) sit alongside questions on ESXi installation, distributed switches, Flash Read Cache and Auto Deploy. Other quizzes ask what virtualization is for, and how a virtual machine differs from a container.

Containers and orchestration

The Kubernetes Mind Map explains containers through cgroups, namespaces and union filesystems. The kubectl Mind Map lists commands, including creating a deployment from an nginx image with a dry run. The docker Mind Map covers advantages such as portability, density and lower licensing cost. Flashcard decks go further, with sets on Docker commands, images, compose and registry, and on Kubernetes concepts, pods and deployments. The CKA exam is mentioned among the listed resources.

Where to start

1. Open one of the many Virtualization mind maps for the basic ideas.
2. Work through the Virtualization Midterm flashcards to learn the vocabulary.
3. Take the vSphere 6 Foundations Quiz or the Kubernetes quiz.
4. Move on to the VCP question sets and the 2V0-21.20 quiz.

Using quizzes and maps together

Take a quiz first and note the questions you miss. Then open the map that matches the topic, such as the docker or VMware maps, and read the branch that covers the gap. Try the quiz again afterwards. Hands-on notes, such as the virsh exercises on NAT networks and storage pools, give you commands to practise.

Where it sits

This unit belongs to the Networks, the Internet and Cloud strand of Computing and ICT. It links naturally to the networking and cloud material around it. Teachers can pick a quiz or map for a class, and everyone can choose a resource and begin.
