Containers Are NOT Magic - How Linux Controls CPU & Memory (cgroups)

Containers are NOT magic, they are powered by Linux internals.

In this short, you’ll learn how Linux controls CPU and memory using cgroups, the core mechanism behind Docker and Kubernetes resource limits.

👉 Key concepts covered:

- How Linux controls groups of processes (not individual ones)
- Why all processes inside a container share the same limits
- The real reason containers are reliable
- Difference between cgroups v1 vs cgroups v2
- Why modern systems prefer cgroups v2 unified hierarchy

If you're learning DevOps, Kubernetes, or Docker internals, this is one of the most important concepts to understand.

💡 Containers = Namespaces (isolation) + cgroups (resource control)
