Containers virtualize at the OS level and share kernels for lightweight workload execution, while VMs virtualize full hardware stacks, increasing overhead and reducing deployment speed.

Registries store versioned container artifacts, enabling pipelines to promote containers across environments, control release versions, and enforce compliance policies for deployment governance.

Risks include image vulnerabilities, privilege escalation, secrets exposure, and insecure network paths; enterprises mitigate using scanning tools, RBAC, namespaces, and network policies.

Docker provides workload packaging while Kubernetes/ECS handle scheduling, scaling, and resilience, forming the foundation of cloud-native application delivery.

Developers, DevOps engineers, SREs, platform engineers, and QA professionals involved in distributed application delivery.

Not mandatory, but most production environments use Kubernetes to orchestrate containers at scale, making Kubernetes familiarity beneficial.
