" summary

Compares containers and virtual machines with concrete numbers and tools: containers start in seconds and share the host kernel while VMs require a hypervisor and VM boot ~30s and full OS installs; image build often takes minutes but containers run in ~1–2 seconds. Shows a Python app packaged into a Docker image, uses port mapping to expose services, contrasts resource overhead (containers lean, VMs reserve RAM/CPU) and confirms containers remain isolated and resilient when one crashes.
