About this lesson
Everyone says 'Docker is lightweight' and 'VMs are slower' - but can you explain why? VMs run complete operating systems with their own kernel. Containers share the host kernel and just package your app. That's why a virtial machine(VM) needs 2GB while a container needs 50MB. In 5 minutes, you'll finally understand the architecture that makes containers 40x more efficient - and when you'd still choose a VM."
