VMs vs Docker

9. ‧Portability — Software packaged in containers
can be moved and deployed more easily than a
full Virtual Machine image
‧Startup speed — VMs need to boot the guest
OS before they can do anything else. Containers
start running your software almost instantly
‧Flexible composition — Containers are best
used when each process in your stack runs in its
own container, making it easier to compose
flexible and robust platforms instead of
monolithic servers
