Containers are code execution environments that run within an operating system(for now), sharing and leveraging resources of that operating system. While a VM is a full abstraction of an operating system, a container is a constrained place to run segregated processes while still utilizing the kernel and other capabilities of the base 0S. Multiple containers can run on the same virtual machine or be implemented without the use of VMs at all and run directly on hardware.
