VM's vs Containers
Last updated

OS-level virtual machines (e.g. Xen):
Do not make virtualization completely available at the OS level:
Only the OS services are virtual.
Host Kernel: Virtualizes its services in isolation from its tenants.
Isolates the execution environment of one or more processes.
To consider:
Isolation/Visibility: limit what can be seen by the tenants.
Resource control: limit resource consumption.
Portability: can reconstruct the same environment in multiple hosts.
Container-based virtualization depends on OS mechanisms to reach application isolation.
