Isolation mode for windows containers

  • process isolation: multiple container instances run concurrently on a given host sharing the same kernel with the host as well as each other. Same as how Linux containers run.

  • Hyper-V isolation: Offers enhanced security and broader compatibility between host and container versions. With Hyper-V isolation, multiple container instances run concurrently on a host; however, each container runs inside of a highly optimized virtual machine and effectively gets its own kernel. The presence of the virtual machine provides hardware-level isolation between each container as well as the container host.
