This is a live blog of session DATS004, titled “Bare-Metal, Docker Containers, and Virtualization: The Growing Choices for Cloud Applications.” Weaver includes a discussion of the drivers behind virtualization as well as the pros and cons of virtualization. That, naturally, leads to a discussion of containers.
