From Virtual Machines to Containers: When to Use Which | Virtualization Part 22

Why are so many teams moving to containers, and does that mean virtual machines are going away? This lesson walks the path from bare metal to VMs to containers and explains where each one fits. We start with the pre-virtualization hardware problem, then revisit how virtual machines abstract hardware through the hypervisor. From there we look at the container evolution, where the OS itself is abstracted with a shared kernel, OS-level virtualization, millisecond startup, and high density. We do a head-to-head architectural comparison of VMs and containers, talk through how workload dictates choice, and close with the mental shift to disposable infrastructure, container images, and immutable deployments.
