It is summed up, for me, in this quote: “The crucial architectural difference here is that vSphere wants us to stop thinking about individual physical servers, and AWS wants us to stop thinking about individual VMs.” ” It’s not just about VMotion; it’s about the bigger architectural shifts that need to be made.

Full machine virtualization offers greater isolation at the cost of greater overhead, as each virtual machine runs its own full kernel and operating system instance. Containers, on the other hand, generally offer less isolation but lower overhead through sharing certain portions of the host kernel and operating system instance.
