(dev here) Hey, to clarify: "Say goodbye to slow, clunky containers and VMs" refers to the fact that we support running both Docker containers and Linux machines, not that the Docker engine doesn't use a VM under the hood.

And yes, there is still a VM, but the experience and architecture are very different from traditional full Linux VMs that we're describing with "slow, clunky".

Running all your instances in separate VMs vs using a single VM to host containers is a completely different paradigm, especially when it comes to performance. This is even more true for performance between instances.

So I personally don't find "say goodbye to VMs" to be misleading.
