Coming from an AWS shop, I guess I don't understand the use case(s) for this. What this enable me to do that I couldn't accomplish by ssh'ing to any of the boxes in my environment?
A few guesses: a. It just works. No need to download and configure the right version of the SDK. b. Does not timeout when you close your laptop [I hope!]. c. I works on a Chromebook. Possibly not something you care about, but a historical pain point for the consistency of Google offerings.
I guess I still don't see the point but maybe I'm assuming that one is already running a *nix and can either jump into the terminal there or connect a VM in the cloud very easily. The convenience doesn't seem that large.
