Fat-fingered admin downs entire Joyent data center

kbsartain

Depending on the tool is not sufficient to avoid issues. Partitioning of the datacenter such that any one operation only had a potential scope of impact of, say, 1/3rd of the datacenter is a better approach. That can be accomplished through bastion hosts/gateways. It means that the admin has to log in to a unique gateway for every partition. That 2-step process is often enough of a sanity check to avoid these types of issues entirely.

The remote UI for VM administration in 2012 R2 now uses RDP protocol instead of a bitmap rendering of the desktop. that is what allows copy/paste between sessions using the normal rdp mechanasim.

I think you are confusing "vCPU's / VM" for Hyper-v and "vCPU's / Cluster" for VMWare. Both metrics might as well be a Gazillion because bother are way beyond practical limits for all known workloads.

Azure Storage makes 3 copies of all data

In the Azure documentation, they claim to make 3 synchronous writes to different storage arrays for each write i/o. Presumably, that is in a software driver stack implementation, and i would guess that it's networked storage of some sort. That would allow very cheap storage, possibly without the need for true RAID or expensive 3rd party storage vendors.
