SAP support has been doing this for over a decade
This may be news for Microsoft, but SAP has had this type of system in place for well over 10 years, only instead of it being in a "cloud", it was SAP's support system connected over the Internet (and private lines like Frame Relay and MPLS) to enteprise customer's systems. Every access was logged, tracked, and could be audited at any time by customers in near real time.
My question is, why wasn't a support system like this in place years ago for Microsoft's enterprise customers? Why is it restriced to Office365 today?
