Anyone operating a cloud of remotely interesting size will need DTrace, or, if they use Linux, eBPF tracing. It was a foregone conclusion that Microsoft needed DTrace. Microsoft surely also needed it for other reasons. Developers, sysadmins, and power users -- all need DTrace or DTrace-like tools. We're finally leaving the dark ages of unobservable operating systems! Hooray! We should all give huge thanks to the creators of DTrace, Mike Shapiro, Bryan Cantrill, and Adam Leventhal, as well as Brendan Gregg and all of the crew at http://dtrace.org http://dtrace.org.
