It is very clear Microsoft is steaming full ahead with their cloud first strategy, and as a byproduct an entire new ecosystem has been born. Managing and reporting on O365 appears to be a hot new area that will only expand from here. The below three companies have various SaaS offerings in this space. All of these offerings hook into the Microsoft portal and simplify what can be done via PowerShell. I fully expect to see the SAM tool community jump into this space through innovation or acquisition. You have to love where a need exists a solution will appear!
