I too am a "self-declared" cloud architect...mainly Azure and Windows-based platforms for Fortune 500 companies that want MS-based cloud architectures for Exchange, SharePoint, MSSQL, and Dynamics. Sorry, but other than setting it up in a lab for my own interest and tinkering, I have not had a Client request OpenStack or any OSS if they are implementing a Microsoft technology-based cloud or hybrid-cloud architecture. Not to say F-500 companies don't use Open Source, but OSS is typically not utilized in every cloud or on-prem environment.
