I recently gave an introductory talk on Azure AD at a conference. I’m posting the talk here so that others can access it.
This is the PDF of the talk: 20181017-Kool-Brown-AzureAD1
This is a link to the original PPTX file along with the PDF: https://drive.google.com/drive/folders/1dm01enfTe7T0Frd6UGGfL8DSXV1YmiGu?usp=sharing
The PPTX file has a number of slide notes that expands on the content. It also has some simple animation to make the presentation a bit more interesting.
Note that I have no affiliation with Microsoft and that all of this information is gleaned from public sources. Also note that this is just a snapshot-in-time view of AAD. It is changing rapidly such that the info in this presentation will likely be out-of-date before long.
