How does a practice become a "best" practice? How does a pattern become an "anti" pattern? As always, experience is the best teacher. As Partner Solution Architects, we receive a lot of partner feedback on how practices and design patterns work—and occasionally fail to work—in the real world. We use this feedback to inform our recommendations and reference architectures. In this session, we explore a representative set of real-life "failures." We look at what these failures have to teach us about design and how to prioritize remediation of known issues.
