The Advanced IT Architect Development Council (AITAC) is a council established to develop "architect human resources" who will support IT infrastructure in the IoT era, and provides educational content to many companies. In the future, regardless of the size of the company that provides social infrastructure, the system (cyber-physical system) will be even more advanced IT. On the other hand, not all IT is successful. What makes the difference between success and failure is "human resources". In this talk, we will explain the IT architects that AITAC aims to cultivate, its importance, and the introduction and characteristics of the content provided by AITAC.
