Deliverables

The curriculum covers what an architect should know. This covers what an architect actually hands over: 55 artifacts, each with a worked example, a note on when it is worth producing, who reads it, and the ways it usually goes wrong. Filter by the artifact's type, the kind of engagement that calls for it, the stack or industry it is drawn against, or the audience it is written for.

IAM Role Model

Which identities may do what to which resource, expressed through roles rather than by naming people, so that access can be reviewed.

Key & Secret Management Diagram

Where keys and secrets live, what wraps what, how workloads get them without a stored credential, and how rotation actually happens.
