summary
Operator developers get concrete guidance and tools to run multiple Operators together: an Operator Maturity Model with categories (consumability, security, robustness, portability) and guidelines used by DataStax Cassandra, PressLabs MySQL, Elastic ELK and Cert-Manager; a prototype inventory/chargeback tool QPlus that uses five CRD annotations to build resource relationship graphs and kubectl plugins to emit stack-level CPU/memory metrics; patterns and implementations for atomic stack creation, node co‑location, handling pod restarts, and accurate per-stack chargeback.
