IEFRA2 — Strengths Sec 1.7.2

9.2 Strengths
Clearly defines the emphasis on interoperability—highlights that IEF services communicate via standard messages over a secure messaging bus (SMB). Provides flexibility for multiple vendors and best-of-breed solutions—ensuring that users aren’t locked into proprietary systems. Acknowledges scalability needs—mentions horizontal and vertical scaling for large data environments (e.g., IoT, data lakes).
Supports both interoperable and integrated implementations—leaves room for integrated systems and appliances, rather than forcing only service-based architectures.
