Mediator vs OSB

Many times in my classes and projects people mix between Mediator and OSB
Now picture above tells a story :)
Mediator only works within Composite App
OSB enterprise wide integrations, SLA's etc.
Mediator and OSB do have overlapping functionality and the final differentiation:
1. OSB only used for non-functional requirements and its job is to Virtualize and route.
2. BPEL on the hand used for Orchestration between different services.

Last picture will tell a better story :)

The Department of Motor Vehicles issues drivers licenses, for example, while the Department of Homeland Security issues passports, banks track financial histories, and so on. Most of these organizations have isolated and centralized identity management systems, but the current landscape demands federation and single sign-on (SSO). This makes identity management, protection and verification very cumbersome, costly and risky for all industry enterprises and government agencies." Jai Singh Arun - Security and Blockchain Innovations Program Director, IBM Identity architectural landscape is changing and personally I can only think of this very simple analogy between identities and blockchain. Identities to the blockchain are what the bees are to the honey. . This is as simple as even your grandma would understand :) Bees (identities) all day collect honey somewhere in the fields.
