While both API and SOA have similar business and technical goals, many API proponents continue to describe APIs as a significantly different approach with little connection to SOA. They often promote a deep and divisive schism between pragmatic REST APIs and SOA. The division inhibits cleanly integrating SOA services and RESTful APIs into a unified architecture.
Achieving Service Oriented Architecture initiative success requires creating loosely coupled consumer-provider connections, enforcing a separation of concerns between consumer and provider, exposing a set of re-usable, shared services, and gaining service consumer adoption. Many development teams publish SOA services, yet struggle to create a service architecture that is widely adopted.
