8. “Event-driven APIs are a new style
   of API that uses a subscription
   “push” model rather than the
   request-response model of
   conventional RESTful APIs.
   Architects must develop new
   approaches to mediating and
   governing event-driven APIs,
   because API management
   platforms designed only for
   RESTful APIs may not be sufficient.”
   Source: Gartner “Emerging Technologies and Trends Impact Radar: IT
   Services”, 24 Sept 2020, Twiggy Lo, Brendan Williams

   • REST APIs
   Good for for peer-to-
   peer data exchange or
   passing of control
   • Event-Driven APIs
   Good for one-to-many,
   scalable distribution of
   time-sensitive info
   • Managing both
   consistently is key to
   success

    Consume Your Business Capabilities
    • Bundles of related APIs that
    meet the needs of developers
    who serve different business
    functions
    • Produced, shared and consumed
    through a developer portal
    • Managed by a product
    manager/owner - roadmap,
    price, lifecycle
