API-first, going beyond SOA, ESB & Integration
4 likes1,818 views
This document discusses moving towards an API-centric architecture. It defines APIs as interfaces that allow apps to access backend services and resources. It outlines how apps have evolved from thick clients to thin clients that use APIs to access resources in the cloud. It also discusses how internal and external resources are increasingly being exposed via APIs. Finally, it discusses benefits of a microservices architecture and how organizations can evolve their architectures to be API-first by exposing all services and resources via APIs.
