protocols, and tools for building software and applications

¢ Expresses a software component in terms of its operations, inputs, outputs, and underlying types, defining functionalities that are independent of their respective implementations

API Management | What it is not!¢ API Management is not a technology or platform

¢ API Management is not ¢ Only API Lifecycle Management¢ SOA or SOA Governance¢ Integration-based architecture¢ Monolithic applications

Source: http://microservices.io/patterns/apigateway.html

It’s not just an API Gateway!


möglich


API Gateway vs. ESB (?)API Gateway¢ Acts as a central entry point to a

company

¢ Exposes public APIs

¢ Should not implement any business logic

¢ Responsible for API analytics, like usage tracking

ESB¢ Acts a central integration backbone

¢ Used internally for integrating heterogenous systems and services

¢ Should not expose functionality to the outside world

¢ Provides new internal services and APIs
