From proprietary, ad hoc solutions (EAI) toopen protocols (SOA & API), to increasinglysecure microservices, enjoy the four-phase

history of modular APIs—and the disruptivecompanies that leveraged their potential.

OpenArchitecture Era



Enterprise Application Integration (EAI) Services and ModelsLate ’90s

EAI addressed early integration and transactional challenges by using message-oriented middleware

Most platforms were integration hubs using “bus” style methods to stitch apps together

Without open protocols, proprietary platforms, and interfaces proliferated

Simplicity Era



SOA supports open protocols like SOAP and WSDL for easier integration; EAI platforms begin to adopt them

Standardized registries like UDDI automate dynamic discovery of application endpoints for consumers and publishers

Economic challenges delay adoption of critical open protocols for security, transactions, and stability

Service Oriented Architecture (SOA) and Best PracticesMid ’00s




EAI platforms start to support much of the same open standards suggested by SOA

Larger vendors like Oracle (Fusion) and SAP (PI) support smaller EAI vendors who move to support business process management

Mobility Era



REST and JSON become the mobile programming model, the de facto standard to consume back-end data

New open protocols like OAuth support security features for browser-based and native applications alike





Compared to SOA architecture, this stack proves to be light and agile while maintaining a similar feature set to SOAP/XML standards

All three generations of these technologies co-exist today in a comprehensive architecture for omnichannel digital experiences

IndependentControl Era



The world is moving toward the next generation of HTTP, forging strategies to create small, cross-platform containers that host independent microservices

New technologies like Node and Spring work well in this newer model, but advanced strategies like Docker provide isolation for di�erent services





Additional open source projects (like Hysterix for Resilience Architecture and JSON Web Tokens for key management) are filling in other pieces of the puzzle

HTTP/2 will supercharge the API economy by providing multi-call payloads in a single connection, a nascent but big move for REST technologies
