RESTful Microservices from the Ground Up


What are RESTful Microservices and why would you want to build them? In this session you’ll learn how to to design and implement adaptable microservices that take advantage of the features of REST including statelessness, self-description, and using hypermedia to discover and modify application state.

A RESTful Microservices approach can improve the stability and resilience of services, reduces the need for extensive changes and redeployment when the domain model changes, and greatly increases the flexibility of individual services including the ability to automatically work with other newly-discovered services.

RESTful Microservices have certain characteristics and they have a clear set of dependencies on a system environment that supports runtime discovery and service-binding. Essentially services need to resolve dependencies automatically at runtime. Even service instances they have never before "met."

This session offers valuable lessons and advice for, service designers, developers, and software architects.

Key Ideas

  • The role REST can play in microservice design

  • The importance of stable interfaces in front of changing code

  • The value and challenges of supporting runtime discovery

  • How you can design for emergent adaptability w/o adding needless complexity
