“The Architect's Field Guide. Featuring The Khan Pattern™ for Adaptive Granularity: stop splitting, start governing.” -Vaquar Khan
📖 Microservices Recipes: The Architect's Field Guide
A practical guide to building, scaling, and managing microservices architectures
As defined by Sam Newman in his foundational text Building Microservices, microservices are "small, autonomous services that work together." This definition emphasizes the dual requirements of independence and interoperability.
