Granularity and Communication in Microservices Architectures - Neal Ford

This talk focuses on the challenges teams face regarding the communication between microservices, often leading to a disorganized structure known as a "Big Ball of Mud." Neal Ford introduces the architecture quantum, a fundamental unit of architectural measurement that aids in identifying communication boundaries and assessing both static and dynamic coupling. Attendees gain practical techniques for determining optimal service granularity by using integrators and disintegrators, along with insights on choosing between synchronous and asynchronous communication models while balancing consistency and transactional behavior. The session also delves into eight distinct saga patterns, offering guidance on their effective application in distributed systems.
