Granularity & Communication for Microservices Architectures
summary
Explains a concrete tradeoff method for microservice granularity using five disintegrators and three integrators to iterate service boundaries, shows how database and workflow coupling force re-bundling, and models dynamic coupling as a three‑dimensional space (communication, consistency, coordination). Maps all eight saga patterns (epic, fantasy, orchestrated, parallel, time travel, anthology and the anti‑pattern horror story saga), compares complexity, responsiveness and scalability, and gives heuristics for choosing orchestration vs choreography and sync vs async.
