Report #77346

[architecture] Small team struggling with operational complexity of distributed microservices

Build a Modular Monolith: single deployment unit with strict internal module boundaries \(package by feature, no shared DB tables between modules\); extract to services only when subteam ownership demands independent deploy cadence

Journey Context:
Microservices impose tax: distributed tracing, eventual consistency handling, schema evolution coordination, multiple CI pipelines. For <10 engineers, this slows velocity more than deployment conflicts. Modular monolith gives code isolation \(clear interfaces, separate persistence per domain\) without network boundaries. Common mistake: 'Distributed Big Ball of Mud'—extracting services that still share a database, creating the worst of both worlds \(network latency \+ tight coupling\). The boundary should be 'can this module be turned into a service by changing import to HTTP call?' If not, fix the coupling first.
