Monoliths: single codebase, coupled deployment, simple operational model. Microservices: independent services, independent deployment, higher operational complexity.
Benefits of microservices: team autonomy, technology heterogeneity, fault isolation, scaling flexibility. Downsides: distributed systems complexity, eventual consistency, operational overhead (monitoring, logging, tracing), network latency.
Avoid premature microservice adoption; start monolithic and break apart when justified by team growth or deployment velocity needs. Amazon, Netflix, and Uber evolved from monoliths to microservices as they scaled.
Key Takeaways
1
Monolith: Single codebase, coupled deployment, simple operations2
Microservices: Independent services, independent deployment, distributed complexity3
Benefits: Team autonomy, technology choice, fault isolation, independent scaling4
Costs: Distributed systems challenges, eventual consistency, network latency, ops overhead5
Organization Alignment: Service boundaries should match team structure (Conwayâs Law)6
Decision: Start monolithic; refactor to microservices when team growth or velocity demands itVisual Diagram
