Key Decisions & Trade-offs¶

Chose Kubernetes over ECS
Pro: Better portability and ecosystem
Con: Higher operational complexity
Mitigation: Invested in team training and managed services
Synchronous vs Asynchronous Communication
Chose event-driven for non-critical paths
Maintained synchronous for payment processing
Result: Better fault isolation with acceptable complexity
Database per Service vs Shared
Started with shared DB, moved to isolated
Implemented saga pattern for distributed transactions
Trade-off: Consistency complexity for better scalability
