Key Takeaways
Architecture Decisions & Design Patterns
Architectural Decisions & Design Patterns
Architectural Principles
Design Patterns Used
Event-Driven Microservices Architecture
Problem
Need to maintain real-time data consistency across 15+ regional systems while ensuring system decoupling and scalability
Solution
Implemented event-driven microservices architecture with Apache Kafka for asynchronous data flow and independent service scaling
Rationale
Event-driven approach enables loose coupling, better fault tolerance, and allows services to scale independently based on regional demand
Trade-offs
Impact
Achieved 99.9% data consistency with sub-second propagation across all regions
Golden Record Data Strategy
Problem
Multiple regional systems contained conflicting customer data with different formats and validation rules
Solution
Implemented golden record approach with master data repository as single source of truth and intelligent conflict resolution
Rationale
Centralized approach ensures data consistency while maintaining regional flexibility for local requirements
Trade-offs
Impact
85% reduction in data inconsistencies and improved customer experience across all touchpoints
CQRS Pattern for Data Access
Problem
High-volume read operations for analytics conflicted with write-heavy transactional operations
Solution
Implemented CQRS (Command Query Responsibility Segregation) with separate read and write models
Rationale
Separates concerns and allows optimization of read and write operations independently
Trade-offs
Impact
60% improvement in query performance and 40% reduction in transaction conflicts
