Interviewer [00:00:05]: Design a microservices architecture for an e-commerce platform that needs to handle 100,000 concurrent users and process 10,000 orders per hour.
You [00:00:15]: I'd like to start by understanding the key requirements and constraints. What are the main functional areas we need to cover? Are there any specific performance, scalability, or reliability requirements? And what's the expected growth trajectory?
Interviewer [00:00:28]: Good questions. The platform needs to support product catalog, inventory management, user accounts, shopping cart, order processing, payments, and recommendations. We need 99.99% availability for critical paths like checkout and payment. The platform is expected to grow by 30% year-over-year in terms of users and order volume.
AI Suggestion:
- Domain-Driven Microservices:
- Propose bounded contexts for key domains: Product, Inventory, User, Cart, Order, Payment, Recommendation
- Suggest service boundaries based on business capabilities and data ownership
- Discuss event-driven communication between domains (e.g., OrderCreated, PaymentProcessed)
- Cloud-Native Architecture:
- Recommend containerization with Kubernetes for orchestration
- Discuss service mesh (Istio/Linkerd) for inter-service communication
- Suggest API gateway pattern for external clients
- Mention infrastructure-as-code for environment consistency
- Data Management:
- Explain database-per-service pattern with appropriate DB types (SQL/NoSQL)
- Discuss CQRS for high-read services like product catalog
- Suggest event sourcing for order processing
- Mention data consistency patterns (Saga pattern for distributed transactions)
- Scalability & Resilience:
- Explain auto-scaling strategies for variable load
- Discuss circuit breakers and bulkheads for fault isolation
- Suggest caching strategies (Redis/CDN) for product catalog
- Mention blue-green deployments for zero-downtime updates
- Observability & Operations:
- Recommend distributed tracing (Jaeger/Zipkin)
- Discuss centralized logging and monitoring
- Suggest SLOs/SLIs for critical services
