System Design & Production Readiness

Decompose a complex system (e.g., e-commerce platform) into microservices by applying the bounded context pattern.

Design API contracts and choose appropriate communication patterns for key inter-service interactions.

Select and justify data management strategies (e.g., CQRS, event sourcing) for different services within the system.

Explain how a service mesh (e.g., Istio) enhances observability, security (mTLS), and traffic management.

Compare the roles and trade-offs of using an API Gateway versus a service mesh.

Analyze the root cause of a simulated production incident by correlating logs, metrics, and traces.

Describe a holistic observability strategy for production, incorporating centralized logging, metrics, alerting, and tracing.

Describe common disaster recovery strategies, including multi-region deployment and data backup plans.
