Network Architecture and Communication Patterns Questions

Design and analysis of network architectures and service communication patterns for reliable, performant, and secure distributed systems. Topics include network topology and capacity planning, load balancing strategies, content delivery networks, caching and edge delivery, application programming interface gateway design, service to service communication patterns including synchronous and asynchronous messaging, message queues, publish subscribe, request routing, retries and backoff, timeouts, idempotency, circuit breakers, bulkheads, and service mesh considerations. Also covers latency optimization, failure modes and resilience, observability and monitoring, network security principles such as encryption and segmentation, and how architectural choices affect scalability and operational complexity.
