Design Scalable Microservices Communication Pattern

Architect a resilient inter-service communication strategy for a distributed system handling 10,000+ concurrent requests. Develop a fault-tolerant mechanism using circuit breakers, exponential backoff, and message queuing that can handle network partitions and service failures. Include detailed sequence diagrams showing fallback mechanisms, retry logic, and eventual consistency protocols. Demonstrate how your design prevents cascading failures and maintains system stability under extreme load conditions.
