How would you handle a practical scenario involving Service Discovery in Microservices Architecture?
For a practical scenario involving Service Discovery, I would first clarify the business goal, scale, constraints, and the failure or quality attribute being tested. Service discovery enables services or platforms to locate healthy service instances dynamically. The scenario centers on how service discovery differs between Kubernetes, ECS, and VM-based microservice environments. For production, use platform-native discovery where possible, combine it with health checks and load balancing, and keep DNS or registry behavior observable. I would then compare the main alternatives and tradeoffs, identify likely failure modes, and explain how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
