These questions cover a range of topics, from basic concepts to advanced strategies, and are designed to test the depth and breadth of an experienced professional's knowledge in microservices and distributed systems.   General Microservices Concepts What are microservices? How do they differ from monolithic architecture? Answer : Microservices are a design approach where an application is composed of loosely coupled services. Each service is fine-grained and performs a single function. Unlike monolithic architecture, where the entire application is built as a single unit, microservices allow for independent development, deployment, and scaling of each service.
