Managing microservices refers to the practices and tools used to deploy, monitor, and maintain applications built as a collection of small, independent services. This approach involves orchestrating these services, ensuring their communication, and handling their lifecycle from development to retirement. It matters because it allows for greater agility, scalability, and resilience in complex software systems. For instance, an e-commerce platform might use separate microservices for user authentication, product catalog, and order processing, each managed independently. Unlike monolithic architectures where all components are tightly coupled, microservices allow for independent updates and scaling. This concept is relevant for cloud certifications like AWS Certified Solutions Architect Associate and CompTIA Cloud+.
