What are microservices and how do they differ from monolithic architectures?

Here's the answer to Question Five:

Microservices are an architectural style that structures an application as a collection of loosely coupled, independently deployable services. Each service is typically organized around a business capability, can be developed by a small, focused team, and communicates with other services through lightweight mechanisms, often using APIs. This approach contrasts with monolithic architectures where all components of an application are tightly integrated into a single unit.
