The document discusses microservices and cloud native architectures. It covers topics like artificial intelligence, big data, containers, and microservices. It notes that while monoliths can be good, they come with side effects like dependencies and centralized data. The document recommends using a functional programming approach with segregated data and composition over a monolithic architecture with dependencies and shared state. It also suggests choosing a language that is functional, has a type system and reactive extensions, and works with microservices frameworks and tools.
