The document discusses microservices and continuous delivery. It begins by defining microservices and distinguishing them from monolithic applications and traditional SOA. It then discusses how microservices enable continuous delivery by decoupling capabilities and change cycles. This allows individual teams to own the full lifecycle of the capabilities they build and operate. The document also addresses some challenges of microservices such as service registration and discovery, load balancing, and fault tolerance which can be helped by platforms like Spring Cloud and Netflix OSS. It emphasizes that microservices require operationalization and significant DevOps skills.
