Building Microservices: Designing Fine-Grained Systems

The second, fully rewritten edition of the classic book on microservices. Newman treats them not as a fad but as a tool with a price: he explains how to draw service boundaries correctly, how services should communicate, and what changes in testing, deployment, security, and team structure.

The book is largely technology-agnostic, so it doesn't go stale as quickly as tutorials on Kubernetes or Kafka.
