Microservices for the Enterprise | Kasun Indrasiri, Prabath Siriwardena

Understand the key challenges and solutions around building microservices in the enterprise application environment. This book provides a comprehensive understanding of microservices architectural principles and how to use microservices in real-world scenarios. Architectural challenges using microservices with API management are presented and you learn how to eliminate the use of centralized integration products such as the enterprise service bus (ESB) through the use of composite services. Concepts in the book are supported with use cases, and emphasis is put on the reality that most of you are implementing in a "brownfield" environment in which you must implement microservices alongside legacy architecture with minimal disruption to your business. Also included are emerging microservices architecture patterns such as the service mesh and anti-corruption layer patterns. Microservices for the Enterprise begins with a discussion of microservices architectures and their flexibility over monolithic architectures. The book covers state-of-the-art techniques around microservices messaging, service development and description, service discovery, governance, and data management technologies and guides you through the microservices design process. Also included is the importance of organizing services as core versus atomic, composite versus integration, and API versus edge, and how such organization helps to eliminate the use of a central ESB and expose services through an API gateway. The book also covers microservices deployment patterns with technologies such as Docker and Kubernetes, along with continuous integration and continuous deployment (CI-CD) techniques. Microservices administration is presented with a discussion of metrics, monitoring, distributed logging, and distributed tracing.
