标题“Microservice for the enterprise”与描述中所含的知识点极为丰富,尤其针对企业级应用环境下微服务架构的设计与实现。在此,我们将其内容展开,细分为以下核心部分: ### 微服务架构原则 微服务架构是一种将单一应用程序作为一套小型服务开发的方法,每个服务运行在自己的进程中,并围绕业务能力组织,通常使用轻量级的通讯机制,例如HTTP资源API。这类架构能够独立部署、扩展与修复,其核心理念是将大型应用拆分为一组松耦合的服务,让每个服务能专注于完成一个单一任务。 ### 微服务在现实场景的应用 企业应用的微服务化不仅需要理解理论,更重要的是将理论应用到实际问题中。书中通过使用案例来说明如何在企业应用环境中构建微服务,特别强调了在既有遗留系统(brownfield environment)中实施微服务的重要性,以确保业务运行的连续性。 ### 微服务的架构挑战与解决方案 微服务架构带来的挑战包括服务间的集成、API管理、数据一致性、服务安全等方面。企业中采用微服务架构时,往往需要解决如何在没有中央集成总线(ESB)的情况下实现服务集成。解决方案包括使用复合/集成微服务来处理服务间的集成。 ### 微服务的关键技术 - **消息技术(Messaging Technologies)**:微服务之间需要通过消息传递机制来通信,这包括同步和异步消息传递、消息队列、事件总线等。 - **服务网格(Service Mesh)**:作为微服务架构中解决服务间通信挑战的一种模式,服务网格提供了一种实现服务发现、负载均衡、故障恢复、安全性和监控的透明基础架构层。 - **微服务安全模式(Microservices Security Patterns)**:在真实世界场景中处理安全问题,包括认证、授权、加密通信、安全API网关等。 - **API管理、分布式数据管理和可观察性(API Management, Decentralized Data Management, Observability)**:如何有效地管理API、处理分散数据和监控微服务的运行状态,是微服务架构中的关键组成部分。 ### 微服务的组织结构 对服务进行分类,如核心服务和原子服务、复合服务与集成服务、API与边缘服务,这些分类有助于更好地组织和管理微服务。核心服务是业务的主要部分,而原子服务则提供基本的操作。复合服务通常是由多个服务组合而成,而集成服务则更多是用于服务间的集成。API与边缘服务强调的是如何通过API网关来暴露服务。 ### 微服务的设计过程 设计微服务架构时,需要遵循一定的步骤和原则,书中应会详细说明如何进行微服务设计,包括服务的划分、识别边界、通信协议的选择、数据管理策略等。 ### 面向的对象 此书主要针对需要实现微服务架构的应用程序开发人员与DevOps工程师,以及负责设计此类系统的架构师和分析师。 通过这些内容,读者可以获得微服务架构的全面理解,并掌握如何在企业环境中实践这些现代技术。从微服务的组织分类到实际部署中的挑战应对,再到服务间的通信与安全,本资料为开发和运维人员提供了一条清晰的学习与实践路径。

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 service integration and 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/integration microservices. 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 applications with minimal disruption to your business. Microservices for the Enterprise 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. What You'll Learn Design and develop microservices architectures with confidence Put into practice the most modern techniques around messaging technologies Apply the Service Mesh pattern to overcome inter-service communication challenges Apply battle-tested microservices security patterns to address real-world scenarios Handle API management, decentralized data management, and observability Who This Book Is For Developers and DevOps engineers responsible for implementing applications around a microservices architecture, and architects and analysts who are designing such systems

Summary Enterprise Java Microservices is an example-rich tutorial that shows how to design and manage large-scale Java applications as a collection of microservices. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology Large applications are easier to develop and maintain when you build them from small, simple components. Java developers now enjoy a wide range of tools that support microservices application development, including right-sized app servers, open source frameworks, and well-defined patterns. Best of all, you can build microservices applications using your existing Java skills. About the Book Enterprise Java Microservices teaches you to design and build JVM-based microservices applications. You'll start by learning how microservices designs compare to traditional Java EE applications. Always practical, author Ken Finnigan introduces big-picture concepts along with the tools and techniques you'll need to implement them. You'll discover ecosystem components like Netflix Hystrix for fault tolerance and master the Just enough Application Server (JeAS) approach. To ensure smooth operations, you'll also examine monitoring, security, testing, and deploying to the cloud. What's inside The microservices mental model Cloud-native development Strategies for fault tolerance and monitoring Securing your finished applications About the Reader This book is for Java developers familiar with Java EE. About the Author Ken Finnigan leads the Thorntail project at Red Hat, which seeks to make developing microservices for the cloud with Java and Java EE as easy as possible. Table of Contents Part 1.
