一、服务建模切入点一：服务分类

（一）、服务的基本类别：工具服务+实体服务+任务服务

（二）、从业务维度对服务做层次分类：基础服务+通用服务+定制服务+其他服务

二、服务建模切入点二：服务模型

（一）、服务的概念模型维度：服务标准+服务级别

（二）、服务统一表现形式：服务契约化+文档服务

三、服务建模切入点三：服务边界

（一）、识别业务领域及边界：通用语言+子域+聚合

（二）、界限上下文：领域与界限上下文+界限上下文集成策略

领域与界限上下文

界限上下文集成策略

（三）、服务边界划分的四大原则

四、服务建模切入点四：服务数据

（一）、数据去中心化的三大场景

跨表查询场景解决

跨库查询场景解决

技术耦合场景及解决

（二）、数据去中心化流程

步骤1：代码分离

步骤2：重复数据库模式：代码拆分后，对数据访问会形成两种模式

步骤3：迁移数据读写操作

步骤4：抽离服务化接口

五、总结思考

参考书籍及文献：

干货分享，感谢您的阅读！

随着互联网技术的飞速发展，微服务架构作为一种灵活、高效的系统设计模式，已经成为许多企业构建可扩展、高可用应用的首选方案。然而，微服务架构的成功不仅依赖于技术的选择，更依赖于如何科学地进行服务建模。如何将复杂的业务需求抽象成一系列高内聚、低耦合的服务？如何确保服务间的协作和数据的一致性？这些问题往往成为微服务架构设计中的瓶颈。

本篇文章将带您深入探索微服务架构中的服务建模切入点。从服务分类到服务模型，从服务边界的识别到数据去中心化，我们将通过一系列具体的切入点，帮助您在设计微服务架构时，能够更好地理解和把握服务的内在关系。无论您是初次接触微服务架构的开发者，还是已有一定经验的架构师，都能从中获得启发与实践指导，进一步优化您的微服务设计。

让我们一起走进微服务的世界，解锁架构设计的秘密。
