Spring Cloud AliCloud ACM 是阿里云提供的商业版应用配置管理(Application Configuration Management) 产品 在 Spring Cloud 应用侧的客户端实现，且目前完全免费。
Spring Cloud AliCloud ACM 是 Config Server 和 Client 的替代方案，客户端和服务器上的概念与 Spring Environment 和 PropertySource 有着一致的抽象，在特殊的 bootstrap 阶段，配置被加载到 Spring 环境中。当应用程序通过部署管道从开发到测试再到生产时，您可以管理这些环境之间的配置，并确保应用程序具有迁移时需要运行的所有内容。
使用 Spring Cloud AliCloud ACM，可基于 Spring Cloud 的编程模型快速接入 ACM 配置管理功能。
