虚拟化、云、容器、服务器自动化以及软件自定义网络的初衷是简化IT运维，然而应用了这些技术之后，很多组织发现它们不断增长，蔓延成了一个无法管理的系统。这正是基础设施即代码的用武之地。在这本务实的指导之作中，来自ThoughtWorks的Kief Morris展示了如何有效地使用DeV0ps运动所倡导的原则、时间和模式，来管理云时代的基础设施。

　　对于系统管理员、基础设施工程师、团队领袖以及架构师来说，这是一本难得的佳作。它描述了可以用来实现基础设施即代码的多种工具、技巧和模式。在基弗·莫里斯著的这本《基础设施即代码(影印版)(英文版)》的三个部分中，你将学习用来创建和配置基础设施元素的平台和工具、使用这些工具的模式以及在你自身环境中落实基础设施即代码的实践。

　　检查那些当企业采用新一代基础设施技术时常掉入的陷阱

　　理解动态基础设施平台的能力和服务模型

　　学习提供、开通和配置核心基础设置资源的工具

　　探索管理动态基础设施的服务和工具

　　学习开通服务器、构建服务器模板和更新运行时服务器的特定模式和实践
