图2-4：通过FaaS模型来部署Java应用程序。在这种模型下，代码会被打包到一个JAR或者ZIP文
件中，然后通过底层的平台（通常是容器平台）进行部署和管理
平台对持续交付的影响
开发人员经常会问，应用程序构件在各个平台上的打包格式，是否会影响持续交付的实
施。我们对这个问题的回答，就像回答任何有趣的问题一样
—
“看情况”。答案既是
肯定的，因为打包格式明显会影响一个构件的构建、测试和运行方式，而它们都跟构建
管道的流程和技术实现有关（甚至也可能与目标平台的集成有关）。
但是，答案也是否
定的，因为持续交付一个有效构件的核心概念、原则和结论依然保持不变。
在本书中，我们不仅会抽象地介绍核心概念，也会在适当的情况下，提供胖
JAR
文件、
容器镜像和
FaaS
函数这三种打包风格的具体示例。

在过去的十年中，我们已经看到软件开发中的各个角色正在发生变化，尤其是他们开始
共同承担一些责任。我们现在开始讨论一些新的方法和理念，并分享我们如何理解它们
与持续交付之间的相互影响。
