边缘云部署与运营：系统性实现方法

　　本书展示了一个边缘云开发路线图，一群工程师在一年的时间里遵循该路线图，开发、部署，然后全天候运营一个跨越十几家企业的边缘云，并提供了卓越的云原生服务（在我们的例子中是通过5G连接提供云服务）。该团队利用20多个开源软件和组件实现了这个边缘云和服务，但选择这些开源组件只是一个开始。在这个过程中，有几十个技术决策需要做出，还有几千行配置代码需要编写。这是一个可重复的实践，作者在本书中对此实现方案进行了详细阐述。书中的配置文件和源代码都是开源的，适用于那些想更详细地研究并实现边缘云计算和服务的读者。

　　扎克·威廉姆斯（Zack Williams） 英特尔的云软件工程师，在英特尔收购ONF工程团队后加入英特尔。在为ONF工作期间，他参与了Aether项目，并领导了基础设施团队。在加入ONF之前，他是亚利桑那大学的系统程序员。他于2001年获得亚利桑那大学计算机科学学士学位。布鲁斯·戴维（Bruce Davie）网络领域知名计算机科学家、VMware亚太区前副总裁兼首席技术官。他在VMware收购SDN（软件定义网络）初创公司Nicira后加入VMware。在此之前，他是Cisco Systems的研究员，领导一个架构师团队，负责多协议标签交换（MPLS）。他在网络行业拥有超过30年的经验，并合著了17份RFC。他于2009年成为ACM会士，并于2009年至2013年担任ACM SIGCOMM的主席。他还在麻省理工学院做了五年访问讲师，是多本书的作者，拥有40多项美国专利。
