1. Module objectives （本模块目标）

   • Describe the features of WAF; （WAF特点）

   • Describe general design principles in the cloud environment; （云环境设计原则）

   • Describe pillars of WAF; （WAF的5个支柱，2021年增加到6个）

   • Describe the common uses of WAF （WAF应用）

2. Purpose of WAF （WAF的目的）

   The WAF enables the customer to make informed decisions about the architecture, in a cloud-native way, and understand the potential impact of design decisions. （WAF帮助客户决定如何搭建云原生IT系统架构，并深刻理解这些决定潜在的影响）

   The WAF provides a consistent approach to evaluating workload architecture through a set of questions, across five pillars (now six pillars) with design principles. （WAF将系统架构评估分解为5个方面/支柱，结合一组问题和设计原则，提供了一种持续的、始终如一的评估方法）

   PS. A workload is a collection of interrelated applications, infrastructure, policy, governance, and operations that provide business or operational value. （Workload是指一组提供业务和运营价值的应用程序、基础设施、业务策略、监管条例、日常运营操作的集合，简化为“系统”，WAF应用的对象就是Workload Architecture，简化为“系统架构”）

3. General design principles （设计原则）

   In a traditional environment, customers (you): （传统环境下的客户痛点）

   • Had to guess infrastructure needs, which was often based on high-level business requirements and demand. （不知道基础设施要建多大规模，因为不清楚高层次业务需求）
   • Could not afford to test at scale. (handling larger volumes) A complete duplicate of production costs is hard to
