本文介绍主流服务商的认证体系，如AWS，Google Cloud，和微软Azure。
AAG三家的云技术认证都分为三个等级：入门级，助理级和专业级（包括特殊方向）。
入门级面向非IT，学生或管理层等对云缺乏基本概念的人群。 助理级面向云技术从业或打算转云的人士，要求有实操经验和一定IT经验。 专家级则是对具体某个方向的深化，也包括每个厂家擅长或独有的技术。
其实两个A厂AWS和Azure都有多门助理级认证，而谷歌GCP则把稍微有深度一点的认证都列入专业门下。 同样AWS和Azure的两个专家级认证（DevOps和架构），都需要通过相关的助理级认证为前提，而GCP的专家级都是可以直接考取的。 几家认证的相同方向有：DevOps，架构，网络，大数据，云安全，人工智能或机器学习。
