AWS VPC 流量集中检测系列--(4)利用CloudFormation自动化部署AWS GWLB集成FortiGate防火墙
B站视频： https://www.bilibili.com/video/BV1LG411j7v4/?spm_id_from=333.999.0.0
上一篇文章讲过了AWS GWLB如何集成FortiGate防火墙，来对流量做集中检测。上一次实验是通过AWS 控制台操作的，这里分享一下实验环境的CloudFormation代码，帮助大家快速部署一下实验环境。
一、CloudFormation代码部署
这里的CloudFormation代码在Tokyo区域部署的，如果要在其他Region部署，请修改FortiGate和Windows2022Base的AMI ID（参考我之前的文章《如何寻找EC2特定版本的AMI ID》）。
这次CloudFormation是全自动化代码，堆栈运行完成以后，可以直接测试现象，不需要再做任何额外的配置。默认防火墙使用6.4.10的版本部署，如果要使用7.2.2参考第四部分修改关于防火墙的代码。
