本文介绍使用 Terraform 执行 ECS Instance 创建、更新、删除操作。
Terraform的设计目标为Infrastructure as Code，这里的Infrastructure是一个非常抽象的东西，可以认为是数据中心的一切抽象，如二层网络、交换机(子网）、路由器、虚拟机、负载均衡、防火墙、数据库等等。

You may now begin working with Terraform. Try running "terraform plan" to see any changes that are required for your infrastructure. All Terraform commands should now work. If you ever set or change modules or backend configuration for Terraform, rerun this command to reinitialize your working directory. If you forget, other commands will detect it and remind you to do so if necessary.
