这个AWS解决方案构造实现了（1）配置为向队列发送消息的AWS Lambda函数；（2）Amazon SQS队列；（3）配置为使用队列中的消息的AWS Lambda函数。在
以下是Typescript中的最小可部署模式定义：

默认设置
此构造的现成实现（没有任何重写属性）将遵循以下默认值：
AWS Lambda函数
- 为Lambda函数配置有限权限访问IAM角色。在
- 启用NodeJs Lambda函数的Keep Alive重用连接。在
- 启用X射线跟踪
Amazon SQS队列
- 为主队列部署死信队列。在
- 使用AWS-s主密钥服务器对主密钥队列启用加密。在
- 对传输中的数据进行加密
