-This module creates an S3 bucket suitable for receiving logs from other `AWS` services such as `S3`, `CloudFront`, and `CloudTrails`, which generate an enormous amount of log data. It implements a configurable log retention policy, which allows you to efficiently manage logs across different storage classes (_e.g._ `Glacier`) and ultimately expire the data altogether.
