[beqqrry-aws]

There are many examples in C++, PHP, Ruby, and Rust which need to be cleaned up to conform to current team standards. Each language has multiple services with multiple items to be cleaned.

Sub-Epics

• [ ] Add to SoS and update snippets to current standards
• [ ] Update code comments
