Planning For Exceptions

This lesson covers exception management in application architectures, introducing four core strategies and discussing the trade-offs of each, particularly around stack trace preservation versus adding metadata. We walk through each architectural layer, recommend the most appropriate strategy per layer. Additional guidance covers logging input data for debugging, retrying failed operations, failing over to secondary systems, alerting the development team via channels like Slack or email, and presenting user-friendly business messages rather than technical details to end users.
