DynamoDB Global Table Decision Scenario

In this scenario-only lab you will evaluate whether DynamoDB Global Tables are the right choice for three distinct workload profiles. No DynamoDB tables are created -- this lab focuses on analysis and decision-making.

You will:

• Read a fictional company scenario describing multi-region application requirements
• Analyze Global Tables concepts: eventual consistency, conflict resolution, replication latency, and throughput considerations
• Evaluate three workload profiles (real-time inventory, user sessions, log aggregation) against RPO and RTO requirements
• Build a structured decision matrix in markdown table format with clear justifications
• Calculate cost estimates for Global Tables versus alternatives (on-demand backup, PITR, Lambda-based replication)
• Document architecture tradeoffs including write conflicts and region management
• Write a final recommendation report with chosen approach, RPO/RTO numbers, estimated monthly cost, and operational considerations

Runs on a single AWS workstation. No multi-region DynamoDB resources are provisioned.
