Building Resilient .NET Applications Using Amazon DynamoDB Warm Throughput

This article demonstrates how to use Amazon DynamoDB warm throughput to prepare .NET applications for planned traffic spikes by pre-warming tables and scaling provisioned capacity in advance.

• Warm throughput pre-warms DynamoDB tables so provisioned capacity scales up in seconds instead of minutes when demand spikes instantaneously
• Sample .NET application simulates course launch notifications, comparing workload performance with and without warm throughput
• Calculate peak capacity by determining concurrent operations and RCUs per operation, then set warm throughput before the planned event
• CloudWatch metrics show zero throttle events with warm throughput versus significant throttling without it
• Ideal for scheduled events, batch processing, migrations, and seasonal traffic where timing and volume are known in advance

Warm throughput enables .NET applications to handle instantaneous traffic spikes without throttling by preparing DynamoDB tables hours or days before planned events.
