Configuring DynamoDB Capacity and Auto Scaling

Managing database performance and costs can be a delicate balancing act when application traffic fluctuates. Understanding how to scale your database infrastructure dynamically ensures your application remains responsive without overspending on unused resources. This text-based course guides you through the core concepts of DynamoDB capacity management, from foundational read and write capacity units to implementing automated scaling policies. You will gain the confidence to analyze workload patterns and configure optimal scaling behaviors using both the web console and programmatic SDK tools. What you'll learn: Understand the core differences between provisioned capacity and on-demand capacity modes; Calculate Read Capacity Units (RCUs) and Write Capacity Units (WCUs) for various payload sizes; Configure DynamoDB Auto Scaling to dynamically adjust to traffic spikes and quiet periods; Implement capacity management programmatically using the AWS SDK and command-line tools; Monitor capacity utilization and throttling events using CloudWatch metrics; Apply cost-optimization strategies to prevent over-provisioning while maintaining high availability. The course begins with essential database definitions and capacity calculation formulas, then moves step-by-step through manual provisioning, setting up auto-scaling policies, and managing capacity via code. Designed for beginners to cloud databases and developers looking to master AWS database scaling, with no advanced prerequisites required.
