AWS DynamoDB, a fully managed NoSQL database service, provides high performance and scalability for applications. While DynamoDB offers incredible capabilities, it is important to implement cost-saving strategies to optimize the usage of DynamoDB tables. In this article, we will explore some techniques and technical approaches to save costs on AWS DynamoDB tables while maintaining performance and scalability.

Right-Sizing Provisioned Capacity

To optimize costs, accurately estimate the required provisioned capacity for your DynamoDB tables. Provisioned capacity requires specifying a fixed number of read and write units. Monitor your application’s traffic patterns using Amazon CloudWatch metrics and DynamoDB’s built-in dashboard. Analyze the data and adjust the provisioned capacity based on the observed usage patterns. By avoiding overprovisioning and underutilization, you can significantly reduce costs associated with provisioned throughput.
