A company that operates quick-service restaurants experiences high sales traffic for 4 hours daily, with lower traffic outside these peak hours. Their point of sale and management platform, hosted on AWS, utilizes Amazon DynamoDB with a backend configured for provisioned throughput mode, set at 100,000 RCUs and 80,000 WCUs to accommodate peak usage. The company seeks to minimize DynamoDB costs and reduce IT operational overhead. Which solution offers the most cost-effective approach to achieve these goals?
Explanation:
The most cost-effective solution for the company is to switch the DynamoDB table to on-demand capacity mode. This approach provides the flexibility to automatically scale up or down based on the current traffic, which can help reduce costs during non-peak hours compared to using provisioned throughput mode. On-demand capacity also minimizes the operational overhead since it eliminates the need to manage the provisioned capacity manually. Therefore, Option B is the correct answer.
