Question
A company has a web application that uses Amazon API Gateway. AWS Lambda, and Amazon DynamoDB. A recent marketing campaign has increased demand. Monitoring software reports that many requests have significantly longer response times than before the marketing campaign. A solutions architect enabled Amazon CloudWatch Logs for API Gateway and noticed that errors are occurring on 20% of the requests. In CloudWatch, the Lambda function Throttles metric represents 1% of the requests and the Errors metric represents 10% of the requests. Application logs indicate that, when errors occur, there is a call to DynamoDB. What change should the solutions architect make to improve the current response times as the web application becomes more popular?
Options
- AIncrease the concurrency limit of the Lambda function.
- BImplement DynamoDB auto scaling on the table.
- CIncrease the API Gateway throttle limit.
- DRe-create the DynamoDB table with a better-partitioned primary index.
