Question
A company receives service requests by using an Amazon API Gateway REST API. The company needs a scalable and fault-tolerant solution to process the requests. Each request must be enhanced with data from several third-party APIs and then stored in an Amazon DynamoDB table. Processing the third-party API data can take between 1 and 30 seconds. The solution must support observability and provide robust error handling. The solution must also scale to accommodate highly variable workloads, including traffic surges of thousands of requests each second. Which solution will meet these requirements?
Options
- AUse Amazon CloudFront Functions to transform the incoming requests. Enable AWS X-Ray
- BUse an AWS Step Functions Standard Workflow and AWS Lambda functions to transform the
- CUse an AWS Lambda function to transform the requests. Use Amazon CloudWatch Logs Insights
- DUse an AWS Step Functions Express Workflow and AWS Lambda functions to transform the
Explanation
AWS Step Functions Standard Workflows are designed for long-running, durable, and scalable processes, supporting tasks that take up to 1 year. Using Lambda functions within the workflow allows integration with third-party APIs and DynamoDB. CloudWatch Logs Insights provides observability and error handling for workflow executions, making this solution fault-tolerant and suitable for high, variable workloads.
