If you’re using AWS Lambda to consume records from Amazon DynamoDB, Amazon Kinesis, Apache Kafka, and Amazon SQS, the event source mapping (ESM) takes care of reading from the event source and invoking the Lambda function. The ESM also provides valuable features that can optimize the performance, failure handling, and retry behaviors of your application.

When you build on AWS, the AWS Well-Architected Framework provides a workload-agnostic consistent approach to help you evaluate architectures and implement designs that scale over time. If you are using or planning to use AWS serverless, you have to extend that evaluation to include the specific technology domains around serverless workloads.
