Hands-On Serverless Computing

Data processing

You can have AWS Lambda functions execute code as a response to events and triggers such as those in the data store, changes to system state, or any action performed by users. You can have AWS Lambda directly triggered by different AWS services such as S3, SNS, DynamoDB, CloudWatch, and Kinesis. AWS also has a service called AWS Step Functions (https://aws.amazon.com/step-functions/), through which you can orchestrate multiple AWS Lambda instances and build a workflow.
