Answer: AWS Lambda, AWS Step Functions

## Explanation **AWS Lambda** and **AWS Step Functions** are the correct services for creating serverless workflows: ### AWS Lambda - Serverless compute service that runs code in response to events - Executes individual functions without provisioning or managing servers - Can be triggered by various AWS services and events ### AWS Step Functions - Serverless orchestration service that coordinates multiple AWS services - Creates visual workflows using state machines - Manages the sequence and error handling of Lambda functions and other services ### Why the other options are incorrect: **Amazon Connect**: Cloud-based contact center service, not for workflow orchestration **Amazon Elastic Block Store (EBS)**: Block storage service for EC2 instances, not serverless **AWS CodeBuild**: Continuous integration service for building and testing code, not workflow orchestration ### Key Benefits of Serverless Workflows: - No server management required - Automatic scaling - Pay-per-use pricing - Built-in fault tolerance and error handling
