Explanation
Amazon EventBridge is the correct service for this requirement because:
-
EventBridge is an AWS serverless event bus service that helps you connect applications using data from your own applications, integrated Software-as-a-Service (SaaS) applications, and AWS services
-
It can monitor AWS service events, including EC2 instance state changes
-
When an EC2 instance transitions to the RUNNING state, EventBridge can detect this event and trigger a Step Functions workflow
-
This provides a decoupled, event-driven architecture where the EC2 state change automatically initiates the workflow without manual intervention
Why the other options are incorrect:
-
Amazon SageMaker: A machine learning service for building, training, and deploying ML models
-
Amazon Connect: A cloud-based contact center service
-
AWS Fargate: A serverless compute engine for containers that works with Amazon ECS and EKS
EventBridge is specifically designed for event-driven architectures and can integrate with Step Functions to automate workflows based on AWS service events.
