MLA-C01 Deployment and Orchestration of ML Workflows Practice Question
An ML engineer needs to orchestrate a multi-step workflow that includes data preprocessing on Spark, model training on SageMaker, and deployment to a production endpoint. They require tight integration with other AWS services and the ability to add custom logic. Which AWS service should they use alongside SageMaker?
⚠ Common exam trap
A common mix-up: candidates confuse SageMaker Pipelines (a SageMaker-native orchestrator) with a general-purpose orchestrator, overlooking the requirement for tight integration with non-SageMaker services like Spark and custom logic — Step Functions is the correct choice for heterogeneous, multi-service ML workflows.

Correct answer & explanation
✓
AWS Step Functions
AWS Step Functions is the correct choice because it provides a serverless workflow orchestration service that can coordinate multi-step ML pipelines involving Spark on AWS Glue or EMR, SageMaker training jobs, and endpoint deployments. It offers tight integration with over 200 AWS services via direct SDK integrations, supports custom logic through Lambda functions, and includes built-in error handling, retries, and parallel execution — making it ideal for complex, heterogeneous ML workflows that extend beyond SageMaker's native capabilities.
