The options involve AWS Glue, Step Functions, EC2, EventBridge, and Lambda. Key term definitions are provided to help distinguish between the services, with the correct answer being Step Functions combined with Lambda via a state machine. ## Content  A company is moving its data management application to AWS. The company wants to transition to an event-driven architecture. The architecture needs to be more distributed and to use serverless concepts while performing the different aspects of the workflow. The company also wants to minimize operational overhead. Which solution will meet these requirements? A) Build out the workflow in AWS Glue. Use AWS Glue to invoke AWS Lambda functions to process the workflow steps. B) Build out the workflow in AWS Step Functions. Deploy the application on Amazon EC2 instances. Use Step Functions to invoke the workflow steps on the EC2 instances. C) Build out the workflow in Amazon EventBridge. Use EventBridge to invoke AWS Lambda functions on a schedule to process the workflow steps. D) Build out the workflow in AWS Step Functions. Use Step Functions to create a state machine. Use the state machine to invoke AWS Lambda functions to process the workflow steps. Terms: • Glue — managed ETL — Spark jobs and a data catalog; not a workflow orchestrator • Lambda — serverless function — 15-minute hard limit, billed per millisecond of execution • Step Functions — state machine — stores the state of every step, with retry and catch built in • EC2 — virtual server — you own the OS, patching and scaling • EventBridge — serverless event bus — rules are evaluated at publish time; an event matching no enabled rule is discarded, not stored Which one?
