Week 8 Worklog

Work Completed

• Studied AWS Step Functions for workflow orchestration.
• Designed the async flow: create job, transcribe if needed, analyze transcript, save result, update status.
• Reviewed retry and error handling patterns.

Results Achieved

• Added Step Functions to make the processing lifecycle observable.
• Defined retryable and non-retryable failure cases.
• Planned CloudWatch logging for Lambda and Step Functions executions.

Learning Outcomes

• Orchestration makes complex serverless systems easier to debug and explain.
• Visible execution history is useful for both development and final project demonstration.
