Week 4 Worklog

Work Completed

• Designed the first high-level AWS architecture.
• Mapped user actions to AWS components: upload, process, analyze, store, retrieve.
• Studied S3 private buckets, pre-signed URLs, object prefixes, and lifecycle cleanup.

Results Achieved

• Chose Amazon S3 as the storage layer for audio, transcript, and report files.
• Defined a simple S3 prefix structure: uploads/, transcripts/, and reports/.
• Added S3 security requirements to the project proposal.

Learning Outcomes

• A storage design should include access control and cleanup policy, not only bucket creation.
• Pre-signed URLs are useful for controlled upload without making a bucket public.
