Centralize Document Storage on S3
Not Started Overall Progress 0%
0 of 6 tasks completed
Tasks
- ☐ Audit current file storage locations and access patterns
- ☐ Design S3 bucket structure and lifecycle policies
- ☐ Implement S3 client library and presigned URL generation
- ☐ Migrate existing documents to S3
- ☐ Update application references to use S3
- ☐ Configure CloudFront distribution for document delivery
Overview
Consolidate all document and file storage from local disk and EFS to Amazon S3, implementing proper lifecycle policies, versioning, and CDN delivery via CloudFront.
Business Value
- Cost: S3 storage is significantly cheaper than EBS/EFS for document storage
- Durability: 99.999999999% durability for customer documents
- Scalability: Unlimited storage without capacity planning
- Performance: CloudFront CDN for fast document delivery globally
Technical Approach
Audit all file storage locations across the application. Design an S3 bucket structure with appropriate prefixes, lifecycle policies (move to IA/Glacier for old documents), and versioning. Implement a shared client library for S3 operations with presigned URLs for secure access.
Risks
- Application code changes needed wherever files are currently read from disk
- Migration of large document volumes may take extended time
- Presigned URL expiration needs careful tuning for user workflows
