Challenges & Solutions
Cost Optimization
Managing AWS costs while maintaining performance for large media files.
Solution:
Implemented S3 lifecycle policies to move infrequently accessed files to cheaper storage tiers, used CloudFront CDN to reduce S3 bandwidth costs, and optimized DynamoDB throughput with on-demand pricing.
Access Control Complexity
Managing different permission levels for various user types and use cases.
Solution:
Designed flexible IAM role system with pre-signed URLs for temporary access, implemented request signing for API authentication, and created permission inheritance model for organizational structures.
Metadata Query Performance
Fast querying of millions of media items by various metadata attributes.
Solution:
Designed efficient DynamoDB schema with Global Secondary Indexes (GSI) for common query patterns, implemented caching layer for frequently accessed metadata, and used DynamoDB Streams for real-time updates.
