☁️ What OSS/S3 Provides​

Infrastructure Management​

  • Hardware: No servers to maintain or replace
  • Networking: Global infrastructure and backbone connections
  • Scaling: Automatic capacity management (petabytes if needed)
  • Uptime: 99.9%+ availability SLA with redundancy

Data Protection​

  • Durability: 99.999999999% (11 9's) - your data won't be lost
  • Replication: Multiple copies across different locations
  • Backup: Automatic versioning and backup capabilities
  • Disaster Recovery: Geographic redundancy options

Security​

  • Encryption: Data encrypted at rest and in transit
  • Access Control: Fine-grained permissions (IAM policies)
  • Audit Logging: Track who accessed what and when
  • Network Security: VPC integration, private endpoints

Performance Features​

CDN Integration: Built-in CDN or easy integration​

  • Transfer Acceleration: Optimized upload/download speeds
  • Multipart Upload: Built-in chunked upload support
  • Intelligent Tiering: Automatic cost optimization

Management Tools​

  • Web Console: GUI for file management
  • APIs: RESTful APIs for programmatic access
  • CLI Tools: Command-line management
  • Monitoring: Built-in metrics and logging

🔧 What You Still Need to Handle​

Application Logic​

  • File organization: How you structure your folders/naming
  • Metadata management: Track file relationships in your database
  • Business rules: Who can upload/access what content
  • Workflow orchestration: Upload > process > deliver pipeline

Video-Specific Processing​

  • Transcoding: Convert between formats/qualities
  • Thumbnail generation: Create preview images
  • Content validation: Verify file types and content
  • Adaptive streaming: Create HLS/DASH manifests

User Experience​

  • Upload UI: Progress bars, error handling, resume capability
  • Video player: Playback interface and controls
  • Quality selection: Let users choose video quality
  • Offline capabilities: Download for offline viewing

Cost Optimization​

  • Lifecycle policies: When to delete or archive old content
  • Storage class selection: Hot, warm, cold storage tiers
  • Bandwidth optimization: Minimize egress costs
  • Usage monitoring: Track and optimize costs

💰 Cost Structure (What You Pay For)​

  • Storage: Amount of data stored (GB/month)
  • Requests: Number of API calls (GET, PUT, DELETE)
  • Bandwidth: Data transfer out (egress)
  • Operations: Advanced features like lifecycle management

🎯 Bottom Line​

  • OSS/S3 handles: Infrastructure, reliability, security, basic file operations
  • You handle: Business logic, video processing, user experience, cost optimization
  • Think of OSS/S3 as a reliable, scalable hard drive in the cloud - it stores your files safely and serves them quickly, but you still need to build the application logic around it.
