Order Metadata Store (v0.0.1)

Long-term storage of order documents, receipts, and metadata files

The Order Metadata Store is an AWS S3 bucket that provides scalable, durable object storage for order-related documents and metadata. This storage system handles large files and documents that are associated with orders but don’t require real-time database access.

Overview

This S3-based object store serves as the primary repository for:

  • Order confirmation PDFs and receipts
  • Customer upload documents (delivery instructions, custom specifications)
  • Order processing audit trails and logs
  • Large metadata files that exceed database field limits
  • Invoice documents and tax records
  • Shipping labels and tracking documents

Security and Access Control

IAM Policies

  • OrderService Role: Full read/write access to order folders
  • ReportingService Role: Read-only access for analytics
  • CustomerService Role: Read access to customer documents
  • Compliance Role: Full access for audit purposes

Encryption

  • At Rest: AES-256 with AWS KMS
  • In Transit: TLS 1.2+
  • Key Management: Customer-managed KMS keys with automatic rotation

Access Logging

  • CloudTrail: All API calls logged
  • S3 Access Logs: Detailed request logging
  • Monitoring: CloudWatch metrics and alarms
  • Audit: Quarterly access reviews

Lifecycle Management

Automated Transitions

  1. 0-30 days: Standard storage class
  2. 30-90 days: Standard-IA (Infrequent Access)
  3. 90-365 days: Glacier storage class
  4. 1+ years: Glacier Deep Archive

Data Retention Policies

  • Order receipts: 7 years (regulatory)
  • Customer documents: 2 years (business requirement)
  • Audit trails: 5 years (compliance)
  • Invoice documents: 7 years (tax law)
  • Automated deletion: After retention period expires

Integration Patterns

Write Operations

  • Orders Service uploads receipts and confirmations
  • Customer portal uploads delivery instructions
  • Payment Service stores transaction receipts
  • Shipping Service uploads tracking labels

Read Operations

  • Customer Service retrieves order documents for support
  • Reporting Service accesses historical data
  • Compliance Service performs audit queries
  • External systems via pre-signed URLs

Monitoring and Alerting

Key Metrics

  • Upload Success Rate: > 99.9%
  • Download Latency: < 100ms (95th percentile)
  • Storage Utilization: Tracked per folder structure
  • Cost Optimization: Storage class distribution

Alerts

  • Upload failure rate > 0.1%
  • Unusual access patterns (security)
  • Storage cost increases > 20% month-over-month
  • Lifecycle policy failures

Backup and Disaster Recovery

Backup Strategy

  • Cross-Region Replication: Real-time to us-west-2
  • Versioning: 30 previous versions retained
  • MFA Delete: Required for permanent deletion
  • Point-in-Time Recovery: Via object versioning

Disaster Recovery

  • RTO: 2 hours (switch to backup region)
  • RPO: < 15 minutes (replication lag)
  • Testing: Monthly failover tests
  • Documentation: Runbooks for recovery scenarios

Cost Optimization
