+# Backend Performance & Production Features - Implementation Summary
+
+## Overview
+
+This document summarizes the implementation of 5 backend tasks for mockupAWS v1.0.0 production release.
+
+---
+
+## BE-PERF-004: Redis Caching Layer ✅

+- `redis.conf` - Redis server configuration
+
+### Features
+1. **Redis Setup**
+   - Connection pooling (max 50 connections)
+   - Automatic reconnection with health checks
+   - Persistence configuration (RDB snapshots)
+   - Memory management (512MB max, LRU eviction)
+
+2. **Three-Level Caching Strategy**
+   - **L1 Cache** (5 min TTL): DB query results (scenario list, metrics)
+   - **L2 Cache** (1 hour TTL): Report generation (PDF cache)
+   - **L3 Cache** (24 hours TTL): AWS pricing data
+
+3. **Implementation Features**
+   - `@cached(ttl=300)` decorator for easy caching
+   - Automatic cache key generation (SHA256 hash)
+   - Cache warming support with distributed locking
+   - Cache invalidation by pattern
+   - Statistics endpoint for monitoring
+
+### Usage Example
+```python
+from src.core.cache import cached, cache_manager
+
+@cached(ttl=300)
+async def get_scenario_list():
+    # This result will be cached for 5 minutes
+    return await scenario_repository.get_multi(db)
+
+# Manual cache operations
+await cache_manager.set_l1("scenarios", data)

+
+## Overview
+
+This document describes the backup, restore, and disaster recovery procedures for the mockupAWS PostgreSQL database.
+
+### Components
+
+- **Automated Backups**: Daily full backups via `pg_dump`
+- **WAL Archiving**: Continuous archiving for Point-in-Time Recovery
+- **Encryption**: AES-256 encryption for all backups
+- **Storage**: S3 with cross-region replication
+- **Retention**: 30 days for daily backups, 7 days for WAL archives
+
+---
+
+## Recovery Objectives
+
+| Metric | Target | Description |
+|--------|--------|-------------|
+| **RTO** | < 1 hour | Time to restore service after failure |
+| **RPO** | < 5 minutes | Maximum data loss acceptable |
+| **Backup Window** | 02:00-04:00 UTC | Daily backup execution time |
+| **Retention** | 30 days | Backup retention period |
+
+---
+
+## Backup Strategy
+
+### Backup Types
+
+#### 1. Full Backups (Daily)
+
+- **Schedule**: Daily at 02:00 UTC
+- **Tool**: `pg_dump` with custom format
+- **Compression**: gzip level 9
+- **Encryption**: AES-256-CBC
+- **Retention**: 30 days
+
+#### 2. WAL Archiving (Continuous)
+
+- **Method**: PostgreSQL `archive_command`
+- **Frequency**: Every WAL segment (16MB)
+- **Storage**: S3 nearline storage
+- **Retention**: 7 days
+
+#### 3. Configuration Backups
+
+- **Files**: `postgresql.conf`, `pg_hba.conf`
+- **Schedule**: Weekly
+- **Storage**: Version control + S3
+
+### Storage Architecture
+

+
+### Required Environment Variables
+
+```bash
+# Required
+export DATABASE_URL="postgresql://user:pass@host:5432/dbname"
+export BACKUP_BUCKET="mockupaws-backups-prod"
+export BACKUP_ENCRYPTION_KEY="your-256-bit-key-here"
+
+# Optional
+export BACKUP_REGION="us-east-1"
+export BACKUP_SECONDARY_REGION="eu-west-1"
+export BACKUP_SECONDARY_BUCKET="mockupaws-backups-dr"

+```
+
+---
+
+## Restore Procedures
+
+### Quick Reference
+
+| Scenario | Command | ETA |
+|----------|---------|-----|
+| Latest full backup | `./scripts/restore.sh latest` | 15-30 min |
+| Specific backup | `./scripts/restore.sh s3://bucket/path` | 15-30 min |
+| Point-in-Time | `./scripts/restore.sh latest --target-time "..."` | 30-60 min |
+| Verify only | `./scripts/restore.sh <file> --verify-only` | 5-10 min |
+
+### Step-by-Step Restore
+
+#### 1. Pre-Restore Checklist
+
+- [ ] Identify target database (should be empty or disposable)
+- [ ] Ensure sufficient disk space (2x database size)
+- [ ] Verify backup integrity: `./scripts/restore.sh <backup> --verify-only`
+- [ ] Notify team about maintenance window
+- [ ] Document current database state
+
+#### 2. Full Restore from Latest Backup
+
+```bash
+# Set environment variables
+export DATABASE_URL="postgresql://postgres:password@localhost:5432/mockupaws"
+export BACKUP_ENCRYPTION_KEY="your-encryption-key"
+export BACKUP_BUCKET="mockupaws-backups-prod"
+
+# Perform restore
+./scripts/restore.sh latest
+```
+
+#### 3. Restore from Specific Backup
+
+```bash
+# From S3
+./scripts/restore.sh s3://mockupaws-backups-prod/backups/full/20260407/backup.enc
+
+# From local file
+./scripts/restore.sh /path/to/backup/mockupaws_full_20260407_120000.sql.gz.enc
+```
+
+#### 4. Post-Restore Verification
+
+```bash
+# Check database connectivity
+psql $DATABASE_URL -c "SELECT COUNT(*) FROM scenarios;"
+
+# Verify key tables
+psql $DATABASE_URL -c "\dt"
+
+# Check recent data
+psql $DATABASE_URL -c "SELECT MAX(created_at) FROM scenario_logs;"
+```
+
+---
+
+## Point-in-Time Recovery (PITR)
+
+### Prerequisites
+
+1. **Base Backup**: Full backup from before target time
+2. **WAL Archives**: All WAL segments from backup time to target time
+3. **Configuration**: PostgreSQL configured for archiving
+
+### PostgreSQL Configuration
+
+Add to `postgresql.conf`:
+
+```ini
+# WAL Archiving
+wal_level = replica
+archive_mode = on
+archive_command = 'aws s3 cp %p s3://mockupaws-wal-archive/wal/%f'
+archive_timeout = 60
+
+# Recovery settings (applied during restore)
+recovery_target_time = '2026-04-07 14:30:00 UTC'
+recovery_target_action = promote
+```
+
+### PITR Procedure
+
+```bash
+# Restore to specific point in time
+./scripts/restore.sh latest --target-time "2026-04-07 14:30:00"
+```
+
+### Manual PITR (Advanced)
+
+```bash
+# 1. Stop PostgreSQL
+sudo systemctl stop postgresql
+
+# 2. Clear data directory
+sudo rm -rf /var/lib/postgresql/data/*
+
+# 3. Restore base backup
+pg_basebackup -h primary -D /var/lib/postgresql/data -Fp -Xs -P
+
+# 4. Create recovery signal
+touch /var/lib/postgresql/data/recovery.signal
+
+# 5. Configure recovery
+cat >> /var/lib/postgresql/data/postgresql.conf <<EOF
+restore_command = 'aws s3 cp s3://mockupaws-wal-archive/wal/%f %p'
+recovery_target_time = '2026-04-07 14:30:00 UTC'
+recovery_target_action = promote
+EOF
+
+# 6. Start PostgreSQL
+sudo systemctl start postgresql
+
+# 7. Monitor recovery
+psql -c "SELECT pg_last_wal_receive_lsn(), pg_last_wal_replay_lsn(), pg_last_xact_replay_timestamp();"
+```
+
+---
+
+## Disaster Recovery Procedures
+
+### DR Scenarios
+
+#### Scenario 1: Database Corruption
+
+```bash
+# 1. Isolate corrupted database
+psql -c "SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE datname = 'mockupaws';"
+
+# 2. Restore from latest backup
+./scripts/restore.sh latest
+
+# 3. Verify data integrity
+./scripts/verify-data.sh
+
+# 4. Resume application traffic
+```
+
+#### Scenario 2: Complete Region Failure
+
+```bash
+# 1. Activate DR region
+export BACKUP_BUCKET="mockupaws-backups-dr"
+export AWS_REGION="eu-west-1"
+
+# 2. Restore to DR database
+./scripts/restore.sh latest
+
+# 3. Update DNS/application configuration
+# Point to DR region database endpoint
+
+# 4. Verify application functionality
+```
+
+#### Scenario 3: Accidental Data Deletion
+
+```bash
+# 1. Identify deletion timestamp (from logs)
+DELETION_TIME="2026-04-07 15:23:00"
+
+# 2. Restore to point just before deletion
+./scripts/restore.sh latest --target-time "$DELETION_TIME"
+
+# 3. Export missing data
+pg_dump --data-only --table=deleted_table > missing_data.sql
+
+# 4. Restore to current and import missing data
+```
+
+### DR Testing Schedule
+
+| Test Type | Frequency | Responsible |
+|-----------|-----------|-------------|
+| Backup verification | Daily | Automated |
+| Restore test (dev) | Weekly | DevOps |
+| Full DR drill | Monthly | SRE Team |
+| Cross-region failover | Quarterly | Platform Team |
+
+---
+
+## Monitoring & Alerting
+
+### Backup Monitoring
+
+```sql
+-- Check backup history
+SELECT 
+    backup_type,
+    created_at,
+    status,
+    EXTRACT(EPOCH FROM (NOW() - created_at))/3600 as hours_since_backup
+FROM backup_history 
+ORDER BY created_at DESC 
+LIMIT 10;
+```
+
+### Prometheus Alerts
+
+```yaml
+# backup-alerts.yml
+groups:
+  - name: backup_alerts
+    rules:
+      - alert: BackupNotRun
+        expr: time() - max(backup_last_success_timestamp) > 90000
+        for: 1h
+        labels:
+          severity: critical
+        annotations:
+          summary: "Database backup has not run in 25 hours"
+          
+      - alert: BackupFailed
+        expr: increase(backup_failures_total[1h]) > 0
+        for: 5m
+        labels:
+          severity: warning
+        annotations:
+          summary: "Database backup failed"
+          
+      - alert: LowBackupStorage
+        expr: s3_bucket_free_bytes / s3_bucket_total_bytes < 0.1
+        for: 1h
+        labels:
+          severity: warning
+        annotations:
+          summary: "Backup storage capacity < 10%"
+```
+
+### Health Checks
+
+```bash
+# Check backup status
+curl -f http://localhost:8000/health/backup || echo "Backup check failed"
+
+# Check WAL archiving
+psql -c "SELECT archived_count, failed_count FROM pg_stat_archiver;"
+
+# Check replication lag (if applicable)
+psql -c "SELECT EXTRACT(EPOCH FROM (now() - pg_last_xact_replay_timestamp())) AS lag_seconds;"
+```
+
+---
+
+## Troubleshooting
+
+### Common Issues
+
+#### Issue: Backup fails with "disk full"
+
+```bash
+# Check disk space
+df -h
+
+# Clean old backups
+./scripts/backup.sh cleanup
+
+# Or manually remove old local backups
+find /path/to/backups -mtime +7 -delete
+```
+
+#### Issue: Decryption fails
+
+```bash
+# Verify encryption key matches
+export BACKUP_ENCRYPTION_KEY="correct-key"
+
+# Test decryption
+openssl enc -aes-256-cbc -d -pbkdf2 -in backup.enc -out backup.sql -pass pass:"$BACKUP_ENCRYPTION_KEY"
+```
+
+#### Issue: Restore fails with "database in use"
+
+```bash
+# Terminate connections
+psql -c "SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE datname = 'mockupaws' AND pid <> pg_backend_pid();"
+
+# Retry restore
+./scripts/restore.sh latest
+```
+
+#### Issue: S3 upload fails
+
+```bash
+# Check AWS credentials
+aws sts get-caller-identity
+
+# Test S3 access
+aws s3 ls s3://$BACKUP_BUCKET/
+
+# Check bucket permissions
+aws s3api get-bucket-acl --bucket $BACKUP_BUCKET
+```

+## Overview
+
+As mockupAWS accumulates data over time, we implement an automated archiving strategy to:
+
+- **Reduce storage costs** by moving old data to archive tables
+- **Improve query performance** on active data
+- **Maintain data accessibility** through unified views
+- **Comply with data retention policies**
+
+### Archive Strategy Overview

+
+#### Unified Views (Query Transparency)
+
+```sql

+    true as is_archived
+FROM scenario_metrics_archive;
+```
+
+### Archive Job Tracking
+
+```sql
+-- Archive jobs table
+CREATE TABLE archive_jobs (
+    id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
+    job_type VARCHAR(50) NOT NULL,
+    status VARCHAR(50) NOT NULL DEFAULT 'pending',

+FROM reports_archive;
+```
+

+
+## Archive Job
+
+### Running the Archive Job
+
+```bash
+# Preview what would be archived (dry run)
+python scripts/archive_job.py --dry-run --all
+
+# Archive all eligible data
+python scripts/archive_job.py --all
+
+# Archive specific types only
+python scripts/archive_job.py --logs
+python scripts/archive_job.py --metrics
+python scripts/archive_job.py --reports
+
+# Combine options
+python scripts/archive_job.py --logs --metrics --dry-run
+```
+
+### Cron Configuration
+
+```bash
+# Run archive job nightly at 3:00 AM
+0 3 * * * /opt/mockupaws/.venv/bin/python /opt/mockupaws/scripts/archive_job.py --all >> /var/log/mockupaws/archive.log 2>&1
+```
+
+### Environment Variables
+
+```bash
+# Required
+export DATABASE_URL="postgresql+asyncpg://user:pass@host:5432/mockupaws"
+
+# For reports S3 archiving
+export REPORTS_ARCHIVE_BUCKET="mockupaws-reports-archive"
+export AWS_ACCESS_KEY_ID="your-key"
+export AWS_SECRET_ACCESS_KEY="your-secret"
+export AWS_DEFAULT_REGION="us-east-1"
+```
+
+---
+
+## Querying Archived Data
+
+### Transparent Access
+
+Use the unified views for automatic access to both live and archived data:
+
+```sql
+-- Query all logs (live + archived)
+SELECT * FROM v_scenario_logs_all 
+WHERE scenario_id = 'uuid-here'
+ORDER BY received_at DESC
+LIMIT 1000;
+
+-- Query all metrics (live + archived)
+SELECT * FROM v_scenario_metrics_all 
+WHERE scenario_id = 'uuid-here'
+  AND timestamp > NOW() - INTERVAL '2 years'
+ORDER BY timestamp;
+```
+
+### Optimized Queries
+
+```sql
+-- Query only live data (faster)
+SELECT * FROM scenario_logs 
+WHERE scenario_id = 'uuid-here'
+ORDER BY received_at DESC;
+
+-- Query only archived data
+SELECT * FROM scenario_logs_archive 
+WHERE scenario_id = 'uuid-here'
+  AND received_at < NOW() - INTERVAL '1 year'
+ORDER BY received_at DESC;
+
+-- Query specific month partition (most efficient)
+SELECT * FROM scenario_logs_archive 
+WHERE received_at >= '2025-01-01' 
+  AND received_at < '2025-02-01'
+  AND scenario_id = 'uuid-here';
+```
+
+### Application Code Example
+
+```python
+from sqlalchemy import select
+from src.models.scenario_log import ScenarioLog
+
+async def get_logs(db: AsyncSession, scenario_id: UUID, include_archived: bool = False):
+    """Get scenario logs with optional archive inclusion."""
+    
+    if include_archived:
+        # Use unified view for complete history
+        result = await db.execute(
+            text("""
+                SELECT * FROM v_scenario_logs_all 
+                WHERE scenario_id = :sid
+                ORDER BY received_at DESC
+            """),
+            {"sid": scenario_id}
+        )
+    else:
+        # Query only live data (faster)
+        result = await db.execute(
+            select(ScenarioLog)
+            .where(ScenarioLog.scenario_id == scenario_id)
+            .order_by(ScenarioLog.received_at.desc())
+        )
+    
+    return result.scalars().all()
+```
+
+---
+
+## Monitoring
+
+### Archive Job Status
+
+```sql
+-- Check recent archive jobs
+SELECT 
+    job_type,
+    status,
+    started_at,
+    completed_at,
+    records_archived,
+    records_deleted,
+    pg_size_pretty(bytes_archived) as space_saved
+FROM archive_jobs
+ORDER BY started_at DESC
+LIMIT 10;
+
+-- Check for failed jobs
+SELECT * FROM archive_jobs 
+WHERE status = 'failed'
+ORDER BY started_at DESC;
+```
+
+### Archive Statistics
+
+```sql
+-- View archive statistics
+SELECT * FROM v_archive_statistics;
+
+-- Archive growth over time
+SELECT 
+    DATE_TRUNC('month', archived_at) as archive_month,
+    archive_type,
+    COUNT(*) as records_archived,
+    pg_size_pretty(SUM(total_bytes)) as bytes_archived
+FROM v_archive_statistics
+GROUP BY DATE_TRUNC('month', archived_at), archive_type
+ORDER BY archive_month DESC;
+```
+
+### Alerts
+
+```yaml
+# archive-alerts.yml
+groups:
+  - name: archive_alerts
+    rules:
+      - alert: ArchiveJobFailed
+        expr: increase(archive_job_failures_total[1h]) > 0

+
+## Storage Estimation
+
+### Projected Storage Savings
+
+Assuming typical usage patterns:
+
+| Data Type | Daily Volume | Annual Volume | After Archive | Savings |
+|-----------|--------------|---------------|---------------|---------|
+| Logs | 1M records/day | 365M records | 365M in archive | 0 in main |
+| Metrics | 500K records/day | 182M records | 60M aggregated | 66% reduction |
+| Reports | 100/day (50MB each) | 1.8TB | 1.8TB in S3 | 100% local reduction |
+
+### Cost Analysis (Monthly)
+
+| Storage Type | Before Archive | After Archive | Monthly Savings |
+|--------------|----------------|---------------|-----------------|
+| PostgreSQL (hot) | $200 | $50 | $150 |
+| PostgreSQL (archive) | $0 | $30 | -$30 |
+| S3 Standard | $0 | $20 | -$20 |
+| S3 Glacier | $0 | $5 | -$5 |
+| **Total** | **$200** | **$105** | **$95** |
+
+*Estimates based on AWS us-east-1 pricing, actual costs may vary.*
+
+---
+
+## Maintenance
+
+### Monthly Tasks
+
+1. **Review archive statistics**
+   ```sql
+   SELECT * FROM v_archive_statistics;
+   ```
+
+2. **Check for old archive partitions**
+   ```sql
+   SELECT 
+       schemaname, 
+       tablename,
+       pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename)) as size
+   FROM pg_tables
+   WHERE tablename LIKE 'scenario_logs_archive_%'
+   ORDER BY tablename;
+   ```
+
+3. **Clean up old S3 files** (after retention period)
+   ```bash
+   aws s3 rm s3://mockupaws-reports-archive/archived-reports/ \
+     --recursive \
+     --exclude '*' \
+     --include '*2023*'
+   ```
+
+### Quarterly Tasks
+
+1. **Archive job performance review**
+   - Check execution times
+   - Optimize batch sizes if needed
+
+2. **Storage cost review**
+   - Verify S3 lifecycle policies
+   - Consider Glacier transition for old archives
+
+3. **Data retention compliance**
+   - Verify deletion of data past retention period
+   - Update policies as needed
+
+---
+
+## Troubleshooting
+
+### Archive Job Fails
+
+```bash
+# Check logs
+tail -f storage/logs/archive_*.log
+
+# Run with verbose output
+python scripts/archive_job.py --all --verbose
+
+# Check database connectivity
+psql $DATABASE_URL -c "SELECT COUNT(*) FROM archive_jobs;"
+```
+
+### S3 Upload Fails
+
+```bash
+# Verify AWS credentials
+aws sts get-caller-identity
+
+# Test S3 access
+aws s3 ls s3://mockupaws-reports-archive/
+
+# Check bucket policy
+aws s3api get-bucket-policy --bucket mockupaws-reports-archive
+```
+
+### Query Performance Issues
+
+```sql
+-- Check if indexes exist on archive tables
+SELECT indexname, indexdef 
+FROM pg_indexes 
+WHERE tablename LIKE '%_archive%';
+
+-- Analyze archive tables
+ANALYZE scenario_logs_archive;
+ANALYZE scenario_metrics_archive;
+
+-- Check partition pruning
+EXPLAIN ANALYZE 
+SELECT * FROM scenario_logs_archive 
+WHERE received_at >= '2025-01-01' 
+  AND received_at < '2025-02-01';
+```

+
+## Monitoring & Alerting
+
+### Key Metrics to Monitor
+
+```sql
+-- Query performance (should be < 200ms p95)
+SELECT query_hash, avg_execution_time 
+FROM query_performance_log 
+WHERE execution_time_ms > 200
+ORDER BY created_at DESC;
+
+-- Archive job status
+SELECT job_type, status, records_archived, completed_at
+FROM archive_jobs
+ORDER BY started_at DESC;
+
+-- PgBouncer stats
+SHOW STATS;
+SHOW POOLS;
+
+-- Backup history
+SELECT * FROM backup_history 
+ORDER BY created_at DESC 
+LIMIT 5;
+```
+
+### Prometheus Alerts
+
+```yaml
+alerts:
+  - name: SlowQuery
+    condition: query_p95_latency > 200ms
+    
+  - name: ArchiveJobFailed
+    condition: archive_job_status == 'failed'
+    
+  - name: BackupStale
+    condition: time_since_last_backup > 25h
+    
+  - name: PgBouncerConnectionsHigh
+    condition: pgbouncer_active_connections > 800
+```
+
+---
+
+## Support & Troubleshooting
+
+### Common Issues
+
+1. **Migration fails**
+   ```bash
+   alembic downgrade -1
+   # Fix issue, then
+   alembic upgrade head
+   ```
+
+2. **Backup script fails**
+   ```bash
+   # Check environment variables
+   env | grep -E "(DATABASE_URL|BACKUP|AWS)"
+   
+   # Test manually
+   ./scripts/backup.sh full
+   ```
+
+3. **Archive job slow**
+   ```bash
+   # Reduce batch size
+   # Edit ARCHIVE_CONFIG in scripts/archive_job.py
+   ```
+
+4. **PgBouncer connection issues**
+   ```bash
+   # Check PgBouncer logs
+   docker logs pgbouncer
+   
+   # Verify userlist
+   cat config/pgbouncer_userlist.txt
+   ```
+
+---
+
+## Next Steps
+
+1. **Immediate (Week 1)**
+   - Deploy migrations to production
+   - Configure PgBouncer
+   - Schedule first backup
+   - Run initial archive job
+
+2. **Short-term (Week 2-4)**
+   - Monitor performance improvements
+   - Tune index usage based on pg_stat_statements
+   - Verify backup/restore procedures
+   - Document operational procedures
+
+3. **Long-term (Month 2+)**
+   - Implement automated DR testing
+   - Optimize archive schedules
+   - Review and adjust retention policies
+   - Capacity planning based on growth

+```
+
+#### HashiCorp Vault (Alternative)
+
+```bash
+# Store secrets
+vault kv put secret/mockupaws/production \
+  database_url="postgresql://..." \
+  jwt_secret="xxx"
+
+# Retrieve
+vault kv get secret/mockupaws/production
+```
+
+---
+
+## Security Considerations
+
+### Production Security Checklist
+
+- [ ] All secrets stored in AWS Secrets Manager / Vault
+- [ ] Database encryption at rest enabled
+- [ ] SSL/TLS certificates valid and auto-renewing
+- [ ] Security groups restrict access to necessary ports only
+- [ ] WAF rules configured (SQL injection, XSS protection)
+- [ ] DDoS protection enabled (AWS Shield)
+- [ ] Regular security audits scheduled
+- [ ] Penetration testing completed
+
+### Network Security
+
+```yaml
+# Security Group Rules
+Inbound:
+  - Port 443 (HTTPS) from 0.0.0.0/0
+  - Port 80 (HTTP) from 0.0.0.0/0  # Redirects to HTTPS
+  
+Internal:
+  - Port 5432 (PostgreSQL) from ECS tasks only
+  - Port 6379 (Redis) from ECS tasks only
+  
+Outbound:
+  - All traffic allowed (for AWS API access)
+```
+
+---
+
+## Troubleshooting
+
+### Common Issues
+
+#### Database Connection Failed
+
+```bash
+# Check RDS security group
+aws ec2 describe-security-groups --group-ids sg-xxx
+
+# Test connection from ECS task
+aws ecs execute-command \
+  --cluster mockupaws \
+  --task task-id \
+  --container backend \
+  --interactive \
+  --command "pg_isready -h rds-endpoint"
+```
+
+#### High Memory Usage
+
+```bash
+# Check container metrics
+aws cloudwatch get-metric-statistics \
+  --namespace AWS/ECS \
+  --metric-name MemoryUtilization \
+  --dimensions Name=ClusterName,Value=mockupaws \
+  --start-time 2026-04-07T00:00:00Z \
+  --end-time 2026-04-07T23:59:59Z \
+  --period 3600 \
+  --statistics Average
+```
+
+#### SSL Certificate Issues
+
+```bash
+# Verify certificate
+openssl s_client -connect yourdomain.com:443 -servername yourdomain.com
+
+# Check certificate expiration
+echo | openssl s_client -servername yourdomain.com -connect yourdomain.com:443 2>/dev/null | openssl x509 -noout -dates
+```
+
+---
+
+## Rollback Procedures
+
+### Quick Rollback (ECS)
+
+```bash
+# Rollback to previous task definition
+aws ecs update-service \
+  --cluster mockupaws-production \
+  --service backend \
+  --task-definition mockupaws-backend:PREVIOUS_REVISION \
+  --force-new-deployment
+
+# Monitor rollback
+aws ecs wait services-stable \
+  --cluster mockupaws-production \
+  --services backend
+```
+
+### Database Rollback
+
+```bash
+# Restore from snapshot
+aws rds restore-db-instance-from-db-snapshot \
+  --db-instance-identifier mockupaws-restored \
+  --db-snapshot-identifier mockupaws-snapshot-2026-04-07
+
+# Update application to use restored database
+aws ecs update-service \
+  --cluster mockupaws-production \
+  --service backend \
+  --force-new-deployment
+```
+
+### Emergency Rollback Script
+
+```bash
+#!/bin/bash
+# scripts/deployment/rollback.sh
+
+ENVIRONMENT=$1
+REVISION=$2
+
+echo "Rolling back $ENVIRONMENT to revision $REVISION..."
+
+# Update ECS service
+aws ecs update-service \
+  --cluster mockupaws-$ENVIRONMENT \
+  --service backend \
+  --task-definition mockupaws-backend:$REVISION \
+  --force-new-deployment
+
+# Wait for stabilization
+aws ecs wait services-stable \
+  --cluster mockupaws-$ENVIRONMENT \
+  --services backend
+
+echo "Rollback complete!"
+```

+### 1.4 API Security Review
+
+#### Rate Limiting Configuration
+
+| Endpoint Category | Current Limit | Recommended | Implementation |
+|-------------------|---------------|-------------|----------------|
+| Authentication | 5/min | 5/min | Redis-backed |
+| API Key Mgmt | 10/min | 10/min | Redis-backed |
+| General API | 100/min | 100/min | Redis-backed |
+| Ingest | 1000/min | 1000/min | Redis-backed |
+| Reports | 10/min | 10/min | Redis-backed |
+
+#### Rate Limiting Test Cases
+
+```python
+# Test rate limiting effectiveness
+import asyncio
+import httpx
+
+async def test_rate_limit(endpoint: str, requests: int, expected_limit: int):
+    """Verify rate limiting is enforced."""
+    async with httpx.AsyncClient() as client:
+        tasks = [client.get(endpoint) for _ in range(requests)]
+        responses = await asyncio.gather(*tasks, return_exceptions=True)
+        
+    rate_limited = sum(1 for r in responses if r.status_code == 429)
+    success = sum(1 for r in responses if r.status_code == 200)
+    
+    assert success <= expected_limit, f"Expected max {expected_limit} success, got {success}"
+    assert rate_limited > 0, "Expected some rate limited requests"
+```
+
+#### Authentication Security
+
+| Check | Method | Expected Result |
+|-------|--------|-----------------|
+| JWT without signature fails | Unit Test | 401 Unauthorized |
+| JWT with wrong secret fails | Unit Test | 401 Unauthorized |
+| Expired JWT fails | Unit Test | 401 Unauthorized |
+| Token type confusion fails | Unit Test | 401 Unauthorized |
+| Refresh token reuse detection | Pen Test | Old tokens invalidated |
+| API key prefix validation | Unit Test | Fast rejection |
+| API key rate limit per key | Load Test | Enforced |
+

+
+### 1.5 Data Encryption Requirements
+
+#### Encryption in Transit
+
+| Protocol | Minimum Version | Configuration |
+|----------|-----------------|---------------|
+| TLS | 1.3 | `ssl_protocols TLSv1.3;` |
+| HTTPS | HSTS | `max-age=31536000; includeSubDomains` |
+| Database | SSL | `sslmode=require` |
+| Redis | TLS | `tls-port 6380` |
+
+#### Encryption at Rest
+
+| Data Store | Encryption Method | Key Management |
+|------------|-------------------|----------------|
+| PostgreSQL | AWS RDS TDE | AWS KMS |
+| S3 Buckets | AES-256 | AWS S3-Managed |
+| EBS Volumes | AWS EBS Encryption | AWS KMS |
+| Backups | GPG + AES-256 | Offline HSM |
+| Application Logs | None required | N/A |

+#### Critical Path Gaps
+
+| Module | Current | Target | Missing Tests |
+|--------|---------|--------|---------------|
+| `auth_service.py` | 35% | 90% | Token refresh, password reset |
+| `ingest_service.py` | 40% | 85% | Concurrent ingestion, error handling |

+### 3.1 Architectural Issues
+
+#### Service Layer Concerns
+
+```python

+
+#### Repository Pattern Issues
+
+```python

+
+### 3.2 Configuration Management
+
+#### Current Issues
+
+```python

+## Appendix B: Architecture Decision Records (Template)
+
+### ADR-001: Repository Pattern Implementation
+
+**Status:** Accepted  
+**Date:** 2026-04-07
+
+#### Context
+Need for consistent data access patterns across the application.
+
+#### Decision
+Implement Generic Repository pattern with SQLAlchemy 2.0 async support.
+
+#### Consequences
+- **Positive:** Consistent API, testable, DRY
+- **Negative:** Some loss of type safety with **filters
+- **Mitigation:** Create typed filters per repository
+
+#### Alternatives
+- **Active Record:** Rejected - too much responsibility in models
+- **Query Objects:** Rejected - more complex for current needs

+## Quick Start
+
+### 1. Deploy Production Infrastructure (AWS)
+
+```bash
+# Navigate to production environment
+cd terraform/environments/prod
+
+# Create terraform.tfvars
+cat > terraform.tfvars <<EOF
+environment = "production"
+region = "us-east-1"
+domain_name = "mockupaws.com"
+certificate_arn = "arn:aws:acm:..."
+ecr_repository_url = "123456789012.dkr.ecr.us-east-1.amazonaws.com/mockupaws"
+alert_email = "ops@mockupaws.com"
+EOF
+
+# Initialize and deploy
+terraform init
+terraform plan
+terraform apply
+```
+
+### 2. Configure Server (Docker Compose)
+
+```bash
+# Run Ansible playbook
+ansible-playbook -i ansible/inventory/production ansible/playbooks/setup-server.yml
+```
