Tenant Isolation Strategy

• Database Level: Row-level security with organizationId
• Application Level: Tenant context in all operations
• API Level: Tenant-specific routing and validation
• Caching Level: Tenant-isolated cache keys

Tenant Lifecycle Management

// Tenant provisioning
const tenant = await tenantService.provision({
  name: 'Acme Corp',
  plan: 'ENTERPRISE',
  features: ['advanced-analytics', 'custom-theming'],
})

// Tenant deprovisioning
await tenantService.deprovision(tenant.id, {
  transferData: true,
  targetTenantId: 'target-tenant-id',
})

🔒 SOC2 Type II Compliance

Compliance Features

• Audit Logging: All data modifications tracked with user context
• Access Controls: Role-based permissions with tenant isolation
• Data Encryption: AES-256 encryption at rest and in transit
• Change Management: Version control for all configuration changes
• Incident Response: Automated alerting and response procedures

Audit Requirements

// All database operations must include audit logging
const auditLog = await auditService.log({
  action: 'USER_UPDATE',
  entityType: 'USER',
  entityId: userId,
  userId: currentUserId,
  organizationId: tenantId,
  changes: { name: 'New Name' },
  metadata: { source: 'admin-panel' },
})

Compliance Monitoring

• Automated compliance checks run daily
• Security assessments performed quarterly
• Penetration testing conducted annually
• Audit reports generated monthly

📊 Performance & Scaling

Performance Requirements

• API Response Time: < 200ms (p95)
• Database Query Time: < 100ms for tenant queries
• Concurrent Tenants: 10,000+ active tenants
• Resource Utilization: < 70% at peak load
• Uptime: 99.9% SLA with automated failover

Scaling Strategies

# Horizontal scaling configuration
services:
  backend:
    deploy:
      replicas: 3
      update_config:
        parallelism: 1
        delay: 10s
      restart_policy:
        condition: on-failure
        delay: 5s
        max_attempts: 3

Database Optimization

• Connection Pooling: PgBouncer with 100-400 connections
• Query Optimization: Intelligent indexing and caching
• Read Replicas: Automatic read scaling
• Sharding: Tenant-based sharding for 100k+ tenants

Caching Strategy

// Multi-level caching
const cache = {
  // Level 1: Memory cache (fastest)
  memory: new Map(),

  // Level 2: Redis cache (distributed)
  redis: redisClient,

  // Level 3: CDN cache (global)
  cdn: cdnClient,
}

// Cache-aside pattern
const getUser = async (userId: string) => {
  // Check memory cache first
  if (cache.memory.has(userId)) {
    return cache.memory.get(userId)
  }

  // Check Redis cache
  const cached = await cache.redis.get(`user:${userId}`)
  if (cached) {
    cache.memory.set(userId, cached)
    return cached
  }

  // Fetch from database
  const user = await db.user.findUnique({ where: { id: userId } })

  // Cache in Redis and memory
  await cache.redis.set(`user:${userId}`, user, 'EX', 3600)
  cache.memory.set(userId, user)

  return user
}
