🧭 11. AWS Service Quotas
AWS Service Quotas helps you manage and monitor resource limits (quotas) across AWS services.
Every AWS account has limits — for example, the number of Lambda concurrent executions, EC2 instances, or API Gateway APIs you can run at once.
With Service Quotas, you can view, monitor, and request increases for these limits directly through the AWS Management Console.
| Feature | Description |
|---|---|
| Centralized Quota Management | View and manage all AWS service limits in one place. |
| CloudWatch Integration | Create CloudWatch Alarms to get alerts when you approach or exceed a quota. |
| Quota Increase Requests | Submit quota increase requests directly from the Service Quotas console. |
| Automatic Monitoring | Continuously monitors all AWS quotas across your account. |
⚙️ Example Use Case
| Scenario | Example |
|---|---|
| Monitoring Lambda Quotas | Set up a CloudWatch Alarm on “Lambda concurrent executions” to get notified when usage reaches, say, 80% of your quota. |
| Requesting Increase | If you consistently hit your EC2 instance limit, request a quota increase via the console. |
🪄 How It Works
- View Quotas – Navigate to Service Quotas Console → Select a service (e.g., Lambda).
- Monitor Usage – Check your current usage and quota.
- Set Alarms – Create CloudWatch Alarms for specific quota metrics.
- Request Increase – Submit a quota increase if needed.
🧠 Summary
- Every AWS service has quotas (limits).
- Use AWS Service Quotas to view, monitor, and request increases.
- Integrates with Amazon CloudWatch for alerting.
- Helps prevent service interruptions caused by hitting resource limits.
