What is AWS Service Quotas?
AWS Service Quotas enables you to view and manage your quotas (formerly called limits) for AWS services from a central location.
Key Concepts
1. View Quotas
- See the default quotas (e.g., 5 VPCs per region) and your current applied quotas.
2. Request Increases
- Request an increase simply by entering the new value. (Replaces the old "Support Ticket" workflow for many limits).
3. CloudWatch Alarms
- Set up visual alarms to notify you when you are approaching a limit (e.g., "Alert me when I'm at 80% of my EC2 instance limit").
Exam Tips
[!IMPORTANT] "Request limit increase" or "View service quotas/limits": The answer is AWS Service Quotas.
