REL 1. How are you managing AWS Service Limits for your account?
AWS accounts are provisioned with default service limits to prevent new users from accidentally provisioning more resources than they need. AWS customers should evaluate their AWS service needs and request appropriate changes to their limits for each region used.
Best practices:
 Monitor and manage limits Evaluate your potential usage on AWS, increase your regional limits appropriately, and allow planned growth in usage.
 Set up automated monitoring Implement tools, e.g., SDKs, to alert you when thresholds are being approached.
 Be aware of fixed service limits Be aware of unchangeable service limits and architected around these.
