A Amazon observa em sua documentação sobre T2 (burstable ) instâncias de que, embora essas instâncias normalmente tenham inicialmente 30 créditos de CPU, há limites em como esse crédito inicial será aplicado.
- There are limits to how many T2 instances will launch or start with the initial CPU credit, which by default is set to 100 launches or starts of any T2 instance per account, per 24-hour period, per region. If you'd like to increase this limit, you can file a customer support limit increase request by using the Amazon EC2 Instance Request Form. If your account does not launch or start more than 100 T2 instances in 24 hours, this limit will not affect you.
