问题 The AWS EC2 Security Groups documentation mentions that "Security groups for EC2-VPC have additional capabilities that aren't supported by security groups for EC2-Classic" but the Security Groups dashboard does not provide any information on the "capabilities" of attributes of Security Groups that allow me to distinguish what kind of Security Group I'm looking at or what it is attached to, so that, for example I can't figure out whether I can consolidate Security Groups and share them across

I tried to add a NAT gateway to default VPC(although I am not sure I did it correctly or not because I am new to

You can use the following formula to approximately determine the ENI requirements. Projected peak concurrent executions * (Memory in GB / 3GB) I understand the reason behind this formula.
