I'm new to aws cloud service. I have to create a parallel cluster in aws. So, I'm using aws parallel cluster. But the problem is, when creating a cluster the NAT gateway billing me when I'm not using it. So, the cost increases. Is there any way I can minimize or automate the NAT gateway process so that it will cost me less??
PS:If there is any project which gives me on demand NAT gateway hour or Nat gateway instances in parallel cluster that would be very nice.
