Increasing VPC Limits
VPC and, in fact, all AWS resources come with certain soft/hard limits so that people don't misuse or continue to spin up instances without any requirement. It also helps if your AWS server/account gets hacked and the hacker starts spinning up multiple high configuration servers to give you a billing heart attack.
