I am manually setting up an Amazon VPC network, and have a need to create a NAT instance. Amazon has VPC specialized AMIs that come in various scales. Due to budget considerations, I am ambling towards using a micro instance of ami-vpc-nat.
I am concerned that with only 613mb, a micro instance may struggle when as more instances are put behind the NAT instance. Please, can anyone who has deployed this microinstance ami-vpc-nat (especially in production) share their thoughts on its performance and throughput.
