Ask HN: How fast is an AWS auto scaling group?
Let's say if there is a sudden spike in traffic, and I need to go from 50 EC2 instances to 300. How long would it take (lets assume a pre-baked AMI). If every EC2 takes x minutes to start up, in how much time will my auto scaling group achieve the target size? Will all 250 instances be started up in parallel ?
