I guess you're paying a 5x premium for Lambda in the constant usage scenario, a similar premium as on-demand vs spot instances. 4GB m6g.medium $0.0385/hour 4GB Lambda works out at $0.1920/hour It's been a while since I last used queue driven autoscaling groups, but https://aws.amazon.com/blogs/compute/scaling-your-applications-faster-with-ec2-auto-scaling-warm-pools/ https://aws.amazon.com/blogs/compute/scaling-your-applicatio... has startup time of about 4 minutes from scratch or 36s from a paused instance in a 'warm pool.' vs less than a second for Lambda in the original article. So the decision ends up coming down to responsiveness vs cost. Presumably Fargate comes somewhere in between.
