I try to stay cloud agnostic -- so for production I use VMs with decent instance storage to run the various services needed to support our product. Sprinkle in S3, Route53, VPC, etc to stitch it all together. For dev/staging, I use cheaper Linode boxes where we run all the processes on a single VM and leverage the same Route53, S3, etc services which don't really require me to run a VM on EC2.
