Scale up at the Speed of Sound
summary
Claim: putting compiled binaries and packages directly into a custom stemcell cuts deployment time from about 4 minutes to ~1:10 on GCP and down to ~35s on a faster cluster, a ~2–6× speedup. Method: use bosh stemcell-builder rake tasks, pre-baked packages on stemcell, untar exported releases to export releases and untar packages, modify job manifests to become releases without packages, and produce new artifacts with a small tool (Project Mach). Result: it works, gives big developer-speed wins, but is manual and not yet production hardened; discovered additional wins from credhub export, caching images, and fixing flannel/docker race conditions.
