A big problem is that the newer stack is not homogenous - the applications deployed on Dyno have much, much bigger variability than the old "Rails/Rack only" stack of Heroku. Meanwhile GAE stack is fully controlled by Google and reuses, afaik, their impressive "google scale" toolchest that goes from replacement naming systems, through monitoring, IPC, custom load balancing etc. While F5 and similar offer nice hw for that, I'm not sure if their hw (or HAProxy's software) supports the architecture type used by Heroku (many heterogenous workers running wildly different applications with dynamic association of worker to machine etc.) |
