    > The best optimization is simply shutting things off

    This is the way.

    A similar idea has been bouncing around in my mind for a while now. An ideal, turnkey system would do the following:

    - Execute via Lambda (serverless).

    - Support automated startup and shutdown of various AWS resources on a schedule influenced by specially formatted tags.

    - Enable resources to be brought back up out of schedule when demand dictates.

    - Operate as a TCP/HTTP proxy that can delay clients so that a given service can be started when it is dormant or, even better, the service isn't serverless but you want it to be. This can't work for everything, but perhaps enough things such that the need to run always on services is reduced.

    Cloud Custodian [1] can purportedly do some of this, but I've been reluctant to learn yet another YAML-based DSL to use it.

    So this is my "make things designed to be always-on serverless instead" project and the work AWS has done to make Java apps function on Lambda keeps me thinking about the potential to take things that 1) have a relatively long startup time and 2) are designed to be long running service loops, and find a way to force them into the serverless execution model.
