Kelvin, The problem Isaac is trying to solve is that many of our contributors don’t have enough memory or fast enough swap speeds to run the services all at once on their computers for doing development testing. Also startup speeds are very slow because some services need to be completely up and provisioned before other services can be started.
Isaac is not trying to create a production environment here. If he were, than the rate at which requests can be handled would, of course, matter. But demo-server was never intended as a production environment; correct production environment will be *highly* dependent on use case. Nonetheless I would welcome your contribution of docker specifications. I do think the docker files should go into the service repositories rather than the demo-server. There are also exciting ideas in circulation for doing this with OpenShift instead.
