I'm growing increasingly concerned about the fact that we're setting the server inter-connects at deploy time instead of run-time. It's making deploy complex, and it's really reducing the flexibility we could have with our system infrastructure. I see two alternative options: Every API command takes a "configuration" has as optional input: { workspace_url => "http//kbase.us/services/workspace" fba_url => "http//kbase.us/services/fba" etc…. } There would be a default "production" config, but this would allow users to build their own custom config for use with development servers for example. Alternative option: We have a single "configuration" store where configurations like the one above can be generated and stored behind user-specified names. Then when I call a server command, I can tell it which "configuration" I'm using. It will talk to the config store and pull the URLs out of there. Just throwing it out there… not sure if this is what we have in mind with the service registry… but it's worth thinking about. Where this becomes really important is when you're working with an outside group to build a new service that interfaces with many other services… because then you may have to coordinate multiple development servers… and it gets tough.
