Embodiments are directed to scaling services, transitioning from a first service version to a second version and to implementing an external system integration service. In one scenario, a computer system establishes a message broker service that maintains message queues that allow communication between services. The message queues receive messages from publishers and transfer messages to subscribers. The computer system indicates a specified message queue for each service, where the specified message queue is configured to maintain messages for that service. The computer system also moves at least one of the services to a second, different computer system, while the specified message queue maintains messages for the moved service. The computer system further allows an external system integration service to be implemented which subscribes to specified, registered messages and forwards the registered messages to selected external entities. |
