Reorchestration: A Prototype for Reactive Orchestration

Orchestration is crucial to address the growing complexity of IT, cloud and telecom services. Orchestrators enable service deployment, but continuous operation is given second-class status. Most orchestrators use static workflows, which may fail, misbehave or be insufficient, leaving services in an undesirable state. We present Reorchestration, a prototype showing orchestration without workflows, combining functional-inspired state management with an infrastructure-as-code approach. The prototype demonstrates the viability of our ideas in some scenarios, and we expect it will contribute to discussions on software architectures for closed-loop automation.
