Multi-constrained multi-provider orchestration is alone challenging, which we complemented with an automated multi-layered failure recovery mechanism. Our proof of concept prototype demonstrates information models (both bottom-up and top-down), orchestration and recovery workflows with delegation, trial and error based backtracking among the chain of federated providers in an Industry 4.0 use-case for critical machine type communication (C-MTC). With a remote factory scenario, we show fault recovery from single to multi provider involvement. We provide insights into the responsibility split for failure handling between service agnostic resource orchestration and service specific lifecycle management components. |
