Self-orchestrator
Introduction
The aerOS self-orchestrator module is one of the 4 essential modules within the aerOS self-* capabilities set. Composed by a rules engine, a facts generator, a trigger and wrapped by an API, it is capable of managing facts, rules and alerts, obtaining information from the self-awareness, self-realtimeness, self-healing and self-optimisation and adaptation modules to send warnings about problems in the IE to the aerOS EAT, with the goal to improve the management and coordination of their own workloads. This improves the scalability of tasks and reduces the number of errors that occur during task execution.
