Any system that intends to be fully automated and self-sufficient must be capable of self-healing and self-adaptation. As a minimum, it needs to be able to monitor itself and perform certain actions both on service and infrastructure levels.
Two axes can represent the set of actions a system might execute. One group of actions be represented through the differences between infrastructure and services. The other axis can be explained by the type of activities, with self-healing on one end, and self-adaptation on the other.
The most common type of self-healing, when applied to infrastructure, is to recreate a failed or a faulty node. When infrastructure needs to be adapted to changed conditions, nodes are scaled. Self-healing is mostly about rescheduling failed services. When system's conditions change, it should self...
