Self-healing infrastructures
Another important paradigm to adopt for cloud-native applications as it relates to scalability and availability are self-healing infrastructures. A self-healing infrastructure is an inherently smart deployment that is automated to respond to known and common failures. Depending on the failure, the architecture is inherently resilient and takes appropriate measures to remediate the error.
The self-healing aspect can apply at the application, system, and hardware levels. The cloud has completely taken responsibility for "hardware self-healing". No such thing technically exists, as we have yet to figure out a way to repair broken hard disks, torched CPUs, or to replace burned-out RAM without human interaction. As cloud consumers, however, the current state of affairs mimics an idealistic future. CSPs deploy people behind the scenes to repair and replace failing hardware resources quickly and furtively. By our strict definition, we have yet to approach self-healing...
