This document provides a structured framework for creating, implementing, and continually refining a Disaster Recovery (DR) plan tailored to Azure Kubernetes Service (AKS). It spans eight phases, starting from problem definition, where essential services and compliance needs are pinpointed, alongside Recovery Time Objective (RTO) and Recovery Point Objective (RPO).
