Chapter 1. Overview

Given the Metro disaster recovery stretch cluster is to provide resiliency in the face of a complete or partial site outage, it is important to understand the different methods of recovery for applications and their storage.

How the application is architected will determine how soon it can be available again on the active zone.

Depending on the site outage, there can be different methods of recovery for applications and their storage. The recovery time depends on the application architecture. The different methods of recovery are as follows:

  • Recovery for zone-aware HA applications with RWX storage
  • Recovery for HA applications with RWX storage
  • Recovery for applications with RWO storage
  • Recovery for StatefulSet pods
