In the case of an MVP or a minor application, it would not be so serious, but let’s imagine it is a business-critical application that affects our business considerably if it goes down. Let’s see the different Disaster Recovery strategies using Amazon Web Services!

RPO AND RTO

When we talk about disaster recovery, we have to understand two fundamental concepts before defining the strategies:

  • RPO (Recovery Point Objective) → Maximum amount of data — as measured by time — that can be lost after a recovery from a disaster
  • RTO (Recovery Time Objective) → Metric that defines the time to recover your IT infrastructure and services following a disaster to ensure business continuity

Disaster recovery strategies can be categorized into four approaches, ranging from the low cost and low complexity of making backups to more complex procedures.
