Elastic DR: a solution architecture that aims to optimally balance cost and recovery time via three core principles that are germane the cloud world:
On-Demand: The disaster recovery cloud can be provisioned on any availability zone, region, or public/private cloud through Cloudify's cloud-agnostic bootstrapping mechanism.
Elastic: The ability to automatically provision resources in the recovery cloud in case of disaster while eliminating the need for idle resources in normal scenarios, thereby fully profiting from the pay-per-use pricing model of clouds.
Flexible RTO/RPO: The architecture can be easily extended from a warm DR to a hot DR pattern through enabling/disabling application recipes. This allows us to exploit economies of scale that the cloud provides by matching the number of recipes/tiers to provision (in the recovery cloud) against the recovery time/point objective for our disaster recovery strategy
