Disaster recovery is a persistent problem in IT platforms. This problem is more crucial in cloud computing, because Cloud Service Providers (CSPs) have to provide the services to their customers even if the data center is down, due to a disaster. Many businesses rely on Disaster Recovery (DR) services to prevent either manmade or natural disasters from causing expensive service disruptions. Unfortunately, current DR services come either at very high cost, or with only weak guarantees about the amount of data lost or time required to restart operation after a failure. In this paper, the authors argue that cloud computing platforms are well suited for offering DR as a service due to their pay-as-you-go pricing model that can lower costs and their use of automated virtual platforms that can minimize the recovery time after a failure.
