Disaster Recovery in Cloud Computing

Read these sections to familiarize yourself with disaster recovery. Pay attention to the review of cloud computing and disaster recovery plans, and list the challenges associated with disaster recovery. Finally, compile a list of the different types of disaster recovery platforms.

Organizations that use cloud-based services can backup and store data in a virtual location. You learned that storing data in the cloud creates a faster and more agile organization. Think back to the list you made about the challenges associated with disaster recovery. Use what you learned about those challenges as you read this article and begin this next section.

Abstract

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. In the past few years, researchers have shown interest to disaster recovery using cloud computing, and a considerable amount of literature has been published in this area. However, to the best of our knowledge, there is a lack of precise survey for detailed analysis of cloud-based disaster recovery. To fill this gap, this paper provides an extensive survey of disaster recovery concepts and research in the cloud environments. We present different taxonomy of disaster recovery mechanisms, main challenges and proposed solutions. We also describe the cloud-based disaster recovery platforms and identify open issues related to disaster recovery.
