Method of cloud system disaster recovery based on "Infrastructure as a code" concept

This paper proposes the method of cloud system disaster recovery based on Infrastructure as a Code (IaaC) concept. We used HashiCorp tool Terraform to define a sample cloud infrastructure based on the OpenStack cloud provider. Our goal is studying the process of the system disaster recovery meaning the time to up in case of failures. We show the benefit of using IaaC concept in comparison with manual actions needed to recover the system in case of complex cloud systems.
