Progressive recovery for cloud-based infrastructure services

Abstract

Cloud-based services allow users to outsource their application and infrastructure needs over external datacenter/ networking facilities. However, as these offerings gain traction, there is a pressing need to address disaster recovery concerns, particularly for (virtual network) infrastructure services. However, only a handful of studies have looked at designing robust storage/computing/networking service interconnections for such scenarios. Moreover, these efforts have primarily focused on pre-fault protection design and not post-fault recovery. Indeed, the latter concern is of critical importance since physical repairs will likely occur in a time-staged manner. Hence this paper introduces the concept of progressive recovery for cloud-based infrastructure services and presents some of the first solutions in this space. 2015 IEEE.
