Abstract:Many cloud-based applications are being hosted at external datacenter sites with abundant storage and computing resources. These setups provide many saliencies, such as high cost efficiency and rapid scalability, and are seeing strong traction today. However, as user demands continue to grow, there is a further need to deploy such applications across multiple datacenter sites to achieve improved responsiveness. As a result, many network operators are using underlying network virtualization techniques to build customized distributed storage/computing configurations for their customer needs, e.g., infrastructure as a service (IaaS) offerings. Nevertheless, as more businesses migrate to the cloud, survivability and continuity concerns are coming to the fore. Of particular concern are large-scale disaster events which can cause multiple correlated datacenter and network system outages, e.g., such as natural disasters, malicious weapons of mass destruction (WMD) attacks, cascading power outages, etc. Clearly, localized intra-site server recovery schemes will not suffice here, and instead more capable network-based strategies are needed. Hence this talk will address this challenging problem space and review a range of disaster recovery solutions for networked cloud cyberinfrastructures. Foremost, various pre-fault protection strategies will be presented to mitigate the impact of potential future disaster occurrences. However, since it is very difficult (impossible) to pre-protect against all randomized faults, further post-fault restoration strategies will also be covered. These solutions include rapid re-mapping schemes as well as more time-staged progressive infrastructure repair/recovery methodologies. The talk will conclude with some discussions on future research directions in this overall area.
