Widespread deployment of heterogeneous virtualized systems in cloud computing and warehouse-scale data centres, often used for business-critical applications, introduces new challenges and opportunities for technological advances and innovation. This special issue seeks experimental, experiential, and theoretical papers dealing with a variety of questions concerning innovations for resilience in modern IT systems.
This issue will present questions which include but are not limited to:
- In addition to the more traditional definitions of high availability and fault tolerance, the ability to respond robustly to a wide variety of changes has become extremely important in modern dynamic IT structures; is a new conception of resilience needed?
- Economics of resilience: How much is enough and what is it worth? Do we have adequate specification of resilience objectives to facilitate a global economic ecosystem in which workload resilience goals can be specified, bid, purchased, and measured?
- Disasters, DOS attacks, viral outbreaks, thermal issues, power outages, operator strikes, mass upgrades and maintenance actions are significant impairments to resilience; what new impairments to resilience arise in modern scale distributed data centres?
- How do distributed and cloud computing exacerbate and/or mitigate some of these impairments?
- How do we achieve economically viable (e.g., cost effective, green, efficient, easy-to-manage) geographical-scale resilience in computing?
- Complex systems management challenges: How do multiple managers and domains of ownership interact in vast-scale IT systems?
- What new techniques are needed for modelling, testing, validation of resilient systems and data centres?
- What design, analysis, validation, problem prediction, and test technologies are applicable and might be transferable from the safety-critical, manufacturing, and industrial domains to the IT domain?
- How can problem prediction and proactive avoidance be used to improve the resilience of these systems in light of the new classes of hazards that they face?
