Presented by Majid Hajibaba

Motivations on Cloudbursting• Load Dynamics

• The computational environment must dynamically grow (or shrink)• In response to dynamic loads

• Accuracy of the Analytics• The required accuracy of risk analytics • To dynamically adapt to satisfy the accuracy requirements

• Collaboration of Different Groups• Different groups run the same app. with different dataset policies • To satisfy their SLA.

• Economics• Application tasks can have very heterogeneous and dynamic priorities.• To handle heterogeneous and dynamic prov. and sched. requirements.

• Failures• To manage failures without impacting application QoS.

CometCloud based apps• VaR

• measuring the risk level of portfolios of financial instruments• VaR calculation should be completed within the limited time• computational requirements can change significantly• autonomic cloudbursts• Workload-based policy

• Image Registration• determine the mapping between two images • for medical informatics• budget-based policy
