Autonomic elasticity for cloud applications and infrastructures

Elasticity, the ability to dynamically adjust infrastructure capacity to meet variations in application demand, is perhaps the most prominent feature of clouds. This seminar will present an overview of different resource management problems related to elasticity, including how to optimize capacity allocation for applications, how cloud data center providers can overbook their infrastructures with elastic (and static) applications to maximize utilization, and techniques to gracefully handle capacity shortages that arise due application elasticity.
