Coordination-Aware Elasticity

Enabling and controlling elasticity of cloud computing applications is a challenging issue. Elasticity programming directives have been introduced to delegate elasticity control to infrastructures and to separate elasticity control from application logic. Since coordination models provide a general approach to manage interaction and elasticity control entails interactions among cloud infrastructure components, we present a coordination-based approach to elasticity control, supporting delegation and separation of concerns at design and run-time, paving the way towards coordination-aware elasticity.
