Formation of Dynamic Collaborative Cloud Links Based on Provider Capability Cost and Resource Health Monitoring

Abstract

Typically in collaborative cloud systems, the collaborations are formed based on pre-negotiated terms and conditions. Care is taken to ensure that the resources are planned in such a way so as to satisfy the SLA requirements. However, these static collaborations pose certain challenges in the long run, which arise due to the changes in quality of resources and provider capabilities. In such a scenario, there is a need to dynamically establish appropriate collaborations so as to back-fill the resource quality and overcome shortfalls in provider capabilities. Our paper puts forth a mathematical model for cloud provider capabilities along with an approach to establish dynamic cloud provider collaborations. In our approach, once the under functioning resource is identified, we are able to find the most suitable replacement resource from within the same cloud provider or if need be, establish a new collaboration with another provider based on the required resource capabilities. This choice for new collaboration is based on the tenancy requirements, current state of resource utilization and capacity, and health of the specific resource to be replaced. Our algorithms to determine the replacement resource and form the collaboration links are illustrated along with a running example and proof-of-concept implementation.
