Cost-effective, Autonomic and Adaptive Cloud Resource Management

Current large scale web applications pose enormous and dynamic processing and storage requirements. Failures of any type are common in current datacenters, partly due to the higher scales of the data stored. As data scales up, its availability becomes more complex, while different availability levels per application or per data item may be required. At the same time, cloud infrastructures should be able to effectively deal with the elastic nature of these applications in an autonomic manner. To make things worse, as clients get increasingly averse to vendor lock-in and data unavailability risks, client data has to be efficiently split across clouds. In this talk, we briefly discuss three very effective cloud resource management solutions that deal with the different aforementioned requirements: Skute, Scarce and Scalia. Skute is a self-managed key-value store that dynamically allocates the resources of a data cloud to several applications in a cost-efficient and fair way. Scarce is a decentralized economic approach for dynamically adapting the cloud resources of various applications, so as to statistically meet their SLA performance and availability goals in the presence of varying loads or failures. Scalia is a cloud storage brokerage solution that continuously adapts the placement of data based on its access pattern, subject to optimizations objectives and data placement constraints, such as storage costs and vendor lock-in avoidance.
