Heuristics based server consolidation with residual resource defragmentation in cloud data centers
We model residual resource fragmentation in cloud data centers. We examine feasibility of residual resource defragmentation with server consolidation. Proposed approach performs defragmentation with low energy cost and SLA violations. Controlled defragmentation with consolidation reduces VM migrations. A good mix of cloud applications ensures better defragmentation.
