Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Maintaining high availability of IaaS services at a reasonable cost is a challenging task that received recent attention due to the growing popularity of Cloud computing as a preferred means of affordable IT outsourcing. In large data-centers faults are prone to happen and thus the only reasonable cost-effective method of providing high availability of services is an SLA aware recovery plan; that is, a mapping of the service VMs onto backup machines where they can be executed in case of a failure. The recovery process may benefit from poring on some of these machines in advance, since redeployment on pored machines is much faster. Hover, this comes with an additional maintenance cost, so the real problem is how to balance beten the expected recovery time improvement and the cost of machines activation.  model this problem as an offline optimization problem and present a bicriteria approximation algorithm for it. While this is the first performance guaranteed algorithm for this problem, it is somewhat complex to implement in practice. Thus,  further present a much simpler and practical heuristic based on a greedy approach.  evaluate the performance of this heuristic over real data-center data, and show that it performs ll in terms of scale, hierarchical faults and variant costs. Our results indicate that our scheme can reduce the overall recovery costs by 10-15% when compared to currently used approaches.  also show that fault recovery cost aware VM placement may farther help reducing the expected recovery costs, as it can reduce the backup machine activations costs.
