Therefore, the wide scale adoption of this emerging computing paradigm is highly dependent on overcoming these challenges. In fact, the lack of bandwidth guarantees extends the completion time for jobs, thus increasing cloud clients expenses, who pay based on their use. In addition, outages in cloud data centers may result in severe revenue losses for both cloud operators and their clients alike. Now, to mitigate these challenges, cloud operators should be empowered with a strategic protection plan able to guarantee resilient and predictable performance for applications. Such a plan consists of provisioning additional backup resources (e.g. virtual machines, bandwidth) while ensuring efficient network bandwidth utilization. In this work, we exploit several bandwidth sharing opportunities in multi-tenant cloud networks while offering resilient and bandwidth guaranteed services. In contrast to previous works which target cloud clients satisfaction, we focus on optimizing network bandwidth utilization in order to increase the cloud operators' revenues while maintaining such bandwidth allocation transparent to the clients. Through several motivational examples, we highlight the sharing opportunities and show that they are able to increase cloud operators revenue while providing up to 50% of bandwidth gain in the network.
