OptiCloud: Development of a Private Cloud Infrastructure to optimize Workload Placement using Software Defined Networks based on OpenStack

Cloud computing offers great opportunities for its adopters. But due to a lack of trust and effort in workload migration, the adoption of public cloud infrastructures is not always the preferred option for organizations. The application of a private cloud infrastructure combined with software defined networking (SDN) provides the potential to mitigate few drawbacks of public clouds. For this reason the development of an optimized private cloud infrastructure applicable particularly for small and medium enterprises is investigated. This paper provides an overview of the cloud platform used for that purpose, the cloud setup, and required optimizations needed for an effective private cloud. An optimized workload placement algorithm is introduced that combines information gathered from data available through the use of SDN.
