The enterprise IT architecture has been on a fast-paced trajectory of growth and evolution. Today, the emergence of cloud computing — computing that is based on the internet — has presented a notable and nearly ubiquitous change to the IT environment, opening up a world of new opportunity.

Furthermore, usage of this cloud is still growing. However, while the public
