Congratulations you are now part of an every-day growing community of organizations who have moved to the Cloud! As most of your pairs, I guess you moved some aspects of your environment into the cloud, while keeping either part of all your implementation in-house.
In one hand, this is the best of both worlds, customers can leverage the benefits of the cloud, while maintaining critical users on-premises. Here we are in the Hybrid Cloud Wonderland. On the other hand, it is also the most challenging, as people count on you to deliver services and keep them running optimally in BOTH configurations.
