Public cloud providers do not do everything for you as it may seem. You still have plenty of responsibility set aside, and the complexity of the hybrid environment you are building makes your role even more important.

Quickly you will realize there is the need for a service integrator, somebody that overlooks all aspects of the delivery of the service to your users and customers. Whether you do this yourself or use a third party in that role is your decision, but to be successful in the hybrid cloud, you will need to make sure all aspects are addressed. Are you ready to do so?
