Coming in at No. 10 in our survey, demand for hybrid cloud integration services likely stems from a collective cloud adoption hangover among early cloud adopters.

Customers tend to consider hybrid cloud for cost savings or because it complements their business' computing needs, but they can't achieve these goals without help on the integration side. Whether that assistance is built into the original price or sold separately as professional services, businesses are increasingly looking to service providers for guidance.
