Businesses are increasingly investing in both public and private cloud computing in an effort to scale up while protecting sensitive material.
But, as a report from BI Intelligence notes, companies can run into problems when such "hybrid cloud" systems require communication between the public and private services.
The report said that businesses tend to invest a portion of funding into public cloud systems and leave the remainder in their traditional information technology systems.
Those systems, however, operate independently from one another and are accessed separately.
Instead, BI Intelligence reports, companies should focus on developing in-house systems that feature a "network of providers than can collaborate."
Analysts expect double-digit spending increases in both public and private cloud investment in coming years, and the report noted that communication and security will be increasingly important amid the proliferation of the Internet of Things.
