Cloud repatriation rescues CIOs
The public cloud offers the potential for better business agility, but offloading critical computing resources has a darker side. Some IT leaders are learning that running certain applications in a public cloud can cost more than doing so on-premises, leading them to rethink their strategies to instead bring those apps back in house.

Naik quickly realized the benefits of elastic computing for business apps when he migrated to Amazon Web Services (AWS), part of a global plan to consolidate from four data centers to one. But Naik also rolled back a big data system from AWS when he realized that the troves of data it generated, coupled with the high bandwidth required to move the data, would cost a lot more than it would to run the system in his own data center.
