Deloitte reports that IT leaders increasingly utilize cloud strategies to address business challenges as well as build toward a next-generation IT operating model.
The company said Monday companies should develop a plan that considers the cloud compatibility of IT-supported business functions before migrating to cloud.
Ranjit Bawa, a principal for the technology strategy and architecture practice at Deloitte, recommends that the plan distinguish business functions that would benefit from a move to cloud, systems that are at risk of destabilization if moved to cloud outright and systems that require as-is operations.
He notes that organizations should also work to accommodate both the operations that simultaneously support new and legacy systems (“brownfields”) and those that operate exclusively on cloud (“greenfields”).
Bawa says they can follow either the “big bang” approach of switching from brownfield to greenfield, the “parallel” approach of running both with a move toward greenfield operations, or the parallel approach with a slower transition to greenfield.
