At an elementary level, IT is all about using technology to enable the business. This really hasn’t changed, even back in the early days when IT was called data processing or management information systems.

Organizations are abandoning the costs and constraints of on-site IT systems as they move applications and systems to the cloud. Mobile devices are becoming the primary compute platform for users, automating business processes and changing application development.
