CHAPTER 5: IT INFRASTRUCTURE AND EMERGING TECHNOLOGIES
(1) IT INFRASTRUCTURE (196-198)
An IT infrastructure consists of a set of physical devices and software applications that are required to operate the entire enterprise
But IT infrastructure also includes a set of firmwide services budgeted by management and composed of both human and technical capabilities.
These services include the
following:
Computing platforms used to provide computing services
Telecommunications services
Data management services
Application software services
Physical facilities management services
IT management services
IT standards services
IT education services
IT research and development services
This “service platform” perspective makes it easier to understand the business value provided by infrastructure investments.
