Enterprise IT infrastructure is constantly updated annually, involving a vast and complex array of underlying hardware. A key characteristic of these devices is their tight coupling with application systems. Any hardware issues (including hardware failures, device diversion, routine maintenance, expansion and upgrades, and testing) inevitably require extensive management effort to maintain and migrate application systems and hardware, increasing operational risks and management complexity for the application systems. A systematic approach to comprehensively reduce operational risks and management complexity for hardware devices is crucial, and reducing the coupling between hardware devices and application systems is essential to achieving this goal. Private cloud solutions address the significant impact of device upgrades on application platforms. By loosely coupling hardware devices and application systems, the business system's dependence on hardware devices is minimized.
