Infrastructure is a combined set of hardware, software, networks, facilities, etc. (including all of the information technology), in order to develop, test, deploy, operate, monitor, control, maintain and support the delivery of IT services.
Infrastructure Capability
The infrastructure capability is the IT capability system which functions to realize computing equipment, middleware, IT platforms (databases), IT storage, IT networks and IT security infrastructure.
The purpose of the infrastructure capability is to enable and assure the abilities of the IT infrastructure of the enterprise.
Infrastructure Management
Infrastructure management is the IT capability management of the infrastructure capability.
The purpose of infrastructure management is to enable and assure the management and abilities of the IT infrastructure capabilities of the enterprise are controlled, balanced and aligned to the mission and needs of the enterprise as a whole.
Infrastructure Management Responsibilities
The IT manager role is responsible for infrastructure management of the infrastructure capability.
Infrastructure management work products include infrastructure management ideas, requirements, plans, risks, opportunities, reviews, decisions and action items.
Infrastructure Architecture
The infrastructure architecture is the IT architecture of infrastructure management of the infrastructure capability.

The purpose of the infrastructure architecture is to provide a management structure to enable and assure the infrastructure capability of the enterprise is controlled, balanced and aligned to the mission and needs of the enterprise as a whole.
The structure includes computing equipment, middleware, platforms (databases), storage, networks and security infrastructure.
Infrastructure Architecture Responsibilities
The IT architect role is responsible for architecting the infrastructure architecture in support of the infrastructure management responsibilities of the IT manager role.
Infrastructure architecture work products include infrastructure architecture concepts, descriptions, models, views, viewpoints, specifications and analyses.
Infrastructure Team
As shown in Figure 68 – Infrastructure Team Concept, infrastructure is interconnected with and interdependent on integration, portfolio, data, configurations, records, system abilities and service abilities.
