Infrastructure Architecture is the activity responsible for ensuring the technical systems and infrastructure are designed to support business requirements. This may include support for business strategy in the ability to scale operations across different regions, support a business drive to support mobile devices, and to ensure data security. A key outcome for a structured approach to infrastructure architecture includes well documented and integrated infrastructure models, with the correct level of detail and abstraction for different stakeholders. Additionally, understanding the interconnectedness of the technical infrastructure with the rest of the business is one of the core value propositions of infrastructure architecture. This allows infrastructure architects to get a view of the impact of change in business strategy on infrastructure requirements and, conversely, the impact on the business of any changes to the infrastructure.
