'''Information Technology Architecture''' or '''Technology Architecture''' is the [[process]] of development of methodical [[Information Technology (IT)|information technology]] specifications, models and guidelines, using a variety of Information Technology notations, for example [[Unified Modeling Language (UML)|UML]], within a coherent Information Technology architecture [[framework]], following formal and informal Information Technology solution, [[Enterprise Architecture|enterprise architecture (EA)]], and [[Infrastructure Architecture|infrastructure architecture]] processes. These processes have been developed in the past few decades in response to the [[requirement]] for a coherent, consistent approach to delivery of information technology capabilities. They have been developed by information technology [[product]] vendors and independent consultancies, based on real experiences in the information technology marketplace and [[collaboration]] amongst [[industry]] [[Stakeholder|stakeholders]], for example the Open Group. Best practice Information Technology architecture encourages the use of open technology standards and global technology [[interoperability]]. Information Technology (I.T) Architecture can also be called a high-level map or plan of the information assets in an [[organization]], including the physical [[design]] of the building that holds the [[hardware]].<ref>Defining Information Technology Architecture [https://en.wikipedia.org/wiki/Information_technology_architecture Wikipedia]</ref>

Technology architecture associates [[application]] components from [[Application Architecture|application architecture]] with technology components representing [[Software|software]] and [[Hardware|hardware]] components. Its components are generally acquired in the marketplace and can be assembled and configured to constitute the enterprise’s technological infrastructure. Technology architecture provides a more concrete view of the way in which application components will be realized and deployed. It enables the migration problems that can arise between the different steps of the [[Information System (IS)|IS]] evolution path to be studied earlier. It provides a more precise means of evaluating responses to constraints (nonfunctional requirements) concerning the IS, notably by estimating hardware and [[Network|network]] sizing needs or by setting up [[server]] or storage redundancy. Technology architecture concentrates on logistical and location problems related to hardware location, IS [[management]] capabilities, and the sites where the different parts of the IS are used. Technology architecture also ensures the delivered application components work together, confirming that the required [[business]] integration is supported.<ref>What is Technology Architecture [https://www.sciencedirect.com/science/article/pii/B9780124199842000100 Philippe Desfray Gilbert Raymond]</ref>
