Enterprise architecture transformation is essential for businesses to reduce costs and increase agility. The current state of most enterprise IT architectures, with hundreds of isolated applications integrated through APIs, leads to high costs, low business agility, and difficulties changing or exiting legacy systems. Computer science provides the solution of enterprise service-oriented architecture (ESOA) which standardizes integration and allows reusable components. The ESOA Framework (ESOAFTM) is a reference architecture that guides enterprises along a gradual transition from their current application-centric "Legacy Enterprise" state to the desired fully ESOA-based "Elegant Enterprise" state. This transformation is expected to reduce total cost of ownership by 30% within a year.
