DEE - Distributed Execution Environment

A Distributed Execution Environment (DEE) in the mainframe context refers to the infrastructure and mechanisms that allow z/OS systems to initiate, manage, or participate in workloads and processes that execute on non-z/OS platforms, such as Linux, Windows, or cloud environments. It enables the integration and orchestration of tasks across heterogeneous computing landscapes, often with the mainframe acting as the central point of control or a key service provider. This environment facilitates the seamless execution of business processes that span traditional mainframe applications and modern distributed components.
