Product Overview

The architecture of CA DUO consists of several key components: the DUO Control Program, the DUO Execution Environment, and the DUO System Services. The DUO Control Program manages the overall operation of the emulation environment. The DUO Execution Environment provides the runtime environment for executing z/VSE programs.

The DUO System Services provide the necessary system-level functions to support the emulation. These components communicate through z/OS system calls and internal interfaces. Data storage relies on z/OS file systems and datasets.

There are no specific API endpoints. The product uses the z/OS console for administrative tasks. Security is handled through z/OS security systems, such as RACF, ACF2, or Top Secret.

The product provides an emulation layer, allowing z/VSE programs to run without modification. The main difference from competitors is the focus on runtime translation rather than code modification.
