The DCE can be used by system vendors, software developers, and end users. It can be used on any network hardware and transport software, including TCP/IP, OSI, and X.25. The DCE is written in standard C and uses standard operating system service interfaces like POSIX and X/Open guidelines.
DCE works internally with the client/server model and is compatible for development of applications that are structured according to this model.
For DCE, intra-cell communication is optimized and relatively secure and transparent.
When using the thread services provided by DCE, the application programmer must be aware of thread synchronization and shared data across threads.
Some usage of DCE in industry are as following:
• The Common Operating Environment. DCE has been approved by DISA (Defense Information Systems Agency) as the distributed computing technology for the Common Operating Environment (COE) (see Defense Information Infrastructure Common Operating Environment)

• The Advanced Photon Source (APS) system. This is a synchrotron radiation facility under construction at Argonne National Laboratory.

• The Alaska Synthetic Aperture Radar Facility (ASF). This is the ground station for a set of earth-observing radar spacecraft, and is one of the first NASA projects to use DCE in an operational system.

• The Deep Space Network's Communications Complexes Monitor and Control Subsystem. This project is deploying DCE for subsystem internal communications, with the expectation that DCE will eventually form the infrastructure of the entire information system.
