ECA Group OPSYS successfully runs the Virtual Application Platform (VAP) equipment developed by MicroEJ. MicroEJ enables the separation between software and hardware to simplify application software development. As a consequence, developers are focused only on the application functions design, without worrying about hardware target on which its application will run. This separation simplifies also hardware obsolescence treatment and it minimizes the T&E process. This guarantees the same functionality of the application software in case of using new hardware. This method allows cost reduction of equipment obsolescence treatment and increases its life cycle.
