Abstract
The Realize middleware manages the resources of CORBA distributed systems for soft real-time applications, and replicates CORBA objects to provide high availability and fault tolerance. By measuring the usage of the resources and by monitoring the behavior of the application, Realize allocates the objects to the processors and schedules the tasks in order to balance the load and to meet soft real-time deadlines. By using totally ordered multicast messages, Realize maintains the consistency of the replicas of the objects. The difficult issues of distribution, real-time scheduling, replication, consistency, and fault detection and recovery are handled by Realize and are hidden from the application programmer.
