Distributed computer systems: four case studies
Article Abstract:
Four systems, representing a spectrum of decentralization, demonstrate the benefits of distributed systems architecture. Each was adopted for advantages in capacity, modular growth, availability, and price. The disaster recovery system required replication of data at two sites. A multi-site system with central control is needed to distribute processing and storage for cost reduction, and to minimize the scope of failures. The federated system with node autonomy was decentralized to reflect the organization of its users. The single site system avoided operational and organizational problems of distribution. All of the systems were built with off-the-shelf hardware and software. All were programmed in conventional Cobol.

Computer configurations
Article Abstract:
Energy Management Systems computer configuration technology is reviewed. Changes in the current hardware and software technology and changing requirements from utilities have caused a significant alteration of systems architectures. The evolution of systems is shown. Current systems have much commonality in approach. The trend for the future is for improved configurations, greater in power, but more simplistic in design and easier to maintain.
