Enterprise and global-scale systems today might have thousands to millions of geographically distributed nodes and this number will increase over time. Managing efficiently such scattered systems becomes increasingly complex and requires powerful management capabilities. Traditional solutions to manage and control them seem to have reached their limits. In recent years, integrated management systems and services as well as autonomic systems have raised much interest in distributed systems and software engineering. This paper discusses the architectural issues facing the design of large-scale distributed management systems. Then it suggests a new flexible and scalable integrated management middleware to handle management problems in large-scale networked and heterogeneous systems.
