The ever-increasing complexity of computing systems has been accompanied by an increase in the complexity of their management. Contributing factors include the increasing size of individual networks and the dramatic growth of the Internet, the increasing heterogeneity of software and hardware components, the deployment of new networking technologies, the need for mobile access to enterprise data, and the emergence of pervasive computing. In this chapter, we focus on the management complexity resulting from integrating existing, heterogeneous systems to support corporate-wide, as well as Internet-wide, connectivity of users, employees, and applications.
