A real-world problem that occurs in data centers is the periodic performance challenges associated with enter- prise applications such as e-mail or database applica- tions. In this example, an enterprise application is performing below a minimum-acceptable performance threshold. Operational policies determine that an addi- tional server with associated storage must be config- ured and brought online to meet demand. This process can take days if performed manually, but the automated processes in the emerging data center can dramatically reduce the time.
