The promise of the modern data center lies in the business agility that it can facilitate. Traditionally, networking and layer 4 - 7 application services have required manual configuration and constant management to keep pace with changes in the data center. Today, organizations can more nimbly provide rapid, cloud-like services to users, customers and partners. They are also able to consolidate infrastructure components and services so that they are automated, driven by business policies and centrally managed for performance.
