Industry shifts are redefining IT at all levels. On-premise IT consumption models are shifting to cloud-based services. IT as a service (IaaS) is supplanted by applications as a service. Separate development and operations are moving toward integrated development and operations (DevOps). Device-centric management models are migrating to application-centric management.Business agility requires application agility, so IT teams need to provision applications in hours instead of months. Resources need to scale up (or down) in minutes, not hours.Traditional approaches take a siloed operational view, with no common operational model for the application, network, security, and cloud teams. A common operational model delivers application agility, simplified operations, assured performance, and scale.
