CHAPTER 1 The Evolution of the Data Center 5 These materials are © 2020 John Wiley & Sons, Inc.

Virtualization technologies, such as resource schedulers and virtual machine (VM) migrations, provide intelligent, automated placement of application workloads. This prevents resource and network-throughput contention issues and maximizes server utilization by moving virtual workloads to underutilized resources within the data center. » Supports mobility: The network link between the data center and the back office is critical, but it's not the only connection. Increasingly, an organization's customers and users rely on high-speed Internet access to reach the data center from all sorts of devices including the Internet of Things (IoT), industrial control systems (ICS), and 5G. Moving applications to the cloud enables organizations to better support their customers, as well as remote and mobile users, by placing applications and their associated data "closer" to those customers and users. » Reduces time-to-market: Dynamic provisioning of on- demand resources in the cloud reduces time-to-market by enabling new applications to be delivered more rapidly. » Promotes standardization: Virtualization technologies enable organizations to create standard server builds and easily clone standard configurations. » Increases scalability: Compute, storage, and networking resources can quickly and easily be scaled up or down to support changing business requirements, such as mergers and acquisitions, as well as cyclical business environments. The modern, hybrid cloud enables greater IT efficiency, auto- mation, and agility, supporting the delivery of new application workloads across dynamic network fabric and virtual machine infrastructure. A hybrid cloud strategy allows organizations to create the right mix of cloud and traditional IT to suit their needs.
