Abstract
Cloud computing represents a shift to a more user-centered computing model where a layer of services sitting on an infrastructure decouples core business functions from the delivery of the underlying technology. IBM® recognizes that multiple ways exist to deliver IT capabilities, which include traditional software, hardware, and networking approaches, pre-integrated systems and appliances, and new breakthroughs that are provided as a service. This IBM Redbooks® Solution Guide offers more information.

Cloud computing represents a shift to a more user-centered computing model where a layer of services sitting on an infrastructure decouples core business functions from the delivery of the underlying technology. IBM® recognizes that multiple ways exist to deliver IT capabilities, which include traditional software, hardware, and networking approaches, pre-integrated systems and appliances, and new breakthroughs that are provided as a service. This IBM Redbooks® Solution Guide offers more information. The IBM z13™ is based on a heterogeneous infrastructure, with end-to-end management capabilities for flexible delivery of high value services. Because of this, it is ideal for meeting the requirements of the IBM Cloud Computing Reference Architecture (CCRA). IBM CCRA (Figure 1) defines fundamental architectural elements which constitute a cloud computing environment. The requirement is for all these infrastructure components to be managed from a single, central Common Cloud Management Platform and be able to place instances of each cloud service on the corresponding infrastructure.

Did you know?
The transformation to cloud computing quickened the adaptation of its key enabling technologies, such as virtualization. For clients looking to lower costs, perhaps by deferring capital expenditures or off-loading non-core IT processes, cloud computing presents a way to do so while still providing services and deploying them quickly. Cloud computing is becoming more widely used as technologies, such as virtualization, automation, and provisioning, mature. Because IBM z13, with its “shared everything infrastructure,” offers a fully virtualized system, integrating a cloud computing deployment as part of the existing IT optimization strategy and roadmap becomes easier.
The key benefits that are provided through cloud computing are virtualization, standardization and automation.
