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.

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.
- Higher utilization
- Economy-of-scale benefits
- Lower capital expense
- Lower operating expense
- Easier access
- Flexible pricing
- Reuse and sharing
- Easier integration
- Faster cycle times
- Lower support costs
- Optimized utilization
- Improved compliance
- Optimized security
- Better user experience
Cloud computing on IBM z13 builds on the industry’s leading virtualization technology that uses virtualization, standardization, and automation to free the operational budget for new investments. This technology also allows you to optimize new investments for direct business benefits. The IBM z13 provides the following features:
- A highly scalable heterogeneous pool of virtualized resources that are managed in a single system
- On-demand activation, allocation, prioritization, and retiring of resources, and automation of service delivery
- Maximized utilization of resources for improved return on investment (ROI) and lower cost of service delivery
- Increased levels of security, resiliency, and manageability to create a cloud environment that is enterprise-ready
- More processing capacity, multithreading, and larger memory to consolidate different applications with less physical infrastructure
IBM z13, as the IT industry’s first multi-architecture cloud solution, provides these benefits:
- Higher utilization:
– Up to 100% CPU utilization
– Shared everything architecture
– Hosting of thousands of mixed workloads
– Multithreading capability
- Increased productivity:
– Single point of control for a heterogeneous infrastructure at a platform level, with Unified Resource Manager
– Efficient, rapid provisioning
– Superior workload management that is enabled with Unified Resource Manager
– Workload optimization with fit-for-purpose approach
– Collocating applications where industry-leading IBM z/OS® transaction and data services run
- More efficient data center:
– Less power and cooling
– Less floor space
– Fewer parts to manage
- Greater reliability and availability:
– Built-in hardware redundancy
– Decades of reliability, availability, and serviceability (RAS) innovation
– Capacity and backup on demand
– Decades-proven virtualization security protecting sensitive data and critical business processes in the cloud
– Resiliency management and fewer points of failure
– Extending IBM z Systems™ security to a private network across heterogeneous resources
As an example of this cloud solution, we use a telecom provider that selected the IBM z Systems platform for the provider's Linux operating system consolidation and virtualization. That company wants to build a cloud platform but also wants to reduce its cost of operation and overall data center footprint. The company's strategy is to improve provisioning time for its business support system (BSS) and operational support system (OSS) to satisfy server requests of its users.
Figure 2 is an architectural overview for a cloud solution using Linux on z Systems.
