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.

Virtualization

  • Higher utilization
  • Economy-of-scale benefits
  • Lower capital expense
  • Lower operating expense

Standardization
  • Easier access
  • Flexible pricing
  • Reuse and sharing
  • Easier integration

Automation
  • Faster cycle times
  • Lower support costs
  • Optimized utilization
  • Improved compliance
  • Optimized security
  • Better user experience


Business value

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:

Solution overview

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.

Usage scenarios

This scenario is for the energy and utilities industry : SAP Cloud and Automation solution on z Systems. In this scenario, the fictional energy and utilities company, Fictional Energy E1, chooses the z Systems platform with its SAP application running on Linux for z Systems and database on IBM z/OS®. Energy E1 wants to reduce the time spent to copy and refresh complete SAP systems from days to hours with a cloud solution and SAP system automation, which can automate, standardize, and increase the speed of day-to-day operations for SAP systems, reducing the risk of mistakes caused by human error. The company wants to reduce time spent on complex, repetitive tasks, freeing up skilled staff for higher value work and deliver higher operational efficiency, helping to slash costs and accelerate the time-to-value ratio for new workloads.

The IBM Entry Cloud Configuration solution automates complex tasks typically performed by administrators of databases, operating systems, storage systems, and SAP Basis. When combined with SAP NetWeaver LVM, the configuration can reduce the time spent to copy and refresh complete SAP systems from days to hours. The high degree of automation also improves the quality and efficiency of SAP operations. The Linux on z Systems, IBM Entry Cloud Configuration solution is the ideal productivity tool for any IT organization running SAP Business Suite on the IBM z13 with IBM DB2 for z/OS. It is well-suited for computer services organizations hosting SAP systems for their clients, and for any IT organization seeking to run its SAP operations with z Systems in an on-premises, self-managed, cloud computing environment. Figure 4 shows the added value of this solution and how the solution reduces operation and administration time when compared to traditional operations.
