Creating IBM z/OS Cloud Services
This IBM® Redbooks® publication discusses the real world experience of an enterprise that developed and implemented IBM z/OS® cloud services. This book shares the experience of a team at Walmart Technology, Walmart Stores, Inc.® and some of the decisions they made to create business critical cloud services. These experiences and approaches relate to the z/OS platform, and might not apply to other hybrid cloud approaches. This book highlights the strengths and characteristics of z/OS that led the Walmart infrastructure and software engineers to use this platform as they transitioned from a traditional IT deployment to a cloud model. Embarking on a cloud strategy can be overwhelming. No sh...
Performance and Capacity Themes for Cloud Computing
This IBM® RedpaperTM is the second in a series that addresses the performance and capacity considerations of the evolving cloud computing model. The first Redpaper publication (Performance Implications of Cloud Computing, REDP-4875) introduced cloud computing with its various deployment models, support roles, and offerings along with IT performance and capacity implications associated with these deployment models and offerings. In this redpaper, we discuss lessons learned in the two years since the first paper was written. We offer practical guidance about how to select workloads that work best with cloud computing, and about how to address areas, such as performance testing, monitoring, se...
Walmart and the CICS Asynchronous API: An Adoption Experience
This IBM® Redbooks® publication discusses practical uses of the IBM CICS asynchronous API capability. It describes the methodology, design and thought process used by a large client, Walmart, and the considerations of the choices made. The Redbooks publication provides real life examples and application patterns that benefit from the performance and scalability offered by the new API. The book discusses the homegrown methodology used by Walmart before the API was available and compares it with the design using the new API. A discussion of the process used to migrate older applications to begin using the new API is included so the reader will understand the ease of implementing the new API....
Implementing IBM SmartCloud Entry on IBM PureFlex System
Distributed computing has been transformed with the introduction of virtualization technology. This has driven a re-architecture of traditional data center workload placement. In 2012, IBM® announced IBM PureSystemsTM, a new offering based on preconfigured software, servers, and storage that form an expert integrated system. Expert integrated systems now combine traditional IT resources into a single optimized solution, with prepackaged components including servers, storage devices, networking equipment, and software. With this evolution of technology, we move from discrete, siloed, and underutilized IT resources to shared resource pools. This IBM Redbooks® publication can help you install, tailor, and configure IBM SmartCloud® Entry on the IBM PureFlexTM System offering. This book is intended for anyone who wants to learn more about cloud computing with IBM SmartCloud Entry and offerings based on IBM Flex SystemTM elements.

Deploying a Cloud on IBM System z
Cloud computing, using shared resources in public spaces instead of in-house IT organizations, is the latest thing in IT. Lines of business even bypass their own IT shops to take advantage of external providers of cloud offerings. However, many of the users that employ public cloud services have not considered issues involving security, compliance, and availability. Cloud represents a new business model that requires a process discipline as well as the use of a corresponding set of technologies. The new model requires an understanding of the hardware configuration, software images, a virtualized storage infrastructure, and network management. For many organizations that have mainframe resour...
