The world has changed. With the new cloud options, enterprises no longer must rely on only their IT organization to meet their computing needs. Business units now have options that were not available just a few years ago. They can get some of their needs met by traditional IT processes, and reach out to a cloud provider to meet other needs. The concern is that if you, working in a traditional IT organization, do not meet these needs, someone else will. This IBM® Redbooks® publication helps you to understand the benefits of becoming your own cloud service provider. It describes a simple approach that allows you to be successful. The main focus of the book is lessons learned from the implementation by an IBM client, Walmart Stores, Inc.®, that achieved impressive results in their efforts to become their own cloud service provider to their developer community. In this way, Walmart successfully made z Systems a relevant part of their Hybrid Cloud strategy. Walmart embarked on this journey to help their application developers achieve results that were previously time-consuming and difficult to deliver. In the process, they realized that they had everything that they needed to become a services provider to their developer community. This book describes the choices that Walmart made, and explains the steps they took to be successful. The goal of the book is not to imply that the only way to achieve success is by following Walmart's process exactly. Rather, this book allows you to use the same basic constructs, but choose implementation details that fit your environment so that you can achieve success on your own terms. With IBM CICS® Transaction Server (TS) for z/OS®, you also have the resources for a successful transition to becoming your own cloud service provider. IBM Design Thinking is a methodology that is used by designers to solve complex problems by focusing on individual user roles. This book is organized from the viewpoint of these roles in the IT organization. It provides guidance in the following areas: What does the line of business expect from a cloud service? What topology and high availability characteristics does the system programmer need? What unique facilities does IBM CICS provide to the service developer? How does a developer discover and consume services in an application? How does the operations team manage the service in production? One of the services that Walmart built and how the decisions made by each job role affected the overall outcome of the service are used as an example throughout this book. It shares the experience of the team that created this and other business critical cloud services that are all hosted in CICS. Comments from Walmart IT leaders that were captured during the authoring process are presented to emphasize why the company adopted cloud and how cloud has helped Walmart to achieve success. Developers understand the risk protection that IT groups provide. They also understand that waiting to move applications to production, or for a service to be provisioned, compromises the agile environment required by today's businesses. This book is intended for enterprise service providers looking to enable their developers to increase the speed at which functionality is delivered to the business.

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 shortage of approaches to cloud computing exists. This book focuses on a pragmatic approach for enterprises that are struggling to take advantage of their business assets in the cloud. This book introduces the basic cloud concepts as defined by the National Institute of Standards and Technology (NIST). Each chapter explains the importance of a particular NIST characteristic, the z/OS role in accomplishing the characteristic, and how it was implemented by the Walmart Technology team. This book is intended for IT professionals who are considering extending their IBM z SystemsTM environment to a hybrid cloud by unleashing the power of cloud services on z/OS.

It's easy to look at the title of a book and think "that's old news" or "I already know all there is to know on that subject." But before you dismiss this publication, consider just how far the IBM® Parallel Sysplex® architecture has come. From the early days the mainframe has embraced a shared everything approach. The original designers coded IBM z/OS® (called IBM MVSTM or IBM OS/390® back then) with the functionality necessary for the operating system to create the repositories, manage the data flow, and ensure the integrity of the systems involved. From there, the middleware systems provided the exploitation and advanced functions to mature the technology. The component in the middle of all this great technology can easily be taken for granted. That is the IBM Coupling Facility. This IBM Redbooks® publication discusses both traditional uses for the IBM Coupling Facility technology and new ways to use it with products such as IBM CICS®. You can learn how to perform new functions and have these functions benefit from the scalability and availability achieved only in a mainframe ecosystem. Open standards are a large part of considerations today, as most companies run IT shops with a mix of technology components. As the world embraces these technologies, it is necessary to understand how to mix the world of mainframe architectures and products with other open architectures. This mix allows the best tool to be used to solve processing needs, at the right cost and service levels. Often the functions needed for modern processing can be found in house, in places where staff are skilled and that already deliver the robust production environments you count on daily. This book discusses these modern functions and how to achieve them with CICS use of the IBM Coupling Facility. You will learn how one IBM client, Walmart, took these concepts far beyond the original design as they share their experiences and even share code examples to help you get started. The last chapter of this book shows what can be achieved when a combination of old and new functions are use together. Even if you have familiarity with what could be done with the IBM Coupling Facility in the past, there is much to learn and deploy in a modern world. Those who are familiar with the IBM Coupling Facility might find the content of this book helpful. Additionally, readers who are considering how to use the IBM Coupling Facility technology within their environment might also find useful information in the chapters that follow

Cloud computing opens a broad range of business opportunities across the computing industry and enables companies in other industries to provide services to their employees, customers, and partners. Cloud computing provides a compelling approach to addressing this opportunity. The IBM® SmartCloudTM for Service Providers portfolio can dramatically lower the business and technical barriers of entry to cloud computing. Companies rely on their business applications and systems as an integral part of their business. They can expand the business value of their applications and systems by using cloud computing to enable delivery of these functions as services. Companies have various options when adopting cloud computing. They can: Use existing service providers to operate services on their behalf. Implement hybrid solutions that extend existing applications through integration with cloud services. Add cloud service hosting capability to their existing facilities. For ecosystem partners, cloud computing provides compelling capabilities that ease deployment and long term management and maintenance. Equally important, cloud computing facilitates a more flexible business and technical environment. This environment can expand, contract, and adapt as services are added, removed, and evolve. The cloud replaces physical activity associated with change and change management by creating a fluid environment that adapts through automation. This IBM RedguideTM publication describes the business and technology choices companies make when entering the cloud service provider space. It introduces various cloud service provider business models and shows how to apply them to your business. This guide introduces the IBM CCRA cloud service provider adoption pattern, providing guidance about the definition, architecture, and deployment of cloud computing environments. Two cloud service provider deployment scenarios are highlighted throughout the guide, and they reflect the two most common starting points for service providers entering the cloud computing marketplace. The guide culminates with details about these deployment scenarios, and showing how they can be deployed today.

This book provides a structured treatment of the key principles and techniques for enabling efficient processing of deep neural networks (DNNs). DNNs are currently widely used for many artificial intelligence (AI) applications, including computer vision, speech recognition, and robotics. While DNNs deliver state-of-the-art accuracy on many AI tasks, it comes at the cost of high computational complexity. Therefore, techniques that enable efficient processing of deep neural networks to improve key metrics—such as energy-efficiency, throughput, and latency—without sacrificing accuracy or increasing hardware costs are critical to enabling the wide deployment of DNNs in AI systems. The book includes background on DNN processing; a description and taxonomy of hardware architectural approaches for designing DNN accelerators; key metrics for evaluating and comparing different designs; features of DNN processing that are amenable to hardware/algorithm co-design to improve energy efficiency and throughput; and opportunities for applying new technologies. Readers will find a structured introduction to the field as well as formalization and organization of key concepts from contemporary work that provide insights that may spark new ideas.
