In the dynamic business environment of today, Information Technology (IT) organizations face challenges around scalability and performance. This IBM® Redbooks® publication is targeted for IT architects, IT personnel, and developers who are looking to integrate caching technologies, specifically elastic caching, into their business environment to enhance scalability and performance. Although it is helpful to know caching technologies, an introduction to caching technologies in general is included. In addition, technical details are provided about implementing caching by using several IBM products. The IBM WebSphere® eXtreme Scale product provides several functions to enhance application performance and scalability. It provides distributed object caching functionality, which is essential for elastic scalability and next-generation cloud environments. It helps applications process massive volumes of transactions with extreme efficiency and linear scalability. By using the scalable in-memory data grid, enterprises can benefit from a powerful, high-performance elastic cache. The IBM WebSphere DataPower® XC10 Appliance enables your business-critical applications to scale cost effectively with consistent performance by using elastic caching in a purpose-built, easy-to-use appliance. This publication explains the benefits of using various caching techniques in your enterprise, specifically involving the use of IBM WebSphere eXtreme Scale and the IBM WebSphere DataPower XC10 Appliance. Three real-world scenarios are described that use these enterprise caching technologies to solve issues that face the businesses of today.

IBM WebSphere® eXtreme Scale provides a solution to scalability issues through caching and grid technology. It provides an enhanced quality of service in high performance computing environments. This IBM® Redbooks® publication introduces WebSphere eXtreme Scale and shows how to set up and use an eXtreme Scale environment. It begins with a discussion of the issues that would lead you to an eXtreme Scale solution. It then describes the architecture of eXtreme Scale to help you understand how the product works. It provides information about potential grid topologies, the APIs used by applications to access the grid, and application scenarios that show how to effectively use the grid. This book is intended for architects who want to implement WebSphere eXtreme Scale. The original edition of this book was based on WebSphere eXtreme Scale version 6.1. It was published in 2008 and described as a "User's Guide". This second edition updates the information based on WebSphere eXtreme Scale version 8.6, and covers key concepts and usage scenarios.

The mobile industry is evolving rapidly. An increasing number of mobile devices, such as smartphones and tablets, are sold every year and more people are accessing services from a mobile device than ever before. For an enterprise, this can mean that a growing number of customers, business partners, and even employees now expect to access services on a mobile channel. This opens new opportunities for the business but also presents new challenges, both in terms of business processes and information technology (IT) infrastructure. IBM® Worklight® is an open mobile application platform. It helps organizations of all sizes to efficiently develop, connect, run, and manage HTML5, hybrid, and native applications. IBM Worklight provides the essential elements needed for complete mobile application development, deployment, and management within a business. This IBM Redbooks® publication provides information necessary to design, develop, deploy, and maintain mobile applications using IBM Worklight Version 5.0.5. It includes information about decision points that the IT organization will need to make, the roles that are involved in a mobile strategy and the responsibilities of the individuals in those roles. It also describes integration points with other IBM products that can enhance the mobile solution. This book has two parts: Part 1 is for a business-oriented IT audience and addresses business aspects of the mobile industry. It is for the IT architect or CTO, who can translate business needs into information technology solutions Part 2 is intended for a technical audience, including application developers, testers, and system administrators.

This IBM® Redbooks® publication focuses on operational and managerial aspects for DataPower® appliance deployments. DataPower appliances provide functionality that crosses both functional and organizational boundaries, which introduces unique management and operational challenges. For example, a DataPower appliance can provide network functionality, such as load balancing, and at the same time, provide enterprise service bus (ESB) capabilities, such as transformation and intelligent content-based routing. This IBM Redbooks publication provides guidance at both a general and technical level for individuals who are responsible for planning, installation, development, and deployment. It is not intended to be a "how-to" guide, but rather to help educate you about the various options and methodologies that apply to DataPower appliances. In addition, many chapters provide a list of suggestions.

This IBM® Redbooks® publication will help you to better understand the effective use of the WebSphere® DataPower® family of appliances. It provides guidance on the best methods identified to date for building the various components that implement solutions, such as handling MQ-based message flows or creating authentication and authorization policies. The information and recommendations in this publication are the result of real world experiences using the appliances. Such experience shows that taking the time to plan a solution implementation before beginning the work yields the greatest savings in time and energy and the highest quality outcome. This publication begins with a checklist of items to consider when planning a DataPower solution. This publication is intended to provide answers or guidance to implementation problems often encountered by users of the appliance. This book is not intended to present complete solutions or templates because experience shows that every customer uses the appliance in their own unique environment with unique requirements. Thus, this publication provides a compendium of information about particular aspects of a solution. Use the Table of Contents or Index to find your current issue, and return to this publication when the next issue or question arises.

Throughout the history of the IT industry, integration has been an important part of most projects. Whether it is integration of transactions, data, or processes, each has challenges and associated patterns and antipatterns. In an age of mobile devices, social networks, and cloud services, and big data analytics, integration is more important than ever, but the scope of the challenge for IT projects has changed. Partner APIs, social networks, physical sensors and devices, all of these and more are important sources of capability or insight. It is no longer sufficient to integrate resources under control of the enterprise, because many important resources are in the ecosystem beyond enterprise boundaries. With this as the basic tenet, we address these questions: What are the current integration patterns that help enterprises become and remain competitive? How do you choose when to use which pattern? What is the topology for a "composable business"? And how do you accelerate the process of implementation through intelligent choice of supporting integration middleware? This IBM® Redbooks® publication guides integration practitioners and architects in choosing integration patterns and technologies.

Cloud computing provides companies with many capabilities to meet their business needs but can also mean that a hybrid architecture is created that includes on-premise systems and the cloud. Integration is needed to bridge the gap between the on-premise existing systems and the new cloud applications, platform, and infrastructure. IBM® WebSphere® Cast Iron® meets the challenge of integrating cloud applications with on-premise systems, cloud applications-to-cloud applications, and on-premise to on-premise applications. It contains a graphical development environment that provides built-in connectivity to many cloud and on-premise applications and reusable solution templates that can be downloaded from a solution repository. The integration solutions that are created can then run on either an on-premise integration appliance or the multi-tenant WebSphere Cast Iron Live cloud service. This IBM Redbooks® publication is intended for application integrators, integration designers, and administrators evaluating or already using IBM WebSphere Cast Iron. Executives, leaders, and architects who are looking for a way to integrate cloud applications with their on-premise applications are also shown how WebSphere Cast Iron can help to resolve their integration challenges. The book helps you gain an understanding of Cast Iron and explains how to integrate cloud and on-premise applications quickly and simply. It gives a detailed introduction to the development tool and the administration interfaces and how they are used. It also discusses security, high availability, and re-usability. The book also includes three detailed scenarios covering real-world implementations of a Cast Iron Integration Solution.
