Book excerpt: Most companies today are firmly on the social and environmental issues ‘bandwagon’, like bees around a honey pot, from plastic in oceans through to diversity. As a result, people are increasingly distrustful of these efforts which they view as cheap marketing stunts meant to wow people into buying more. "Try to fly like a superman, and you will come down like a tin of soup." Market economists have long told us that we’re driven only by money and status, but the inherent human truth that cuts across age, culture and gender uncovers a stronger force: we wish to be in charge of our own lives and our own happiness. Through extensive growth and affinity research, world-renowned purpose-pioneer, Thomas Kolster, uncovers a simple answer that is key to driving marketing growth in the 21st century: if you put people in control of the marketing mix, from products to promotion, they can grow and in turn grow your organisation. This book explains the meteoric rise of a company like AirBnB, how a 20-something Swede, Maria de la Croix, built a global coffee empire like Wheelys in just a few years, and how a group of friends hanging out in a bar in Melbourne created one of the largest global non-profits fighting for men’s health, Movember – and how you can empower people to do the same. Today’s power no longer rests in the hands of the privileged few, but in the talented many. It is time for you to unleash that power, in numbers. Drawing on top-line marketing case studies and in-depth interviews, Kolster demonstrates how people are truly motivated to act when they’re in charge of their own life and happiness. ‘Who can you help me become?’ is the one essential question you need to be asking and acting on to chart a new course for your organisation, changing behaviours at scale and unlocking sustainable growth that benefits all.

This book was released on 2014-01-27 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 40 years, IBM® mainframes have supported an extraordinary portion of the world's computing work, providing centralized corporate databases and mission-critical enterprise-wide applications. The IBM System z®, the latest generation of the IBM distinguished family of mainframe systems, has come a long way from its IBM System/360 heritage. Likewise, its IBM z/OS® operating system is far superior to its predecessors in providing, among many other capabilities, world-class and state-of-the-art support for the TCP/IP Internet protocol suite. TCP/IP is a large and evolving collection of communication protocols managed by the Internet Engineering Task Force (IETF), an open, volunteer organization. Because of its openness, the TCP/IP protocol suite has become the foundation for the set of technologies that form the basis of the Internet. The convergence of IBM mainframe capabilities with Internet technology, connectivity, and standards (particularly TCP/IP) is dramatically changing the face of information technology and driving requirements for even more secure, scalable, and highly available mainframe TCP/IP implementations. The IBM z/OS Communications Server TCP/IP Implementation series provides understandable, step-by-step guidance about how to enable the most commonly used and important functions of z/OS Communications Server TCP/IP. This IBM Redbooks® publication is for people who install and support z/OS Communications Server. It starts with a discussion of virtual IP addressing (VIPA) for high-availability, with and without a dynamic routing protocol. It describes several workload balancing approaches with the z/OS Communications Server. It also explains optimized Sysplex Distributor intra-sysplex load balancing. This function represents improved application support using optimized local connections together with weight values from extended Workload Manager (WLM) interfaces. Finally, this book highlights important tuning parameters and suggests parameter values to maximize performance in many client installations.

This book was released on 2014-10-30 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Linux on System z becomes more prevalent and mainstream in the industry, the need for it to deliver higher levels of availability is increasing. This IBM Redbooks publication starts with an explanation of high availability (HA) fundamentals such as HA concepts and terminology. It continues with a discussion of why a business needs to consider an HA solution and then explains how to determine your business single points of failure. We outline the components of a high availability solution and describe these components. Then we provide some architectural scenarios and demonstrate how to plan and decide an implementation of an end-to-end HA solution, from Linux on System z database scenarios to z/OS, and include storage, network, z/VM, Linux, and middleware. This implementation includes the IBM Tivoli System Automation for Multiplatforms (TSA MP), which monitors and automates applications distributed across Linux, AIX®, and z/OS® operating systems, as well as a GDPS based solution. It includes the planning for an end-to-end scenario, considering Linux on System z, z/VM, and z/OS operating environments, and the middleware used. The TSA MP implements HA for infrastructure, network, operating systems, and applications across multiple platforms and is compared to a Linux HA implementation based on open source Linux-HA, which is Linux only.
