Clouds are distributed technology platforms that leverage sophisticated technology innovations to provide highly scalable and resilient environments that can be remotely utilized by organizations in a multitude of powerful ways. To successfully build upon, integrate with, or even create a cloud environment requires an understanding of its common inner mechanics, architectural layers, and models, as well as an understanding of the business and economic factors that result from the adoption and real-world use of cloud-based services. In Cloud Computing: Concepts, Technology & Architecture, Thomas Erl, one of the world’s top-selling IT authors, teams up with cloud computing experts and researchers to break down proven and mature cloud computing technologies and practices into a series of well-defined concepts, models, technology mechanisms, and technology architectures, all from an industry-centric and vendor-neutral point of view. In doing so, the book establishes concrete, academic coverage with a focus on structure, clarity, and well-defined building blocks for mainstream cloud computing platforms and solutions. Subsequent to technology-centric coverage, the book proceeds to establish business-centric models and metrics that allow for the financial assessment of cloud-based IT resources and their comparison to those hosted on traditional IT enterprise premises. Also provided are templates and formulas for calculating SLA-related quality-of-service values and numerous explorations of the SaaS, PaaS, and IaaS delivery models. With more than 260 figures, 29 architectural models, and 20 mechanisms, this indispensable guide provides a comprehensive education of cloud computing essentials that will never leave your side.
The Phoenix Project
Bill is an IT manager at Parts Unlimited. It's Tuesday morning and on his drive into the office, Bill gets a call from the CEO. The company's new IT initiative, code named Phoenix Project, is critical to the future of Parts Unlimited, but the project is massively over budget and very late. The CEO wants Bill to report directly to him and fix the mess in ninety days or else Bill's entire department will be outsourced. With the help of a prospective board member and his mysterious philosophy of The Three Ways, Bill starts to see that IT work has more in common with manufacturing plant work than he ever imagined. With the clock ticking, Bill must organize work flow, streamline interdepartmental communications, and effectively serve the other business functions at Parts Unlimited. In a fast-paced and entertaining style, three luminaries of the DevOps movement deliver a story that anyone who works in IT will recognize. Readers will not only learn how to improve their own IT organizations, they'll never view IT the same way again.
Using lively case studies, this book analyzes the transformation of crime and terrorism and the business logic of terrorism.
A revelatory examination of the most significant demographic shift since the Baby Boom—the sharp increase in the number of people who live alone—that offers surprising insights on the benefits of this epochal change In 1950, only 22 percent of American adults were single. Today, more than 50 percent of American adults are single, and 31 million—roughly one out of every seven adults—live alone. People who live alone make up 28 percent of all U.S. households, which makes them more common than any other domestic unit, including the nuclear family. In GOING SOLO, renowned sociologist and author Eric Klinenberg proves that these numbers are more than just a passing trend. They are, in fact, evidence of the biggest demographic shift since the Baby Boom: we are learning to go solo, and crafting new ways of living in the process. Klinenberg explores the dramatic rise of solo living, and examines the seismic impact it’s having on our culture, business, and politics. Though conventional wisdom tells us that living by oneself leads to loneliness and isolation, Klinenberg shows that most solo dwellers are deeply engaged in social and civic life. In fact, compared with their married counterparts, they are more likely to eat out and exercise, go to art and music classes, attend public events and lectures, and volunteer. There’s even evidence that people who live alone enjoy better mental health than unmarried people who live with others and have more environmentally sustainable lifestyles than families, since they favor urban apartments over large suburban homes. Drawing on over three hundred in-depth interviews with men and women of all ages and every class, Klinenberg reaches a startling conclusion: in a world of ubiquitous media and hyperconnectivity, this way of life can help us discover ourselves and appreciate the pleasure of good company. With eye-opening statistics, original data, and vivid portraits of people who go solo, Klinenberg upends conventional wisdom to deliver the definitive take on how the rise of living alone is transforming the American experience. GOING SOLO is a powerful and necessary assessment of an unprecedented social change.

Wireshark Network Analysis
"Network analysis is the process of listening to and analyzing network traffic. Network analysis offers an insight into network communications to identify performance problems, locate security breaches, analyze application behavior, and perform capacity planning. Network analysis (aka "protocol analysis") is a process used by IT professionals who are responsible for network performance and security." -- p. 2.
The End of Normal
From one of the most respected economic thinkers and writers of our time, a brilliant argument about the history and future of economic growth. The years since the Great Crisis of 2008 have seen slow growth, high unemployment, falling home values, chronic deficits, a deepening disaster in Europe—and a stale argument between two false solutions, “austerity” on one side and “stimulus” on the other. Both sides and practically all analyses of the crisis so far take for granted that the economic growth from the early 1950s until 2000—interrupted only by the troubled 1970s—represented a normal performance. From this perspective, the crisis was an interruption, caused by bad policy or bad people, and full recovery is to be expected if the cause is corrected. The End of Normal challenges this view. Placing the crisis in perspective, Galbraith argues that the 1970s already ended the age of easy growth. The 1980s and 1990s saw only uneven growth, with rising inequality within and between countries. And the 2000s saw the end even of that—despite frantic efforts to keep growth going with tax cuts, war spending, and financial deregulation. When the crisis finally came, stimulus and automatic stabilization were able to place a floor under economic collapse. But they are not able to bring about a return to high growth and full employment. In The End of Normal, “Galbraith puts his pessimism into an engaging, plausible frame. His contentions deserve the attention of all economists and serious financial minds across the political spectrum” (Publishers Weekly, starred review).
