Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Systems Performance: Enterprise and the Cloud focuses on Linux(R) and Unix(R) performance, while illuminating performance issues that are relevant to all operating systems. You'll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare-metal systems and virtualized cloud tenants running Linux-based Ubuntu(R), Fedora(R), CentOS, and the illumos-based Joyent(R) SmartOS(TM) and OmniTI OmniOS(R). He systematically covers modern systems performance, including the "traditional" analysis of CPUs, memory, disks, and networks, and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the "unknown unknowns" of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish. Coverage includes - Modern performance analysis and tuning: terminology, concepts, models, methods, and techniques - Dynamic tracing techniques and tools, including examples of DTrace, SystemTap, and perf - Kernel internals: uncovering what the OS is doing - Using system observability tools, interfaces, and frameworks - Understanding and monitoring application performance - Optimizing CPUs: processors, cores, hardware threads, caches, interconnects, and kernel scheduling - Memory optimization: virtual memory, paging, swapping, memory architectures, busses, address spaces, and allocators - File system I/O, including caching - Storage devices/controllers, disk I/O workloads, RAID, and kernel I/O - Network-related performance issues: protocols, sockets, interfaces, and physical connections - Performance implications of OS and hardware-based virtualization, and new issues encountered with cloud computing - Benchmarking: getting accurate results and avoiding common mistakes This guide is indispensable for anyone who operates enterprise or cloud environments: system, network, database, and web admins; developers; and other professionals. For students and others new to optimization, it also provides exercises reflecting Gregg's extensive instructional experience.

    Reveals how to run an online business profitably in spite of the Internet's inherently free culture, disseminating the principles of a ''priceless economy'' in six categories that pertain to advertising, labor exchange, and advanced-version fees.

    Mainstream agile approaches that are indeed suitable for small projects require significant tailoring for larger, complex enterprise projects. In "Disciplined Agile Delivery," Scott W. Ambler and Mark Lines introduce IBM's breakthrough Disciplined Agile Delivery (DAD) process framework, which describes how to do this tailoring. DAD applies a more disciplined approach to agile development by acknowledging and dealing with the realities and complexities of a portfolio of interdependent program initiatives. Ambler and Lines show how to extend Scrum with supplementary agile and lean strategies from Agile Modeling (AM), Extreme Programming (XP), Kanban, Unified Process (UP), and other proven methods to provide a hybrid approach that is adaptable to your organization's unique needs. They candidly describe what practices work best, why they work, what the trade-offs are, and when to consider alternatives, all within the context of your situation. "Disciplined Agile Delivery "addresses agile practices across the entire lifecycle, from requirements, architecture, and development to delivery and governance. The authors show how these best-practice techniques fit together in an end-to-end process for successfully delivering large, complex systems--from project initiation through delivery. Coverage includesScaling agile for mission-critical enterprise endeavorsAvoiding mistakes that drive poorly run agile projects to chaosEffectively initiating an agile projectTransitioning as an individual to agileIncrementally building consumable solutionsDeploying agile solutions into complex production environmentsLeveraging DevOps, architecture, and other enterprise disciplinesAdapting your governance strategy for agile projects Based on facts, research, and extensive experience, this book will be an indispensable resource for every enterprise software leader and practitioner--whether they're seeking to optimize their existing agile/Scrum process or improve the agility of an iterative process.

    I would love to write that book, but at this time I have no indication that such a book would be worth writing. Most books fail in the market, and most of them fail not because they are poorly written or edited, but because there aren’t enough people interested in them. They are not the right it.What you are reading now is a pretotype edition of the book. I wrote and “edited” it in days instead of months, just to test the level of interest in such a book. I had a few friends and colleagues review it, but don’t be surprised if you find typos, misspellings, bad grammar, awkward formatting and all sorts of misteaks.Releasing it in its present state is not easy for me.The toughest thing about pretotyping is not developing pretotypes, that’s the fun part. The tough part is getting over our compulsion for prema- ture perfectionism and our desire to add more features, or content, before releasing the first version. The tough part is getting our pretotypes in front of people, where they will be judged, criticized and – possibly – rejected.Reid Hoffman, founder of LinkedIn once said: “If you are not embarrassed by the first version of your product, you’ve launched too late.”I am plenty embarrassed. I must be on the right track.http://www.pretotyping.org/pretotype-...

    It has sold 30,000 copies in each edition and will continue to reach a huge academic audience.In this renowned book, Everett M. Rogers, professor and chair of the Department of Communication & Journalism at the University of New Mexico, explains how new ideas spread via communication channels over time. Such innovations are initially perceived as uncertain and even risky. To overcome this uncertainty, most people seek out others like themselves who have already adopted the new idea. Thus the diffusion process consists of a few individuals who first adopt an innovation, then spread the word among their circle of acquaintances--a process which typically takes months or years. But there are exceptions: use of the Internet in the 1990s, for example, may have spread more rapidly than any other innovation in the history of humankind. Furthermore, the Internet is changing the very nature of diffusion by decreasing the importance of physical distance between people. The fifth edition addresses the spread of the Internet, and how it has transformed the way human beings communicate and adopt new ideas.

    The Art of Action is a thought-provoking and fresh look at how managers can turn planning into execution, and execution into results.Drawing on his experience as a consultant, senior manager and a highly respected military historian, Stephen Bungay takes a close look at the nineteenth-century Prussian Army, which built its agility on the initiative of its highly empowered junior officers, to show business leaders how they can build more effective, productive organizations. Based on a theoretical framework which has been tested in practice over 150 years, Bungay shows how the approach known as "mission command" has been applied in businesses as diverse as pharmaceuticals and F1 racing today. The Art of Action is scholarly but engaging, rigorous but pragmatic, and shows how common sense can sometimes be surprising.

    Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves.The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns as your guide, you will learn how these important patterns fit into the software development process, and how you can leverage them to solve your own design problems most efficiently. Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other design constraints, and the consequences and trade-offs of using the pattern within a larger design. All patterns are compiled from real systems and are based on real-world examples. Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk.

    Indeed, that's what computers are for. You can enlist your own computer to automate all of your project's repetitive tasks, ranging from individual builds and running unit tests through to full product release, customer deployment, and monitoring the system.Many teams try to do these tasks by hand. That's usually a really bad idea: people just aren't as good at repetitive tasks as machines. You run the risk of doing it differently the one time it matters, on one machine but not another, or doing it just plain wrong. But the computer can do these tasks for you the same way, time after time, without bothering you. You can transform these labor-intensive, boring and potentially risky chores into automatic, background processes that just work.In this eagerly anticipated book, you'll find a variety of popular, open-source tools to help automate your project. With this book, you will learn: How to make your build processes accurate, reliable, fast, and easy. How to build complex systems at the touch of a button. How to build, test, and release software automatically, with no human intervention. Technologies and tools available for automation: which to use and when. Tricks and tips from the masters (do you know how to have your cell phone tell you that your build just failed?) You'll find easy-to-implement recipes to automate your Java project, using the same popular style as the rest of our Jolt Productivity Award-winning Starter Kit books.

    In 1999, Tony introduced Clayton Christensen to the idea that “people have underlying needs or processes in their lives, that they are addressing in some way right now”—an insight that was to become Jobs-to-be-Done Theory. For 25 years, Ulwick and his company, Strategyn, have helped over 400 companies, applying Jobs-to-be-Done Theory in practice with a success rate of 86%—a 5-fold improvement. “Ulwick has taken the guesswork out of innovation,” says the ‘father of modern marketing,’ Philip Kotler, S. C. Johnson Distinguished Professor of International Marketing at the Kellogg School of Management, Northwestern University. “He has done this by introducing us to Jobs-to-be-Done theory, and converting it to practice using his rigorous innovation process known as Outcome-Driven Innovation. I call him the Deming of Innovation because, more than anyone else, Tony has turned innovation into a science,” adds Kotler. LEARN - Why companies fail at innovation and how to avoid critical mistakes. - How to employ the Jobs-to-be-Done Theory Needs Framework to categorize, define, capture, and prioritize customer needs. - A Jobs-to-be-Done Growth Strategy Matrix to categorize, understand, and employ the 5 strategies that drive growth. - Outcome-Based Segmentation: how does it create new opportunities? - The details of the innovation process known as Outcome-Driven Innovation. It ties customer-defined metrics to the customer’s Job-to-be-Done, transforming every aspect of opportunity discovery, marketing and innovation. - The Language of Job-to-be-Done – the syntax and lexicon of innovation.

    He needed a way to keep track of software development over time – whatever he was thinking about or working on. He researched subjects he found interesting, then documented his research with a public blog post, which he could easily find and refer to later.
