Kubernetes: Up and RunningLegend has it that Google deploys over two billion application containers a week. How's that possible? Google revealed the secret through a project called Kubernetes, an open source cluster orchestrator (based on its internal Borg system) that radically simplifies the task of building, deploying, and maintaining scalable distributed systems in the cloud. This practical guide shows you how Kubernetes and container technology can help you achieve new levels of velocity, agility, reliability, and efficiency.
Authors Kelsey Hightower, Brendan Burns, and Joe Beda - who've worked on Kubernetes at Google and other organizatons - explain how this system fits into the lifecycle of a distributed application. You will learn how to use tools and APIs to automate scalable distributed systems, whether it is for online services, machine-learning applications, or a cluster of Raspberry Pi computers.

To help bridge the divide between these two worlds, this practical guide introduces several security tools and techniques adapted specifically to integrate with agile development.
Written by security experts and agile veterans, this book begins by introducing security principles to agile practitioners, and agile principles to security practitioners. The authors also reveal problems they encountered in their own experiences with agile security, and how they worked to solve them.
Add security practices to each stage of your existing development lifecycle; Integrate security with planning, requirements, design, and at the code level; Include security testing as part of your team's effo ...
The Customer-Driven PlaybookDespite the wide acceptance of Lean approaches and customer-development strategies, many product teams still have difficulty putting these principles into meaningful action. That's where The Customer-Driven Playbook comes in. This practical guide provides a complete end-to-end process that will help you understand customers, identify their problems, conceptualize new ideas, and create fantastic products they'll love.
To build successful products, you need to continually test your assumptions about your customers and the products you build. This book shows team leads, researchers, designers, and managers how to use the Hypothesis Progression Framework (HPF) to formulate, experiment with, and make sense of critical customer and product assumptions at every stage. With helpful tips, real-world examples, and complete guides, you'll quickly learn how to turn Lean theory into action.
Collect and formulate your assumptions into hypotheses that can be tested to unlock meaningful insights ...
Agile Data Science 2.0Data science teams looking to turn research into useful analytics applications require not only the right tools, but also the right approach if they're to succeed.

Spock: Up and RunningMost developers would agree that writing automated tests is a good idea, but writing good, well-structured tests is still an elusive skill for many. For Java and Groovy developers, however, there's good news. This practical guide shows you how to write concise and highly readable tests with Spock, the most innovative testing and specification framework for the JVM since JUnit.
Author Rob Fletcher takes you from Spock basics to advanced topics, using fully worked integration examples. Through the course of this book, you'll build a simple web application - Squawker - that allows users to post short messages. You'll discover how much easier it is to write automated tests with Spock's straightforward and expressive language.
Start by learning how to write simple unit tests; Understand the lifecycle of Spock specifications and feature methods; Dive into interaction testing, using Spock's intuitive syntax for dealing with mocks and stubs; Learn about parameterized tests - writing feat ...
Learning HTTP/2What can your organization gain by adopting HTTP/2? How about faster, simpler, and more robust websites and applications?

React 16 ToolingReact 16 Tooling covers the most important tools, utilities, and libraries that every React developer needs to know - in detail. As React has grown, the amazing toolset around it has also grown, adding features and enhancing the development workflow. Each of these essential tools is presented in a practical manner and in a logical order mirroring the development workflow. These tools will make your development life simpler and happier, enabling you to create better and more performant apps.
Adam starts with a hand-picked selection of the best tools for the React 16 ecosystem. For starters, there's the create-react-app utility that's officially supported by the React team. Not only does this tool bootstrap your React project for you, it also provides a consistent and stable framework to build upon. The premise is that when you don't have to think about meta development work, more focus goes into the product itself.
Other React tools follow this same approach to automating and impr ...
