Moving Hadoop to the Cloud: Harnessing Cloud Features and Flexibility for Hadoop Clusters
by Bill HavankiUntil recently, Hadoop deployments existed on hardware owned and run by organizations. Now, of course, you can acquire the computing resources and network connectivity to run Hadoop clusters in the cloud. But there’s a lot more to deploying Hadoop to the public cloud than simply renting machines.This hands-on guide shows developers and systems administrators familiar with Hadoop how to install, use, and manage cloud-born clusters efficiently. You’ll learn how to architect clusters that work with cloud-provider features—not just to avoid pitfalls, but also to take full advantage of these services. You’ll also compare the Amazon, Google, and Microsoft clouds, and learn how to set up clusters in each of them.Learn how Hadoop clusters run in the cloud, the problems they can help you solve, and their potential drawbacksExamine the common concepts of cloud providers, including compute capabilities, networking and security, and storageBuild a functional Hadoop cluster on cloud infrastructure, and learn what the major providers requireExplore use cases for high availability, relational data with Hive, and complex analytics with SparkGet patterns and practices for running cloud clusters, from designing for price and security to dealing with maintenance
Type Inheritance and Relational Theory: Subtypes, Supertypes, and Substitutability
by C. J. DateType inheritance is that phenomenon according to which we can say, for example, that every square is also a rectangle, and so properties that apply to rectangles in general apply to squares in particular. In other words, squares are a subtype of rectangles, and rectangles are a supertype of squares. Recognizing and acting upon such subtype / supertype relationships provides numerous benefits: Certainly it can help in data modeling, and it can also provide for code reuse in applications. For these reasons, many languages, including the standard database language SQL, have long supported such relationships. However, there doesn't seem to be any consensus in the community at large on a formal, rigorous, and abstract model of inheritance. This book proposes such a model, one that enjoys several advantages over other approaches, not the least of which it is that it's fully compatible with the well known relational model of data.Topics the model covers include:Both single and multiple inheritanceScalar, tuple, and relation inheritanceType lattices and union and intersection typesPolymorphism and substitutabilityCompile time and run time bindingAll of these topics are described in detail in the book, with numerous illustrative examples, exercises, and answers. The book also discusses several alternative approaches. In particular, it includes a detailed discussion and analysis of inheritance as supported in the SQL standard.

Zero Trust Networks: Building Secure Systems in Untrusted Networks
by Doug Barth Evan GilmanThe perimeter defenses guarding your network perhaps are not as secure as you think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. That’s an all-too-familiar scenario today. With this practical book, you’ll learn the principles behind zero trust architecture, along with details necessary to implement it.The Zero Trust Model treats all hosts as if they’re internet-facing, and considers the entire network to be compromised and hostile. By taking this approach, you’ll focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility.Understand how perimeter-based defenses have evolved to become the broken model we use todayExplore two case studies of zero trust in production networks on the client side (Google) and on the server side (PagerDuty)Get example configuration for open source tools that you can use to build a zero trust networkLearn how to migrate from a perimeter-based network to a zero trust network in production

Refactoring JavaScript: Turning Bad Code Into Good Code
by Evan BurchardHow often do you hear people say things like this? "Our JavaScript is a mess, but we’re thinking about using [framework of the month]."Like it or not, JavaScript is not going away. No matter what framework or ”compiles-to-js” language or library you use, bugs and performance concerns will always be an issue if the underlying quality of your JavaScript is poor. Rewrites, including porting to the framework of the month, are terribly expensive and unpredictable. The bugs won’t magically go away, and can happily reproduce themselves in a new context. To complicate things further, features will get dropped, at least temporarily.The other popular method of fixing your JS is playing “JavaScript Jenga,” where each developer slowly and carefully takes their best guess at how the out-of-control system can be altered to allow for new features, hoping that this doesn’t bring the whole stack of blocks down. This book provides clear guidance on how best to avoid these pathological approaches to writing JavaScript:Recognize you have a problem with your JavaScript quality.Forgive the code you have now, and the developers who made it.Learn repeatable, memorable, and time-saving refactoring techniques.Apply these techniques as you work, fixing things along the way.Internalize these techniques, and avoid writing as much problematic code to begin with.Bad code doesn’t have to stay that way. And making it better doesn’t have to be intimidating or unreasonably expensive.
