DESCRIPTION In the cloud computing model, a cluster of physical computers hosts an environment that provides shared services (public and private) and offers the flexibility to easily add, remove, and expand virtual servers and applications. OpenStack is an open source framework that can be installed on individual physical servers to a cloud platform and enables the building of custom infrastructure (IaaS), platform (PaaS), and software (SaaS) services without the high cost and vendor lock-in associated with proprietary cloud platforms. OpenStack in Action offers real world use cases and step-by-step instructions to develop cloud platforms from inception to deployment. It explains the design of both the physical hardware cluster and the infrastructure services needed to create a custom cloud platform. It shows how to select and set up virtual and physical servers, implement software-defined networking, and the myriad other technical details required to design, deploy, and operate an OpenStack cloud in an enterprise. It also discusses the cloud operation techniques needed to establish security practices, access control, efficient scalability, and day-to-day DevOps practices. RETAIL SELLING POINTS Real world examples Thorough step-by-step instruction Shows how to harness the power of OpenStack AUDIENCE The book is perfect systems administrators, developers, and architects interested in the design, construction, and operation of clouds using OpenStack. No prior experience with OpenStack or cloud development required. ABOUT THE TECHNOLOGY OpenStack as a framework for managing, designing, defining, and utilizing cloud resources. There are over 13k OpenStack contributors in over 131 countries. Every major IT vendor has some form of OpenStack representation, even those with directly competing products.

DESCRIPTION Functional programming is a deep and potentially mind-bending discipline. Fortunately, Java developers don't have to master every aspect of FP to get a big boost in the performance, readability, and maintainability of their applications. By learning a few core FP principles, they can write code that's less prone to side effects and unwanted dependencies and which is much better suited to the parallel processing required by modern multi-core and distributed systems. Also, because units of functional code are designed to be modular and independent, FP reduces or eliminates many of the bugs development teams routinely face when managing a large codebase. Functional Programming in Java teaches Java developers how to incorporate the most powerful benefits of functional programming into new and existing Java code. Written to meet the needs of professional Java developers who want to introduce functional programming principles into new and legacy projects, this book uses examples, exercises, and illustrations to teach core FP principles such as referential transparency, immutability, persistence, and laziness. They’ll discover which of the new functionally-inspired features of Java 8 will help in applying FP principles to code—as well as which to avoid. In the end, they’ll be able to think functionally about coding tasks in Java and use FP to make their applications easier to understand, optimize, maintain, and scale. KEY FEATURES • Increases productivity • Easy to grasp examples and illustrations • Written for professional Java developers AUDIENCE Readers need to be comfortable with Java programming. No previous experience with functional programming is required. ABOUT THE TECHNOLOGY Functional programming is gaining momentum, mainly through adoption of new languages such as Scala, Clojure or Groovy, and through the new popularity of older languages such as Haskell or Erlang. And functional programming is coming to Java 8 with the addition of features such as lambda expressions, and Streams.
