Creating machine images can be time-consuming and error-prone when done manually. HashiCorp Packer enables you to automate this process by defining the configuration in a simple, declarative syntax. This configuration is then used to create machine images for multiple environments and cloud providers.The book begins by showing you how to create your first manifest while helping you understand the available components. You’ll then configure the most common built-in builder options for Packer and use runtime provisioners to reconfigure a source image for desired tasks. You’ll also learn how to control logging for troubleshooting errors in complex builds and explore monitoring options for multiple logs at once. As you advance, you’ll build on your initial manifest for a local application that’ll easily migrate to another builder or cloud. The chapters also help you get to grips with basic container image options in different formats while scaling large builds in production. Finally, you’ll develop a life cycle and retention policy for images, automate packer builds, and protect your production environment from nefarious plugins.By the end of this book, you’ll be equipped to smoothen collaboration and reduce the risk of errors by creating machine images consistently and automatically based on your defined configuration.

Design patterns and idioms can widen our perspective byshowing us where to look, what to look at, and ultimatelyhow to see what we are looking at. At their best, patternsare a shorthand method of communicating better waysto code (writing less, more maintainable, and moreefficient code)This book starts with Haskell 98 and through the lens ofpatterns and idioms investigates the key advances andprogramming styles that together make modern Haskell.Your journey begins with the three pillars of Haskell.Then you'll experience the problem with Lazy I/O, togetherwith a solution. You'll also trace the hierarchy formedby Functor, Applicative, Arrow, and Monad. Next you'llexplore how Fold and Map are generalized by Foldableand Traversable, which in turn is unified in a broadercontext by functional Lenses. You'll delve more deeply intothe Type system, which will prepare you for an overviewof Generic programming. In conclusion you go to theedge of Haskell by investigating the Kind system andhow this relates to Dependently-typed programming

Haskell, with its power to optimize the code and its high performance, is a natural candidate for high performance programming. It is especially well suited to stacking abstractions high with a relatively low performance cost. This book addresses the challenges of writing efficient code with lazy evaluation and techniques often used to optimize the performance of Haskell programs. We open with an in-depth look at the evaluation of Haskell expressions and discuss optimization and benchmarking. You will learn to use parallelism and we'll explore the concept of streaming. We’ll demonstrate the benefits of running multithreaded and concurrent applications. Next we’ll guide you through various profiling tools that will help you identify performance issues in your program. We’ll end our journey by looking at GPGPU, Cloud and Functional Reactive Programming in Haskell. At the very end there is a catalogue of robust library recommendations with code samples.By the end of the book, you will be able to boost the performance of any app and prepare it to stand up to real-world punishment.
