DESCRIPTION Although Spring Framework simplifies enterprise Java development, it can require a lot from developers in terms of framework configuration. Spring Boot radically streamlines the process of creating Spring applications by employing automatic configuration, along with a programming model built around established conventions for build-time and runtime dependencies. It also provides a component that gives insight into the internals of a running application and a handy CLI that can be used to write command-line scripts in Groovy. Developers who have used Spring Boot say that they can't imagine ever going back to hand-configuring their applications. Spring Boot in Action is a developer-focused guide to writing applications using Spring Boot. It shows readers how to bypass the tedious configuration steps so that they can concentrate on their application's behavior. Using interesting, relevant examples, Spring expert Craig Walls shows both how to use the default settings effectively and how to override and customize Spring Boot for each unique environment. Along the way, it offers insights from Craig's years of Spring development experience. KEY SELLING POINTS Practical hands-on guide Quickly develop Spring applications Author insights based on years of Spring Development Covers newest features of Spring Boot AUDIENCE Written for readers familiar with the Spring Framework. ABOUT THE TECHNOLOGY Spring Boot brings a convention-over-configuration programming model to the Spring Framework. With Spring Boot, Spring developers can focus on producing application functionality with little effort spent on configuring Spring itself.

DevOps for Developers delivers a practical, thorough introduction to approaches, processes and tools to foster collaboration between software development and operations. Efforts of Agile software development often end at the transition phase from development to operations. This book covers the delivery of software, this means the last mile, with lean practices for shipping the software to production and making it available to the end users, together with the integration of operations with earlier project phases (elaboration, construction, transition). DevOps for Developers describes how to streamline the software delivery process and improve the cycle time (that is the time from inception to delivery). It will enable you to deliver software faster, in better quality and more aligned with individual requirements and basic conditions. And above all, work that is aligned with the DevOps approach makes even more fun * Provides patterns and toolchains to integrate software development and operations * Delivers an one-stop shop for kick-starting with DevOps * Provides guidance how to streamline the software delivery process What you'll learn * Know what DevOps is and how it can result in better and faster delivered software * Apply patterns to improve collaboration between development and operations * Introduce unified processes and incentives to support shared goals * Start with or extend a tool infrastructure that spans projects roles and phases * Address pain points in your individual environment with appropriate recipes * Break down existing walls that make up an unnecessarily sluggish delivery process Who this book is for DevOps for Developers is for motivated software engineers, particularly programmers, testers, QA, system admins, database admins, both beginners and experts, who want to improve their software delivery process. It's the perfect choice for engineers who want to go the next step by integrating their approaches for development and delivery of software.This book is for engineers who want to shape their processes and decide on and integrate open source tools and seek for guidance how to integrate standard tools in advanced real world use cases.

DESCRIPTION Serverless architecture is about having more time to focus on code, and moving quickly. In these new architectures, traditional back-end servers are replaced with cloud functions acting as discrete singlepurpose services. With serverless compute technologies like AWS Lambda, developers can build entirely serverless platforms at scale. Serverless Architectures on AWS teaches how to build, secure and manage serverless architectures that can power the most demanding web and mobile apps. This book has many ready-made and real-world examples, code snippets, diagrams, and descriptions of architectures that can be readily applied. It describes a traditional application and its back end concerns and then shows how to solve these same problems with a serverless approach. By the end, readers will be able to reason about serverless systems and be able to compose their own systems by applying these ideas and examples. KEY FEATURES * Up-to-date with the most current platform trends * Real-world examples, code snippets, and diagrams * Learn to solve back end concerns with a serverless approach AUDIENCE This book is for all software developers interested in back end technologies. Experience with JavaScript (node.js) and AWS is useful but not required. ABOUT THE TECHNOLOGY Lambda is a compute service that executes code written in JavaScript (node.js), Python, or Java on AWS infrastructure. Source code is deployed to an isolated container that has its own allocation of memory, disk space, and CPU. Serverless architectures herald a new way of building scalable, powerful, cost-effective, and high-performing back end systems. They encourage a new way of creating applications through the use of a stateless compute service to execute code.
