Download or read book Deploying with JRuby 9k written by Joe Kutner and published by Pragmatic Bookshelf. This book was released on 2016-07-19 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deploy using the JVM's high performance while building your apps in the language you love. This book introduces you to three JRuby deployment strategies that give you the performance and scalability you need, while you use a language designed for rapid development. Explore common deployment scenarios, including consolidating an MRI-based Ruby deployment onto a single JVM process and porting a Rails application to JRuby, getting it into production, and keeping it running. This new edition has new chapters on Puma, performance tuning, and Java integration, and is updated to the latest versions of JRuby 9k, Rails 4, and JDK 8. JRuby is a fast, scalable, and powerful JVM language with all the benefits of a traditional Ruby environment. JRuby deployments have fewer moving parts and consume less memory than traditional Ruby. With this book, you can now use JRuby in the real world to build high-performance, scalable applications. Deploying your apps on the JVM requires some new approaches. Start by creating a JRuby microservice that takes advantage of the JVM's native concurrency. Then use Docker to build a virtual production environment that's a stable, reproducible place to explore JRuby deployment. Next, port an existing Rails application to JRuby, preparing the app to take advantage of the JVM platform--all while keeping everything that's friendly and familiar to Ruby developers. Deploy the Rails app to Docker with a multi-threaded Puma server to Heroku or your own private cloud. Take advantage of powerful Java libraries. See how JRuby fits into the enterprise by switching your app to use TorqueBox, an all-in-one JRuby environment that includes built-in support for messaging, scheduling, and daemons--perfect for handling the big jobs. Finally, take a deep dive into JVM performance tuning and set up a continuous deployment environment with Travis CI. What You Need: To run the examples in this book, you'll need a computer that can run the Java Virtual Machine and a connection to the Internet.

Download or read book Ruby in Practice written by Jeremy McAnally and published by Simon and Schuster. This book was released on 2009-02-28 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruby in Practice increases your productivity by showing you specific Ruby techniques you can use in your projects. The book offers detailed strategies for using Ruby in a large-scale environment. You'll see concrete examples of integration, messaging, web development, and databases, all presented in a clear Problem/Solution format. This book won't help you push your deadline back, but it will help you get the job done in less time. Above all, Ruby in Practice is a practical book for developers who want an in depth understanding of the Ruby language and its toolset. The book is divided into three major parts. The first part concentrates on issues that developers face both from within their organizations and from their peers. The authors weigh the costs and benefits of using Ruby in enterprise development projects, the over-riding theme being that every developer should always aim to use the right tool for any particular job. The authors then examine the pros and cons of developing with Ruby, and where appropriate, compare Ruby to other languages, both conceptually and in code. The second part discusses techniques for communication and integration of systems. The authors describe how libraries and techniques are used to facilitate messaging, web development and communication automation. They also focus on how the strategies in the first section can be used with these libraries to make development more flexible and efficient. The last part shows how to manage data and integrate with existing data using Ruby. The authors describe techniques for using existing Ruby libraries that either replace popular Java libraries or can interface with existing data in a different way. They go on to show you how strategies covered in the first section can be used to enable Ruby to interact with existing assets or to build new data systems. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.

Download or read book Programming Concurrency on the JVM written by Venkat Subramaniam and published by Pragmatic Bookshelf. This book was released on 2011-08-26 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than ever, learning to program concurrency is critical to creating faster, responsive applications. Speedy and affordable multicore hardware is driving the demand for high-performing applications, and you can leverage the Java platform to bring these applications to life. Concurrency on the Java platform has evolved, from the synchronization model of JDK to software transactional memory (STM) and actor-based concurrency. This book is the first to show you all these concurrency styles so you can compare and choose what works best for your applications. You'll learn the benefits of each of these models, when and how to use them, and what their limitations are. Through hands-on exercises, you'll learn how to avoid shared mutable state and how to write good, elegant, explicit synchronization-free programs so you can create easy and safe concurrent applications. The techniques you learn in this book will take you from dreading concurrency to mastering and enjoying it. Best of all, you can work with Java or a JVM language of your choice - Clojure, JRuby, Groovy, or Scala - to reap the growing power of multicore hardware. If you are a Java programmer, you'd need JDK 1.5 or later and the Akka 1.0 library. In addition, if you program in Scala, Clojure, Groovy or JRuby you'd need the latest version of your preferred language. Groovy programmers will also need GPars.

Download or read book Spring Recipes written by Gary Mak and published by Apress. This book was released on 2010-12-28 with total page 1091 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Spring framework is growing. It has always been about choice. Java EE focused on a few technologies, largely to the detriment of alternative, better solutions. When the Spring framework debuted, few would have agreed that Java EE represented the best-in-breed architectures of the day. Spring debuted to great fanfare, because it sought to simplify Java EE. Each release since marks the introduction of new features designed to both simplify and enable solutions. With version 2.0 and later, the Spring framework started targeting multiple platforms. The framework provided services on top of existing platforms, as always, but was decoupled from the underlying platform wherever possible. Java EE is a still a major reference point, but it’s not the only target. OSGi (a promising technology for modular architectures) has been a big part of the SpringSource strategy here. Additionally, the Spring framework runs on Google App Engine. With the introduction of annotation-centric frameworks and XML schemas, SpringSource has built frameworks that effectively model the domain of a specific problem, in effect creating domain-specific languages (DSLs). Frameworks built on top of the Spring framework have emerged supporting application integration, batch processing, Flex and Flash integration, GWT, OSGi, and much more.
