Find out for yourself with Rails: Up and Running, the concise and popular book that not only explains how Rails works, but guides you through a complete test drive. Perfect for beginning web developers, this thoroughly revised edition teaches you the basics of installing and using Rails 2.1 and the Ruby scripting language. While Rails is praised for its simplicity, there are still a few tricky steps to master along the way. Rails: Up and Running offers lots of examples and covers just about everything you need to build functional Rails applications right away. Learn how to: Create simple database-backed applications, and build dynamic user-centric web pages using Ajax and REST Exploit the Rails service frameworks to send emails and implement web services Map data to an imperfect table, traverse complex relationships, and build custom finders Use techniques to solve common database performance problems See how fast you can go on Rails, and how reliable it's become with the stability and power of version 2.1. With Rails: Up and Running, you'll discover why Rails is a remarkable new way to build database-driven web applications.

Ruby on Rails is the super-productive new way to develop full-featuredweb applications. With Ruby on Rails, powerful web applications thatonce took weeks or months to develop can now be produced in a matter ofdays. If it sounds too good to be true, it isn't. If you're like a lot of web developers, you've probably consideredkicking the tires on Rails - the framework of choice for the newgeneration of Web 2.0 developers. Ruby on Rails: Up and Running takes you out for a test drive and shows you just how fastRuby on Rails can go. This compact guide teaches you the basics of installing and using boththe Ruby scripting language and the Rails framework for the quickdevelopment of web applications. Ruby on Rails: Up andRunning covers just about everything youneed - from making a simple database-backed application toadding elaborate Ajaxian features and all the juicy bits in between.While Rails is praised for its simplicity and speed of development,there are still a few steps to master on the way. More advancedmaterial helps you map data to an imperfect table, traverse complexrelationships, and build custom finders. A section on working with Ajaxand REST shows you how to exploit the Rails service frameworks to sendemails, implement web services, and create dynamic user-centric webpages. The book also explains the essentials of logging to findperformance problems and delves into other performance-optimizingtechniques. As new web development frameworks go, Ruby on Rails is the talk of thetown. And Ruby on Rails: Up and Running can makesure you're in on the discussion.

Legend has it that Google deploys over two billion application containers a week. How’s that possible? Google revealed the secret through a project called Kubernetes, an open source cluster orchestrator (based on its internal Borg system) that radically simplifies the task of building, deploying, and maintaining scalable distributed systems in the cloud. This practical guide shows you how Kubernetes and container technology can help you achieve new levels of velocity, agility, reliability, and efficiency. Authors Kelsey Hightower, Brendan Burns, and Joe Beda—who’ve worked on Kubernetes at Google and other organizatons—explain how this system fits into the lifecycle of a distributed application. You will learn how to use tools and APIs to automate scalable distributed systems, whether it is for online services, machine-learning applications, or a cluster of Raspberry Pi computers. Explore the distributed system challenges that Kubernetes addresses Dive into containerized application development, using containers such as Docker Create and run containers on Kubernetes, using the docker image format and container runtime Explore specialized objects essential for running applications in production Reliably roll out new software versions without downtime or errors Get examples of how to develop and deploy real-world applications in Kubernetes

In just five years, Kubernetes has radically changed the way developers and ops personnel build, deploy, and maintain applications in the cloud. With this book's updated third edition, you'll learn how this popular container orchestrator can help your company achieve new levels of velocity, agility, reliability, and efficiency--whether you're new to distributed systems or have been deploying cloud native apps for some time. Brendan Burns, Joe Beda, Kelsey Hightower, and Lachlan Evenson--who have worked on Kubernetes at Google and beyond--explain how this system fits into the life cycle of a distributed application. Software developers, engineers, and architects will learn ways to use tools and APIs to automate scalable distributed systems for online services, machine learning applications, or even a cluster of Raspberry Pi computers. This guide shows you how to: Create a simple cluster to learn how Kubernetes works Dive into the details of deploying an application using Kubernetes Learn specialized objects in Kubernetes, such as DaemonSets, jobs, ConfigMaps, and secrets Explore deployments that tie together the lifecycle of a complete application Get practical examples of how to develop and deploy real-world applications in Kubernetes
