Many of today's applications need to be able to process large volumes of data, and vertical scaling has its limits both in terms of prohibitive cost and hardware limits. Gearman is an open source job manager that is well-suited to building horizontally scalable systems, from map-reduce algorithms to simple data processors capable of handling massive amounts of information.Instant Gearman is a practical, hands-on guide to getting started with building an open source job management server system that is built to grow. Learn the basics of building a distributed application that spans multiple components and learn how Gearman fits into building an application that scales from one to hundreds of components that interact to process data. With Gearman, you can build software that scales horizontally as your need for computation increases.Instant Gearman has in-depth examples and a step-by-step approach to building distributed systems, helping you to build systems that are scalable and modular in their approach to processing data.Once you are comfortable with building simple workers and clients, learn how to build a cluster of managers and see how to reduce single-point-of-failure in your architecture. Next, build a simple map-reduce application using Gearman and scale it up from a single instance to multiple parallel processing components.

Play is a full-featured Java and Scala web framework for building modern, high-performance web applications. It is characterized by its simplicity and scalability. With its lightweight, stateless, and web-friendly architecture, Play focuses on developer experience to make web application development fun.Instant Play Framework Starter is the ideal companion to start developing web applications with Play. The building blocks of a typical web application are carefully designed following an on-going example.Instant Play Framework Starter starts with a quick setup and running a first sample. Then, the anatomy of a typical Play application is outlined. More features are added step by step to an example application. The result is the prototype of a highly scalable web application.The example is implemented in Java and in Scala. It consists of building blocks you will find in every Play application. In particular, you will learn how views are rendered with the template engine, how HTTP routes are used to define the navigation rules, and how to separate the application logic of controllers from the business logic of the model. This separation is the result of a careful application design, which makes it easy to add features like data binding and validation. Finally you will see how easy it is to adapt different database access libraries.Instant Play Framework Starter will help you to get started with Play and develop your first application. Packed with examples, it is easy to follow the design of a real-world application. You are able to compare the difference between a Java- and a Scala-based Play application and to decide which language fits your needs best. All topics covered in the book are described with the aim to serve as a reference for future web application development with Play.
