Building Applications with Scala

Overview of this book

<p>Scala is known for incorporating both object-oriented and functional programming into a concise and extremely powerful package. However, creating an app in Scala can get a little tricky because of the complexity the language has. This book will help you dive straight into app development by creating a real, reactive, and functional application. We will provide you with practical examples and instructions using a hands-on approach that will give you a firm grounding in reactive functional principles.</p> <p>The book will take you through all the fundamentals of app development within Scala as you build an application piece by piece. We’ve made sure to incorporate everything you need from setting up to building reports and scaling architecture. This book also covers the most useful tools available in the Scala ecosystem, such as Slick, Play, and Akka, and a whole lot more. It will help you unlock the secrets of building your own up-to-date Scala application while maximizing performance and scalability.</p>

Preface

Adding the new UI introduction to Akka


Akka (http://akka.io/) is a framework to build concurrent, distributed, and resilient message-driven applications in Scala, Java, and .NET. Building applications with Akka has several advantages, which are as follows:

  • High performance: Akka delivers up to 50 million messages per second on a commodity hardware having ~2.5 million Actors per GB of RAM.

  • Resilient by design: Akka systems have self-healing properties for local and remote Actors.

  • Distributed and elastic: Akka has all the mechanisms to scale your application, such as cluster, load balancing, partitioning, and sharding. Akka lets you grow or shrink your Actors on demand.

The Akka framework provides good abstractions for concurrent, asynchronous, and distributed programming, such as Actors, Streams, and Futures. There are plenty of great success cases in production, such as BBC, Amazon, eBay, Cisco, The Guardian, Blizzard, Gilt, HP, HSBC, Netflix, and so many others.

Akka is a truly reactive framework...
