The Web is slowly but surely changing from a model in which a human reader browses content on web pages to a model in which services and clients (not necessarily humans) exchange information. And because of this, author Silvia Puglisi explains, it makes more sense to build platforms instead of just products or applications. Platforms are like ecosystems interconnecting different applications, services, users, developers, and partners, and offer many benefits.

In this book, you´ll learn how to design and develop Representational State Transfer (REST) platforms in Rails. You´ll begin with an introduction to Ruby on Rails, and then move quickly through new concepts. At the end of each chapter, you´ll have learned something new about building and organically extending a multi-service platform spanning different devices-and will have had some fun in the process. By the end of the book you´ll know how to build an architecture composed of different services accessing shared resources through a set of collaborating APIs and applications.
