Enterprise Class Mobile Application Development: A Complete Lifecycle Approach for Producing Mobile Apps

by Leigh Williamson, Roland Barcia, Omkar Chandgadkar, Ashish Mathur, Soma Ray

Overview

 Build and Deploy Mobile Business Apps That Smoothly Integrate with Enterprise IT
For today’s enterprises, mobile apps can have a truly transformational impact. However, to maximize their value, you can’t build them in isolation. Your new mobile apps must reflect the revolutionary mobile paradigm and delight today’s mobile users--but they must also integrate smoothly with existing systems and leverage previous generations of IT investment.

In this guide, a team of IBM’s leading experts show how to meet all these goals. Drawing on extensive experience with pioneering enterprise clients, they cover every facet of planning, building, integrating, and deploying mobile apps in large-scale production environments. You’ll find proven advice and best practices for architecture, cloud integration, security, user experience, coding, testing, and much more.

Each chapter can stand alone to help you solve specific real-world problems. Together, they help you establish a flow of DevOps activities and lifecycle processes fully optimized for enterprise mobility.
