In Detail

Today's world is all about perfection, and there are hundreds of applications that are released each day out of which only a few succeed. Making sure that the app looks, performs, and behaves as expected is one of the biggest challenge developers face today.

The main goal of this book is to teach developers to implement DevOps to build, test, and deliver. This book will teach you to implement Mobile DevOps at every stage of your application's lifecycle with Visual Studio and Xamarin Mobile Lifecycle solutions. Later, it will also show you how to leverage Mobile Center's continuous integration and automated testing to develop a high-quality applications. Next, you'll see how to mobilize your on-premises data to the cloud and increase your productivity with code reuse. Finally, you'll discover how to find and fix bugs beforehand, improving the efficiency of your application while it is being developed.

By the end of this book, you will be well-versed with Mobile DevOps techniques, delivering high quality and high performance mobile apps.

Style and approach

This clear, concise, and straightforward book will make you aware of mobile applications by showing you Devops fundamentals such as building, testing, and delivery. This book has been created to help you put new ideas into practice, and demonstrate precisely what's possible with mobile Devops.
