The Definitive Guide to Modernizing Applications on Google Cloud

By: Steve (Satish) Sangapu, Dheeraj Panyam, Jason Marston

Overview of this book

Legacy applications, which comprise 75–80% of all enterprise applications, often end up being stuck in data centers. Modernizing these applications to make them cloud-native enables them to scale in a cloud environment without taking months or years to start seeing the benefits. This book will help software developers and solutions architects to modernize their applications on Google Cloud and transform them into cloud-native applications. This book helps you to build on your existing knowledge of enterprise application development and takes you on a journey through the six Rs: rehosting, replatforming, rearchitecting, repurchasing, retiring, and retaining. You'll learn how to modernize a legacy enterprise application on Google Cloud and build on existing assets and skills effectively. Taking an iterative and incremental approach to modernization, the book introduces the main services in Google Cloud in an easy-to-understand way that can be applied immediately to an application. By the end of this Google Cloud book, you'll have learned how to modernize a legacy enterprise application by exploring various interim architectures and tooling to develop a cloud-native microservices-based application.

Cloud-native design patterns

Now that you have a clearer understanding of the common challenges of cloud-native app development, we can take a deeper look at cloud-native design patterns. Remember, there are hundreds of design patterns out there and this book cannot possibly detail every single one of them. So instead, we'll be focusing on some of the popular design patterns and the ones that are most relevant to you.

Microservices

This might seem redundant now that we're in the third chapter, but microservices are more than just basic criteria of cloud-native applications – they often form the basis of the solutions to a surprisingly large number of problems faced in cloud-native app development. In addition to keeping your microservices very loosely coupled and isolated, developers can follow a range of microservices principles and best practices that will be crucial in avoiding problems such as system-wide downtime, slow updates, lack of agility, and slow...
