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.

Appendix A: Choosing the Right Migration Strategy

In this book, we've explored numerous services and methodologies that achieve the same end goal: to bring a system onto Google Cloud Platform. To someone new, this complex web of interrelated technologies and practices might seem overkill. But there's a simple reason why we have a myriad of options instead of a single plug and play option – not every project is the same, but they are usually similar. For instance, as a developer, some of your projects might require you to migrate an application as quickly as possible or they might not have any deadlines at all; getting every function and feature onto the cloud is all that matters. So, in a way, we can group almost all cloud projects into broad categories that are defined by certain requirements. And to give more structure to development efforts, each cloud project category has an appropriate strategy that is usually the best way of getting started on the cloud. These...
