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.

Summary

In this chapter, we've covered Google Cloud's suite of IAM services and how they can be used to create effective boundaries for access and ensure that individuals who need to stay out, stay out. Cloud IAM sits at the core of these services and does everything an IAM platform needs to do. However, with changing requirements such as remote working, developers may need to expand on their security capabilities. For this, we have new solutions and methods such as context-based conditions and BeyondCorp.

With this chapter, we've reached the end of the first part of this book. So far, we've learned about the various concepts and components involved in cloud-native infrastructure. We've also taken an in-depth look at the various services in the Google Cloud ecosystem and how we can use them together and leverage their strengths to create the app we want.

The upcoming chapters mark the start of the second part of this book, where we will begin creating...
