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

Cloud-native design patterns were made to help you anticipate and prevent common challenges in cloud-native app development. By having a strong understanding of these patterns, you can save a significant amount of time and effort by avoiding problems that are often faced by new developers. In a way, these patterns can be thought of as shortcuts but as with all shortcuts, they must be taken with caution. Design patterns aren't meant to be perfect; they're meant to be quick and widely applicable. As a result, they often come with certain drawbacks that, depending on your project, may not affect you at all or create more problems down the line. Therefore, it's very important to not just understand what problem a pattern is solving but also at what cost.

Armed with this knowledge, you are now ready to make your first big decision – choosing the compute option. Google Cloud offers a wide range of compute options and in the next chapter, we will discuss these...
