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 learned about Google Cloud Run and Knative, the open source project it is built upon. We learned that Google Cloud Run is a serverless platform for hosting our container-based microservices, and a key design goal is to remove the boring but difficult parts of deploying microservices, such as configuring Horizontal Pod Autoscalers, Services, and Ingress. We learned how to automatically deploy our microservices to Google Cloud Run using a custom domain name.

Deploying apps with Cloud Run is one of the easiest ways to future-proof your application. It also helps ensure that the apps you develop can stand the test of time and continue to live on within the fast-changing world of cloud-native. That said, Cloud Run still has its limitations, especially when it comes to complex orchestration. Thankfully, as with almost everything else that the cloud and Google Cloud offer, there are alternatives to future-proofing your app, too.

And finally, we would like...
