The Definitive Guide to Modernizing Applications on Google Cloud: The what, why, and how of application modernization on Google Cloud (Paperback or Softback)

Get to grips with the tools, services, and functions needed for application migration to help you move from legacy applications to cloud-native on Google Cloud

Key Features

• Discover how a sample legacy application can be transformed into a cloud-native application on Google Cloud
• Learn where to start and how to apply application modernization techniques and tooling
• Work with real-world use cases and instructions to modernize an application on Google Cloud

Book Description

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.

What you will learn

• Discover the principles and best practices for building cloud-native applications
• Study the six Rs of migration strategy and learn when to choose which strategy
• Rehost a legacy enterprise application on Google Compute Engine
• Replatform an application to use Google Load Balancer and Google Cloud SQL
• Refactor into a single-page application (SPA) supported by REST services
• Replatform an application to use Google Identity Platform and Firebase Authentication
• Refactor to microservices using the strangler pattern
• Automate the deployment process using a CI/CD pipeline with Google Cloud Build

Who this book is for

This book is for software developers and solutions architects looking to gain experience in modernizing their enterprise applications to run on Google Cloud and transform them into cloud-native applications. Basic knowledge of Java and Spring Boot is necessary. Prior knowledge of Google Cloud is useful but not mandatory.
