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.

Moving past third-party services – the beauty of end-to-end tooling

Developers building applications on traditional architectures and on-premises infrastructure would often use the help of third-party services to accelerate productivity. Using third-party services meant that developers wouldn't need to reinvent the wheel every time, saving a lot of time and also simplifying their workflows. But third-party services always had challenges: integration nightmares, lack of technical support, compatibility with other services, and limited scope were some of the top complaints.

Enter cloud platforms!

Cloud vendors such as Google Cloud have already created a huge ecosystem of services, giving developers the ability to build applications from start to finish without ever leaving the ecosystem – end-to-end tooling. They have all of the convenience of third-party services and none of the problems.

The following are some of the core benefits of end-to-end tooling...
