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.

Google Kubernetes Engine

Similar to Cloud Run, GKE is also a managed environment where you can run your applications, and like Cloud Run, we will dive deeper into the workings of GKE in subsequent chapters. But for now, we'll just understand GKE and how it fits into the cloud-native app development pipeline.

GKE provides developers with a managed environment where they can deploy and manage all of their containerized applications. Here, it is important to make a clear distinction between Cloud Run and GKE.

Both of these solutions help developers achieve the same goal – deploy and manage containerized applications – but Cloud Run is a fully managed service and will take care of a lot of things, making deployment faster and easier. Kubernetes, on the other hand, is an orchestration platform that provides far more flexibility and configuration options, allowing you to take control of everything.

Therefore, the platform you choose depends on how much control...
