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.

Step 4 – optimize

Now, with everything we need on Google Cloud we are ready to optimize our workloads and applications to make the most out of Google Cloud's services.

The first step of optimizing your applications is to set your optimization goals. Your optimizations goals can be very specific or broader and generally focused around Google Cloud's benefits, such as improving performance and scaling, making the infrastructure more resilient, increasing automation, reducing costs, and so on.

Once you have set your goals and a baseline has been established (to compare future performance to later), we can get started with optimization.

Letting internal teams takeover

As an independent developer or consultant, you're probably not going to take over your client's day-to-day operations. So, at this point in the migration, it's a good idea to start thinking about training internal or in-house teams.

Some of your main goals would be to do the...
