The practice of decoupling deployment from release is predicated on the use of feature flags. We are continuously deploying small batches of change to mitigate the risks of each deployment. These changes are deployed all the way to production, so we need a feature flag mechanism to disable these capabilities until we are ready to release them and make them generally available. We also need the ability to enable these capabilities for a subset of users, such as beta users and internal testers. It is also preferable to leverage the natural feature flags of a system, such as permissions and preferences, to minimize the technical debt that results from littering code with custom feature flags. This recipe will show you how to leverage the claims in a JWT token to enable and disable features.

Overview of this book
Cloud-native development is a modern approach to building and running applications that leverages the merits of the cloud computing model. With cloud-native development, teams can deliver faster and in a more lean and agile manner as compared to traditional approaches. This recipe-based guide provides quick solutions for your cloud-native applications.
Beginning with a brief introduction, JavaScript Cloud-Native Development Cookbook guides you in building and deploying serverless, event-driven, cloud-native microservices on AWS with Node.js. You'll then move on to the fundamental patterns of developing autonomous cloud-native services and understand the tools and techniques involved in creating globally scalable, highly available, and resilient cloud-native applications. The book also covers multi-regional deployments and leveraging the edge of the cloud to maximize responsiveness, resilience, and elasticity.
In the latter chapters you'll explore techniques for building fully automated, continuous deployment pipelines and gain insights into polyglot cloud-native development on popular cloud platforms such as Azure and Google Cloud Platform (GCP). By the end of the book, you'll be able to apply these skills to build powerful cloud-native solutions.
