JavaScript Cloud Native Development Cookbook

By: John Gilbert

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.

Creating a micro event store

In the Creating a data lake recipe, we will discuss how the Event Sourcing pattern provides the system with an audit trail of all the state-change events in the system. An event stream essentially provides a temporal event store that feeds downstream event processors in near real-time. The data lake provides a high durability, perpetual event store that is the official source of record. However, we have a need for a middle ground. Individual stream processors need the ability to source specific events that support their processing requirement. In this recipe, we will implement a micro event store in AWS DynamoDB that is owned by and tailored to the needs of a specific service.
