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.

Implementing an outbound External Service Gateway

In the Implementing an inbound External Service Gateway recipe, we discussed how the ESG pattern provides an anti-corruption layer between the cloud-native system and its external dependencies. In this recipe, we will create an ESG service that allows events to flow outbound to an external service. The single responsibility of this service is to encapsulate the details of the external system. The service applies the CQRS pattern. The internal events are transformed to the external format and forwarded to the external system via its API.

Getting ready

Before starting this recipe, you will need an AWS Kinesis Stream, such as the one created in the Creating an event stream recipe...
