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.

Leveraging asynchronous non-blocking IO

The design of a stream processor must account for the volume of data it will receive. The data should be processed in real-time and the processor should not fall behind. The following recipe demonstrates how to leverage asynchronous, non-blocking IO to process data in parallel to help ensure sufficient throughput.

How to do it...

Create the project from the following template:

$ sls create --template-url https://github.com/danteinc/js-cloud-native-cookbook/tree/master/ch9/frp-async-non-blocking-io --path cncb-frp-async-non-blocking-io

Navigate to the cncb-frp-async-non-blocking-io directory, cd cncb-frp-async-non-blocking-io.
Review the file named serverless.yml.
