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 alerts

To maximize our confidence in our cloud-native services, we need to be alerted about issues ahead of the end users so that we can respond quickly and minimize the mean time to recovery. This also means that we need to eliminate alert fatigue and only alert on what really matters, otherwise important alerts will be lost in the noise. This recipe demonstrates how to create alerts on key metrics.

How to do it...

  1. Log in to your Datadog account.
  2. Create an IAM alert with the following settings:
    • Select Monitors | New Monitor | Event
    • Match events from Amazon Cloudtrail over aws-service:iam
    • Multi Alertaws_account
    • Alert thresholdabove 0
    • Titleaws.iam
    • Include trigger tagstrue
    • Notify—...
