Building a Node.js Service with AWS Lambda, DynamoDB, and Serverless Framework

Matthew Brown Articles, AWS, Cloud, JavaScript, Node.js, Tutorial 3 Comments

My favorite new technology as a developer is serverless computing. The convenience and cost make it a very compelling choice for running options in the cloud. Especially for proof of concepts or quick ways to prove out ideas. Using serverless computing to get up and running takes very little effort and the costs of running an application in the cloud are minimal. Serverless really empowers developers to act on ideas as quickly as possible.

In this post, I’m going to briefly touch on what serverless computing is and the pros and cons of using it. Then I will build a Node.js service to do CRUD operations using AWS Lambda, DynamoDB, and the Serverless Framework. You can view the finished product on Github.

How to Prevent Retry Storms with Responsible Client-Side Retry Policies

Rachel Walker All Industries, Architecture, Articles, DevOps Leave a Comment

A retry storm occurs when large numbers of client applications retry failed requests simultaneously, spawning additional traffic that overwhelms already unstable systems.

While much of outage prevention rightly focuses on backend systemsโ€”load balancers, API gateways, circuit breakers, and queuesโ€”client-side retry policies play a critical but often overlooked role in system resiliency. Preventing retry storms requires treating client-side retry behavior as a core part of system resiliency.

In this article, weโ€™ll explore how retry storms form, how client applications unintentionally amplify traffic, and what development teams can do to implement safer, smarter retry behavior.
