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.

In this blog, I will indicate some key points required to return to optimal agile performance. I will highlight three common pitfalls, some common causes of those problems, and reminders of how to get back to a high-performance Scrum implementation. Let’s dive in.

As with any technology, you start to notice that a few of the pages are looking a little slow. You know performance tuning too early is often a bad idea, but you feel like you might be at that point. After all, in your experience, end users notice even small lags and no one wants that. So what do you do now?

In this blog, I introduce six tips for improving performance and design in your React application.
