Hello everyone. Welcome to the first part of distributed tracing with AWS XRay.

In this part, we are going to implement distributed tracing with X-Ray in a relatively complicated web application. I will be providing all of the required repositories, reference templates and screenshots to guide you through this process.

Background

Let me tell you a story. You have a web application written in ExpressJS and you have that deployed in AWS ECS and it communicates with RDS. The days were going good - but one day the QA team reports to you that some of the API endpoints are failing.

Hello all!

In this blog, I will share my journey with you - on how to create a scalable serverless application in AWS. We will be using completely serverless technologies like AWS Lambda, API Gateway, AWS DynamoDB etc. You can follow along with this guide and implement this app on your own and deploy in your own AWS account at no-cost. I did it all in free tier. I will be demonstrating complex overloading patterns in DynamoDB, API Gateway Websockets and some smart approaches on designing event driven web applications.
