Advanced DynamoDB Modeling for Realtime Matchmaking - Zero Cost Architecture

#dynamodb  #aws  #api-gateway  #system-design  #overloading-pattern 

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.
