From Static Storage to Managed Databases: Learning Amazon RDS, DynamoDB & AWS Lambda (Day 5)

When I started learning cloud engineering, I believed infrastructure was mostly about launching servers and hosting applications. In the past few days, that perspective has changed significantly. On Day 3, I deployed a web application on a Linux server using Amazon EC2 and Nginx. On Day 4, I hosted a static website using Amazon S3 without running a server at all. Today’s learning introduced another important part of cloud architecture: Databases and serverless computing. I explored how applications store and process data using: - Amazon RDS - Amazon DynamoDB - AWS Lambda These services showed me how AWS enables developers to build scalable backend systems without managing infrastructure manually. 🚀 The Objective Today’s goal was to understand how cloud applications manage and process data. The focus areas were: Deploying a managed relational database Connecting an application server to the database Learning NoSQL database architecture Executing backend logic using
