**Workshop Name:Hands-on Workshop on Cloud-Native Systems & Applied AI** **Integration Organized by**: Department of Computing, Coimbatore Institute of Technology (Five Year Integrated Programme, M.Sc. AI & ML)

**Date:** 15 & 16 September 2026 (Tuesday & Wednesday) 

**Speaker:** Mr. Santhosh NC, Lead Infrastructure Consultant, Thoughtworks, Coimbatore

Session 2 picked up right where we left off — going deeper into EC2, moving files between EC2 and S3, and then stepping into the world of serverless computing with AWS Lambda. Here's the full recap!

**EC2: Connecting and Working with the Instance**

We continued exploring EC2 concepts and got hands-on with:

Opening the EC2 directory through Git Bash

Connecting to the EC2 instance using SSH

Working with AWS CLI commands, including checking the AWS CLI version

**IAM Roles**

We learned what IAM (Identity and Access Management) roles are and why they matter for securely granting permissions to AWS resources. As a hands-on activity, we created our own IAM roles.

Moving Data: Kaggle → EC2 → S3

To understand real-world data movement on AWS, we:

Downloaded a Kaggle dataset directly into the EC2 instance

Transferred the dataset from EC2 to S3

This gave us a practical feel for how data flows between compute and storage services on AWS.

Serverless Computing with AWS Lambda

Next, we were introduced to serverless computing and event-driven architecture using AWS Lambda:

Created a Lambda function and understood how it runs code automatically without needing to provision or manage any servers

Set up an S3 event trigger — so that whenever a file is uploaded to the S3 bucket, the Lambda function automatically gets triggered

**Monitoring with CloudWatch Logs**

Finally, we checked the latest trigger and execution details of our Lambda function using CloudWatch Logs, which helped us understand how to monitor and debug serverless workflows.

**Gratitude Note**

A huge thank you to our speaker, Mr. Santhosh NC, Lead Infrastructure Consultant at Thoughtworks, Coimbatore, for another insightful and hands-on session! Going from EC2 and CLI basics all the way to building an event-driven serverless pipeline with Lambda and S3 was a great way to see how AWS services connect in practice. Thanks also to the Department of Computing, CIT, and the organizing team — Dr. M. Sujithra (Convener), Dr. K. E. Hemapriya & Dr. R. Sudha (Faculty Coordinators), and Dr. K. Umamaheswari (Dean) — for organizing such a valuable session. Excited for what's next!
