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!
