Building a Simple Student Attendance Tracker with AWS
A simple Cloud-Based Student Attendance Tracker built using AWS to help teachers record and view attendance online. The project uses Amazon DynamoDB for storing records and AWS Lambda for the backend logic. It demonstrates how serverless cloud services can provide an easy, scalable, and low-cost solution for everyday record keeping.
Building a Simple Student Attendance Tracker with AWS ☁️📋 :
Teachers often record attendance in paper registers or separate spreadsheets, which makes it hard to search, correct, and keep safe. To solve this problem, I explored a simple Cloud-Based Student Attendance Tracker using AWS. The project allows teachers to mark attendance and view it online from any device. Amazon DynamoDB can be used to store each attendance record, such as the student name, date, and status. A simple HTML and CSS interface can be used for the frontend, while AWS Lambda can handle the backend logic and connect the application with the database through Amazon API Gateway. The teacher selects a student and marks present or absent, the application sends the request to Lambda, and the record is saved in DynamoDB and can be viewed whenever needed. IAM roles keep the system secure by giving Lambda access only to the attendance table.
This small project helped me understand basic concepts such as serverless computing, NoSQL databases, REST APIs, and secure access between AWS services. In the future, features like teacher login with Amazon Cognito, monthly attendance reports, email alerts for low attendance using Amazon SNS, and a website hosted on Amazon S3 can be added. This project shows how AWS and cloud technology can make everyday school tasks simpler, faster, and more reliable.

Explanation
Teacher's web page: The teacher opens a simple HTML/CSS page, picks a student, and marks present or absent.
API Gateway: The page sends the request here. It acts as the front door and routes each request (save attendance, view attendance) to the right function.
AWS Lambda: Runs your backend code only when a request arrives. It checks the data, then reads from or writes to the database. There is no server to manage.
Amazon DynamoDB: Stores each record (student name, date, status). It is fast, scales automatically, and needs no database server.
IAM role: Gives Lambda permission to use only the attendance table and nothing else. This is the least-privilege rule.
Example flow: The teacher marks "Priya: Present" → API Gateway receives it → Lambda saves it → DynamoDB stores it → the teacher sees a success message.
