Serverless Data Pipeline (AWS Lambda + DynamoDB)
Why Choose This Project?
In the age of real-time analytics, IoT, and distributed systems, traditional server-based data processing can be costly and inefficient. This project demonstrates how to build a fully serverless, scalable, and event-driven pipeline using AWS Lambda and DynamoDB.
Ideal for students who want to explore cloud-native, event-driven architectures, and cost-effective serverless computing. It eliminates infrastructure overhead while enabling scalable ingestion and processing of data streams in real time.

Role-based access using IAM
-
Scalable architecture for any number of requests/events
-
Optional: Integrate with Amazon S3, Kinesis, or SNS for extended capabilities
Technology Stack
Layer | Technology Used |
---|---|
Backend Logic | AWS Lambda (Node.js or Python) |
API Gateway | AWS API Gateway |
Database | AWS DynamoDB (NoSQL, highly scalable) |
Security | AWS IAM (for role-based Lambda execution) |
Monitoring | AWS CloudWatch |
Optional | Amazon S3, AWS SNS/SQS, Kinesis |
Architecture Workflow
-
User or device sends data (e.g., IoT sensor data, app event logs) via a REST API.
-
AWS API Gateway receives the request and routes it to AWS Lambda.
-
Lambda function validates, parses, and transforms the data.
-
The processed data is then stored in DynamoDB.
-
CloudWatch logs and metrics monitor failures, latency, and execution time.
-
Optional: Add Lambda triggers for downstream processing (e.g., alerts via SNS, archiving to S3).
Security Best Practices
-
Use IAM roles and policies to restrict access to Lambda and DynamoDB
-
Validate incoming payloads in Lambda to avoid injection attacks
-
Set rate limits and CORS rules in API Gateway
-
Enable CloudWatch alarms for unusual activity or failures
Real-World Use Cases
-
IoT sensor data ingestion
-
User activity tracking in web/mobile apps
-
Form submissions with audit logs
-
Logging events from distributed apps
-
Real-time analytics foundation
