Dynamo To Cognito

User Migration

Migrates user accounts securely from AWS DynamoDB to AWS Cognito using the UserMigration_Authentication Lambda trigger.

Password Hash Comparison

Uses bcrypt to verify user passwords during migration, ensuring a secure authentication process.

User Authentication

Provides features like sign-up, sign-in, account verification, and a responsive user dashboard.

AWS Service Integration

Demonstrates seamless integration of AWS DynamoDB, AWS Cognito, and AWS Lambda for a full-stack cloud-based solution.

Responsive Design

Ensures pages are fully responsive, providing a seamless experience across devices.

Password Migration Challenges

Ensuring bcrypt compatibility between the old and new systems required careful debugging and validation to guarantee accuracy.

Lambda Trigger Configuration

Configuring the UserMigration_Authentication Lambda trigger to work seamlessly with Cognito and DynamoDB required extensive testing and refinement.

Lack of Unit Tests

The absence of unit tests posed challenges in validating edge cases, highlighting the need for future improvements in testing coverage.

Importance of Secure Password Handling

Learning how to securely hash and verify passwords using bcrypt emphasized the significance of strong authentication practices.

Leveraging AWS Services

This project deepened my understanding of AWS services like Cognito, DynamoDB, and Lambda, and how to integrate them for cloud-based solutions.

Scalable System Design

Designing a migration system that scales with growing user bases taught me the importance of clean and efficient code architecture.
