Game Day Event Notification using AWS Serverless Services

This real-time NBA game score alert system delivers game day updates to subscribers via SMS or email. Leveraging AWS services like SNS, Lambda (Python), and EventBridge, along with the SportsData.io NBA API, it provides an efficient notification framework. This project showcases core cloud computing principles and best practices.

Key Features:

• Real-time NBA score retrieval using the SportsData.io API.
• Automated score updates sent via SMS/email using Amazon SNS.
• Scheduled updates managed by Amazon EventBridge.
• Robust security implemented with least privilege IAM roles.

System Architecture:

Technology Stack:

• Cloud Platform: AWS
• Core Services: Amazon SNS, AWS Lambda, Amazon EventBridge
• API: SportsData.io NBA Game API
• Programming Language: Python 3.x
• Security: Least privilege IAM policies for Lambda, SNS, and EventBridge.

Project Structure:

The project is organized as follows:

game-day-notifications/ ├── src/ │ ├── game_day_notifications.py # Main Lambda function ├── policies/ │ ├── game_day_sns.json # SNS publishing permissions │ ├── game_day_eventbridge_policy.json # EventBridge to Lambda permissions │ └── gd_lambda_policy.json # Lambda execution role permissions ├── .gitignore └── README.md # Project documentation

Deployment Steps:

1. Create an SNS Topic: Establish an SNS topic for sending notifications.
2. Configure SNS Subscriptions: Add email subscriptions to the topic and confirm them.
3. Create IAM Policies: Create and assign IAM policies (e.g., game_day_sns.json, game_day_eventbridge_policy.json, gd_lambda_policy.json) to grant the Lambda function necessary permissions to publish to SNS and interact with EventBridge.

4. Create an IAM Role for Lambda: Create an IAM role for the Lambda function, incorporating the necessary custom policies and the AWSLambdaBasicExecutionRole.

5. Deploy the Lambda Function: Deploy the game_day_notifications.py Lambda function and attach the newly created IAM role.

6. Configure EventBridge Automation: Set up an EventBridge rule to trigger the Lambda function at desired intervals.

7. Testing and Verification: Test the system and confirm notifications are successfully delivered to subscribers.

Project Output Examples:

Lessons Learned and Challenges:

• Successfully designed a notification system using AWS SNS and Lambda.
• Secured AWS services effectively using least privilege IAM policies.
• Automated workflows using EventBridge.
• Integrated an external API into a cloud-based workflow.

Challenges included handling errors related to API key retrieval from environment variables and Lambda execution timeouts.
