USE CASE
I was tasked with designing a Games Notification system, leveraging a serverless architecture. The solution utilizes an AWS Lambda function, integrates with an external API for data retrieval, and employs Amazon Simple Notification Service(SNS) for disseminating notifications.

PREREQUISITES

• AWS free tier account

• Knowledge on serverless service

• python

DEFINITION OF SERVICES.

• AWS Lambda Function: It enables seamless code execution without requiring manual infrastructure configuration.

• Simple Notification Service: It enables the delivery of notifications to subscribed endpoints, such as email addresses, phone numbers, or application endpoints.

• Event Bridge: It serves as a scheduler and event bus, triggering the Lambda function at specified intervals.

Amazon Simple Notification Service (SNS)
Let's create the SNS that will serve as a notification.

Kindly leaves everything at default and create topic.
Next, is to create subscription so as to allow it to send to our email.

Lambda Function
Firstly, let's create IAM role for the Lambda function to define its permissions and access to AWS services.

Now let's create our Lambda function since we have created our policies and role.

API KEY
I was able to get the free API key from https://sportsdata.io/cart/free-trial-confirmation/nba

Code testing has been completed successfully, and the SNS has sent a confirmation email as expected.

EVENTBRIDGE
Now, let's configure EventBridge to schedule the game notifications, ensuring timely and automated delivery.

Conclusion

We have successfully implemented a game notification system utilizing a serverless architecture, leveraging AWS Lambda, Amazon SNS, and EventBridge. The system integrates with an external API using Python, enabling seamless notification delivery to users.
