BUILDING AN EVENT DRIVEN GAME NOTIFICATION APP

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.

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.
