A delivery company is running a serverless solution in tneAWS Cloud The solution manages user data, delivery information and past purchase details The solution consists of several microservices The central user service stores sensitive data in an Amazon DynamoDB table Several of the other microservices store a copy of parts of the sensitive data in different storage services
The company needs the ability to delete user information upon request As soon as the central user service deletes a user every other microservice must also delete its copy of the data immediately
Which solution will meet these requirements?
Set Up EventBridge Event Bus:
Step 1: Open the Amazon EventBridge console and create a custom event bus. This bus will be used to handle user deletion events.
Step 2: Name the event bus appropriately (e.g., user-deletion-bus).
Post Events on User Deletion:
Step 1: Modify the central user service to post an event to the custom EventBridge event bus whenever a user is deleted.
Step 2: Ensure the event includes relevant details such as the user ID and any other necessary metadata.
Create EventBridge Rules for Microservices:
Step 1: For each microservice that needs to delete user data, create a new rule in EventBridge that triggers on the user deletion event.
Step 2: Define the event pattern to match the user deletion event. This pattern should include the event details posted by the central user service.
Invoke Microservice Logic:
Step 1: Configure the EventBridge rule to invoke a target, such as an AWS Lambda function, which contains the logic to delete the user data from the microservice's data store.
Step 2: Each microservice should have its Lambda function or equivalent logic to handle the deletion of user data upon receiving the event.
Using Amazon EventBridge ensures a scalable, reliable, and decoupled approach to handle the deletion of user data across multiple microservices. This setup allows each microservice to independently process user deletion events without direct dependencies on other services.
