AWS Eventbridge Scenario based Questions ❓

❓Your application needs to react to changes in S3 buckets. How can you use EventBridge to automatically trigger a Lambda function whenever an object is uploaded to a specific S3 bucket?

Answer: Configure S3 to send events to EventBridge for object uploads. Create an EventBridge rule to match the S3 event pattern and set the Lambda function as the target.

❓You have multiple microservices in your application, and you need to ensure they can communicate asynchronously using events. How can EventBridge help you achieve this?

Answer: Use EventBridge as a central event bus where each microservice can publish events and create rules to route these events to the appropriate microservices’ targets.

❓You need to route events from a third-party SaaS application to your AWS Lambda function for processing. What steps do you need to take to set this up in EventBridge?

Answer: Configure the third-party SaaS application to send events to EventBridge using a partner event source. Create an EventBridge rule to match the incoming events and set the Lambda function as the target.

❓Your company requires logging of all event patterns that do not match any existing rules for auditing purposes. How can you achieve this with EventBridge?

Answer: Create a catch-all rule with an event pattern that matches all events and set the target to an S3 bucket or a logging service like CloudWatch Logs.

❓You need to ensure that certain critical events are processed in a specific order. How can you use EventBridge to handle this requirement?

Answer: Use EventBridge’s archive and replay feature to store events and then replay them in the required order. Alternatively, consider using AWS Step Functions to orchestrate event processing with specific ordering.

❓Your application generates custom events, and you want to store these events in Amazon S3 for future analysis. How can you configure EventBridge to achieve this?

Answer: Create a custom event bus to receive the custom events. Set up an EventBridge rule to match these events and set an S3 bucket as the target.

❓You want to integrate EventBridge with an on-premises application to trigger actions based on certain events. What approach can you use?

Answer: Use EventBridge to send events to AWS Lambda or an SNS topic, which can then use AWS Systems Manager or AWS Direct Connect to interact with the on-premises application.

❓Your application needs to send a notification via SNS whenever a specific CloudTrail event occurs. How can you set up EventBridge to handle this?

Answer: Configure CloudTrail to send events to EventBridge. Create an EventBridge rule to match the specific CloudTrail event pattern and set the SNS topic as the target.

❓You need to ensure that if an event fails to be processed by its target, it is retried or logged for troubleshooting. How can EventBridge help you manage this?

Answer: Use a dead-letter queue (DLQ) to capture failed events. Configure EventBridge rules with a DLQ target, such as an SQS queue, to handle failed event processing.

❓Your application requires processing of events based on specific attributes within the event payload. How can you set up EventBridge rules to filter events by these attributes?

Answer: Create EventBridge rules with event patterns that match the specific attributes within the event payload, and set the appropriate targets for these filtered events.

❓You need to route events from different environments (e.g., dev, staging, production) to separate targets. How can you use EventBridge to manage this?

Answer: Create separate custom event buses for each environment. Configure your applications to send events to the appropriate event bus based on the environment.

❓ You want to implement a multi-region failover for your EventBridge event processing to ensure high availability. What feature of EventBridge can you use?

Answer: Use EventBridge Global Endpoints to configure failover between primary and secondary event buses across different AWS regions.

❓Your team needs to share event schemas across multiple AWS accounts. How can EventBridge help with this?

Answer: Use the EventBridge Schema Registry to create and manage event schemas. Share the schemas with other AWS accounts by granting appropriate permissions.

❓ You need to process high-frequency events from a Kinesis Data Stream and send them to different targets based on event content. How can you achieve this with EventBridge?

Answer: Create an EventBridge rule with a Kinesis Data Stream as the event source. Define event patterns to filter the events based on content and route them to different targets.

❓ Your application requires an event-driven workflow that involves multiple steps, each triggered by different events. How can you use EventBridge to orchestrate this workflow?

Answer: Combine EventBridge with AWS Step Functions to create an event-driven workflow. Use EventBridge rules to trigger Step Functions based on specific events and define state machines to handle the workflow steps.
