A company has a business intelligence platform on AWS. The company uses an AWS Storage Gateway Amazon S3 File Gateway to transfer files from the company's on-premises environment to an Amazon S3 bucket.
A data engineer needs to setup a process that will automatically launch an AWS Glue workflow to run a series of AWS Glue jobs when each file transfer finishes successfully.
Which solution will meet these requirements with the LEAST operational overhead?
To ensure the AWS Glue workflow is automatically launched with the least operational overhead when each file transfer completes, setting up an AWS Lambda function triggered by an S3 object creation event is the best solution. This approach leverages AWS's event-driven capabilities, triggering actions in real-time without manual intervention or scheduling estimations. It effectively bridges the action of the file transfer and the initiation of the workflow, ensuring seamless automation and efficient processing.
Using EventBridge directly to trigger the AWS Glue workflow upon S3 events is straightforward and leverages AWS's event-driven architecture, requiring minimal maintenance.
Event driven architecture with S3 file creation can only be EventBridge
Setting up an Amazon EventBridge event that initiates the AWS Glue workflow after every successful S3 File Gateway file transfer event would meet these requirements with the least operational overhead. This solution is event-driven and does not require manual intervention or reliance on a schedule that might not align with the actual completion time of the file transfers. The AWS Glue workflow is triggered automatically when a new file is added to the S3 bucket, ensuring that the AWS Glue workflow starts processing the new data as soon as it’s available.
The solution that will meet these requirements with the least operational overhead is Option D. Setting up an AWS Lambda function that will invoke the AWS Glue Workflow, and setting up an event for the creation of an S3 object as a trigger for the Lambda function, will ensure that the workflow is automatically initiated each time a file transfer is successfully completed. This approach requires minimal operational overhead as it automates the process and does not require manual intervention or scheduling based on estimated completion times. Options A and C involve manual intervention or assumptions about transfer times, which could lead to inefficiencies or inaccuracies. Option B is not feasible because Amazon EventBridge does not directly support triggering events based on S3 File Gateway file transfer events. Therefore, Option D is the most suitable solution.
Setting up an Amazon EventBridge event (Option B) to initiate the AWS Glue workflow after every successful S3 File Gateway file transfer event is the most efficient solution. It provides real-time automation with minimal operational overhead, ensuring that the Glue workflow starts immediately after the file transfer is complete.
