A company's application integrates with multiple software-as-a-service (SaaS) sources for data collection. The company runs Amazon EC2 instances to receive the data and to upload the data to an Amazon S3 bucket for analysis. The same EC2 instance that receives and uploads the data also sends a noti cation to the user when an upload is complete. The company has noticed slow application performance and wants to improve the performance as much as possible.
Which solution will meet these requirements with the LEAST operational overhead?

A. Create an Auto Scaling group so that EC2 instances can scale out. configure an S3 event noti cation to send events to an Amazon Simple Noti cation Service (Amazon SNS) topic when the upload to the S3 bucket is complete.

B. Create an Amazon AppFlow flow to transfer data between each SaaS source and the S3 bucket. configure an S3 event noti cation to send events to an Amazon Simple Noti cation Service (Amazon SNS) topic when the upload to the S3 bucket is complete.

C. Create an Amazon EventBridge (Amazon CloudWatch Events) rule for each SaaS source to send output data. configure the S3 bucket as the rule's target. Create a second EventBridge (Cloud Watch Events) rule to send events when the upload to the S3 bucket is complete. configure an Amazon Simple Noti cation Service (Amazon SNS) topic as the second rule's target.

D. Create a Docker container to use instead of an EC2 instance. Host the containerized application on Amazon Elastic Container Service (Amazon ECS). configure Amazon CloudWatch Container Insights to send events to an Amazon Simple Noti cation Service (Amazon SNS) topic when the upload to the S3 bucket is complete.
