Because the workload follows apredictable business-hours schedule, the lowest-overhead solution is to usescheduled scalingwith EC2 Auto Scaling. AWS documentation states that scheduled actions let you scale an Auto Scaling group at specific times or on recurring schedules by changing desired, minimum, and maximum capacity. That directly matches a workload that needs instances during business hours and not at night. Manual start and stop actions add operational work, Spot Instances risk interruptions during business hours, and sizing for maximum load with Reserved Instances would overpay for idle time. Scheduled scaling automates the exact time-based pattern the question describes.

AWS Transfer Family is a fully managed service that provides SFTP, FTPS, and FTP access directly to Amazon S3. It allows organizations to support legacy data transfer protocols without managing infrastructure. This approach gives the vendors a familiar SFTP interface, with files landing directly in S3, and requires minimal operational effort compared to managing EC2 servers or using gateways.

Reference Extract from AWS Documentation / Study Guide:

" AWS Transfer Family enables secure transfer of files directly into and out of Amazon S3 using SFTP, FTPS, and FTP, and is fully managed by AWS, significantly reducing operational overhead. "

Detailed Explanation:

A. ECS + API Gateway:Overly complex and costly for an on-demand, intermittent workload.

B. EventBridge + SNS:EventBridge schedules are unnecessary for on-demand generation.

C. EKS + API Gateway:Overkill for this use case, with high operational overhead.

D. Lambda + SES:Most cost-effective and efficient solution for generating and emailing reports on demand.
