A company currently operates an on-premises SaaS solution that daily ingests multiple files from its customers. To facilitate these transfers, the company offers public SFTP endpoints, which customers have added to their firewall allow lists for outbound traffic. The customers strictly prohibit any changes to these SFTP endpoint IP addresses. The company aims to migrate this SaaS solution to AWS while reducing the operational burden associated with file transfer services. What AWS solution aligns with these requirements?
A
Register the customer-owned IP address block within the company's AWS account. Generate Elastic IP addresses from this pool and assign them to an AWS Transfer for SFTP endpoint. Utilize AWS Transfer to store the files in an Amazon S3 bucket.
B
Include a subnet with the customer-owned IP address block in a VPC. Generate Elastic IP addresses from this pool and assign them to an Application Load Balancer (ALB). Deploy EC2 instances hosting FTP services in an Auto Scaling group behind the ALB. Store the files on attached Amazon Elastic Block Store (Amazon EBS) volumes.
C
Register the customer-owned IP address block with Amazon Route 53. Create alias records in Route 53 that direct to a Network Load Balancer (NLB). Launch EC2 instances hosting FTP services in an Auto Scaling group behind the NLB. Store the files in an Amazon S3 bucket.
D
Register the customer-owned IP address block within the company's AWS account. Generate Elastic IP addresses from this pool and assign them to an Amazon S3 VPC endpoint. Enable SFTP support on the S3 bucket.
