A company is planning to migrate its on-premises transaction-processing application to AWS. The application runs inside Docker containers that are hosted on VMs in the company's data center. The…

Amazon Elastic Kubernetes Service (EKS) provides container orchestration but requires more management overhead than Fargate for simpler deployments, and it doesn't inherently solve the shared storage scaling issue, though it can integrate with EFS.

AWS Fargate for Amazon ECS allows running Docker containers without managing the underlying EC2 instances, meeting the 'cannot administer Docker hosting environment' requirement. Amazon EFS provides a scalable, low-latency, shared file system that automatically scales throughput and capacity, which is suitable for the transactional application's shared storage needs and meets the 'cannot develop the application further' constraint by providing a familiar file interface.

Using Amazon S3 for shared storage is inappropriate for a transactional application that requires a file system interface with low-latency access to transaction data; S3 is object storage and lacks the file system semantics necessary.

Launching Amazon EC2 instances and installing Docker on them directly contradicts the requirement that the company 'cannot continue to administer the Docker hosting environment' as it places the burden of VM and Docker management on them.
