Which AWS service should the company use to meet these requirements?
Amazon Elastic Block Store (Amazon EBS)
AWS Storage Gateway
Amazon Elastic Container Service (Amazon ECS)
AWS Lambda
Explanations:
Amazon EBS is a block storage service designed for use with Amazon EC2 instances, but it does not provide a backup solution that integrates with on-premises workflows or tape libraries.
AWS Storage Gateway allows on-premises applications to use AWS cloud storage seamlessly. It supports backup and archiving workflows, enabling the company to back up data to Amazon S3 or Amazon S3 Glacier while still utilizing existing backup processes.
Amazon ECS is a container orchestration service that manages Docker containers. It is not suitable for backup purposes or integrating with existing backup workflows that involve tape libraries.
AWS Lambda is a serverless compute service that runs code in response to events but is not intended for storage or backup solutions. It does not align with the requirement to back up large volumes of data from on-premises to AWS.
I design that the answer is:
AWS Storage Gateway
