Question
A company is using a third-party service to back up 10 TB of data to a tape library. The on-premises backup server is running out of space. The company wants to use AWS services for the backups without changing their existing backup workflows. Which AWS service should the company use to meet these requirements?
A. Amazon Elastic Block Store (Amazon EBS)
B. AWS Storage Gateway
C. Amazon Elastic Container Service (Amazon ECS)
D. AWS Lambda
Answer
B. AWS Storage Gateway
Explanation
The company should use AWS Storage Gateway, specifically the Tape Gateway option, to integrate their existing backup workflows with AWS without the need for significant changes, allowing for efficient backup to the cloud.
AWS Storage Gateway is a hybrid cloud storage service that seamlessly integrates on-premises environments with AWS cloud storage. It supports existing workflows by providing interfaces compatible with popular backup software and systems, such as tape libraries or block storage.
Key reasons why AWS Storage Gateway is the right choice in this scenario:
- Tape Gateway Integration: The Tape Gateway mode emulates a physical tape library, allowing companies to replace their physical tapes with virtual tapes stored in Amazon S3 or Amazon S3 Glacier for long-term archival. This ensures compatibility with existing backup software and workflows.
- No Workflow Changes Required: By presenting itself as a local iSCSI interface, Storage Gateway enables businesses to continue using their current backup infrastructure without modification.
- Scalability and Cost Efficiency: Data is stored in the cloud, providing virtually unlimited storage capacity while reducing the need for additional on-premises hardware.
- Centralized Backup Management: Integration with AWS Backup allows for centralized management of backups across both on-premises and cloud environments, simplifying operations and compliance management.
Why Not the Other Options?
A. Amazon Elastic Block Store (Amazon EBS): EBS is designed for block storage attached to EC2 instances and does not support direct integration with on-premises backup systems.
C. Amazon Elastic Container Service (Amazon ECS): ECS is a container orchestration service and unrelated to data backup or storage workflows.
D. AWS Lambda: Lambda is a serverless compute service designed for running code in response to events, not for managing or storing backups.
AWS Storage Gateway is purpose-built to address the need for integrating on-premises backup systems with scalable and cost-efficient AWS cloud storage, making it the optimal choice in this scenario. This knowledge is critical for success in the AWS Certified Cloud Practitioner CLF-C02 exam.
