AWS Certified Solutions Architect Associate SAA-C03 Practice Question
An e-commerce company needs a file storage solution accessible by multiple Amazon EC2 instances for processing transaction logs and analytics data in real time. The company expects the data volume to grow unpredictably and wants to avoid manual adjustments to storage capacity while minimizing costs. Which storage solution should the company implement to meet these requirements?
Implement Amazon Elastic File System (Amazon EFS) with storage auto scaling enabled.
Deploy AWS Storage Gateway appliances in EC2 machines.
Use Amazon Elastic Block Store (Amazon EBS) volumes and manually increase capacity as needed.
Utilize instance store volumes and manage storage capacity manually.
Using Amazon Elastic File System (Amazon EFS) with storage auto scaling enabled allows the file system to automatically adjust its capacity as data grows or shrinks. This provides seamless scalability without manual intervention and is cost-effective since the company only pays for the storage used. Manually increasing Amazon Elastic Block Store (Amazon EBS) volumes requires ongoing management and does not support concurrent access from multiple EC2 instances as effectively as Amazon EFS. AWS Storage Gateway is intended for hybrid storage scenarios where on-premises applications can seamlessly use Cloud storage. While it is possible to deploy Storage Gateway appliance in EC2 instances, building a shared file system on top of Amazon storage, this architecture is complex and way costly and have no additional benefits as compared to using Amazon EFS for the same use case. Instance store volumes are ephemeral and not suitable for persistent storage needs.
