What should a solutions architect recommend?
Create an Amazon S3 bucket and call the service APIs from each instance’s application
Create an Amazon S3 bucket and configure all instances to access it as a mounted volume
Configure an Amazon Elastic Block Store (Amazon EBS) volume and mount it across all instances
Configure an Amazon Elastic File System (Amazon EFS) file system and mount it across all instances
Explanations:
While using Amazon S3 allows for data sharing, it is not a high-performing solution for low-latency access as S3 is object storage and not designed for real-time file system operations. Additionally, S3 requires API calls, which can introduce overhead.
Similar to option A, configuring an S3 bucket as a mounted volume is not supported natively and would also not provide the necessary performance for real-time applications. It adds latency due to the nature of object storage.
Amazon EBS volumes can only be attached to a single EC2 instance at a time (with the exception of certain multi-attach configurations), making it unsuitable for sharing data across multiple instances concurrently.
Amazon EFS is a managed file system that can be mounted across multiple EC2 instances simultaneously, providing low-latency, high-throughput access to shared data, making it an ideal choice for the company’s needs.
