Which AWS service allows for file sharing between multiple Amazon EC2 instances?
AWS Direct Connect
AWS Snowball Edge
AWS Backup
Amazon Elastic File System (Amazon EFS)
Explanations:
AWS Direct Connect is a service for establishing a dedicated network connection to AWS, not for file sharing.
AWS Snowball Edge is a data transfer service used for moving large amounts of data into and out of AWS, not for file sharing.
AWS Backup is a service for centralized backup management, not specifically for file sharing between EC2 instances.
Amazon Elastic File System (Amazon EFS) provides a scalable file storage solution that can be mounted by multiple EC2 instances, enabling file sharing.
I appraise that the answer is:
Amazon Elastic File System (Amazon EFS)
