Amazon EFS (Elastic File System) is appreciated for scalability, cost-effectiveness, and AWS reliability, ensuring no downtime. It provides secure file storage within VPC but has limited Windows features and performance issues on learning systems. Users find it costly due to data transfer expenses. The setup process requires technical expertise, and lengthy support response times can hinder quick resolutions. Though beneficial, its complexities demand careful consideration for AWS environments.
