Amazon EFS different than Amazon S3

Amazon EFS provides shared access to data using a traditional file sharing permissions model and hierarchical directory structure via the NFSv4 protocol. Applications that access data using a standard file system interface provided through the operating system can use Amazon EFS to take advantage of the scalability and reliability of file storage in the cloud without writing any new code or adjusting applications.

Amazon S3 is an object storage platform that uses a simple API for storing and accessing data. Applications that do not require a file system structure and are designed to work with object storage can use Amazon S3 as a massively scalable, durable, low-cost object storage solution.
