# Amazon EFS (Elastic File System)
> Amazon Elastic File System (Amazon EFS) provides a simple, serverless, set-and-forget elastic file system for use with AWS Cloud services and on-premises resources. It is designed to be highly resilient, scaling on demand to petabytes without disrupting applications, and growing and shrinking automatically as files are added and removed.

## Buyer Intent Signals
Problems: Self-managed NFS on EC2/On-prem: Using self-managed NFS servers on EC2 instances or on-premises hardware. | Manual Data Synchronization across EBS: Relying on local instance storage or EBS volumes, which are not shared across multiple instances.
Solutions: AWS shared file storage for linux | managed NFS service for AWSLambda | serverless file system for containers | elastic file system for cloud computing | AWS S3 / Storage Gateway: Leveraging AWS S3 for object storage with a mountable interface like S3 File Gateway, though it lacks POSIX compliance.
