AWS EFS (Elastic File System) is a scalable, fully-managed file storage service provided by Amazon Web Services (AWS). It provides a simple, scalable, and highly available file system for use with Amazon Elastic Compute Cloud (EC2) instances and other resources.
With AWS EFS, you can create a file system and mount it to multiple EC2 instances, providing a shared file storage solution. This allows multiple EC2 instances to access the same data simultaneously, making it useful for applications that require shared access to files and data.
