Amazon EFS
Amazon Elastic File System (EFS) is a fully managed, scalable, and serverless network file storage service provided by AWS. It offers shared file storage that can be accessed concurrently by multiple Amazon EC2 instances, containers, and serverless applications, with automatic scaling to petabytes of data. EFS supports the Network File System (NFS) protocol and is designed for high availability and durability across multiple Availability Zones.
Developers should use Amazon EFS when building applications that require shared file storage across multiple compute instances, such as content management systems, web serving, data analytics, or media processing workloads. It is ideal for scenarios where data needs to be accessed and modified by distributed systems, as it provides low-latency performance and integrates seamlessly with AWS services like EC2, ECS, and Lambda. EFS simplifies storage management by eliminating the need for provisioning or managing file servers.
