Amazon EFS
Amazon Elastic File System (EFS) is a fully managed, scalable, and elastic network file storage service provided by AWS. It offers a simple, serverless interface for creating and configuring file systems that can be shared across multiple Amazon EC2 instances, containers, and serverless applications. EFS automatically scales storage capacity up or down as files are added or removed, providing high availability and durability with data stored across multiple Availability Zones.
Developers should use Amazon EFS when building applications that require shared file storage across multiple compute instances, such as web serving environments, content management systems, or data analytics workloads. It is particularly useful for containerized applications using Amazon ECS or EKS, as it provides persistent storage that can be mounted by multiple containers simultaneously. EFS simplifies storage management by eliminating the need to provision and manage file servers, making it ideal for scalable and distributed applications on AWS.
