Amazon Elastic File System (EFS) is a scalable managed file storage service provided by Amazon Web Services (AWS). It offers an elastic and fully managed file system that can be accessed concurrently from multiple Amazon EC2 instances or on-premises servers via the Network File System (NFS) protocol.
EFS offers a simple and scalable solution for storing and accessing files from multiple instances concurrently, making it an ideal choice for applications that require shared file storage. It eliminates the need for managing infrastructure or capacity planning, allowing you to focus on your application development.
Amazon EFS is well-suited for a variety of use cases, including:
To start using EFS, you need to create a file system and associate it with one or more Amazon EC2 instances or on-premises servers. You can do this using the AWS Management Console, AWS Command Line Interface (CLI), or AWS SDKs. Once the file system is created, you can mount it on your instances just like a regular file system and start using it to store and access files.
It's important to note that you are charged based on the amount of data stored in EFS, as well as the number of file system requests you make. You can refer to the AWS Pricing page for detailed pricing information.
Summary: Amazon Elastic File System (EFS) is a scalable managed file storage service provided by AWS. It offers an elastic and fully managed file system for storing and accessing files from multiple instances concurrently. With its scalability, elasticity, high availability, and security features, EFS is well-suited for various use cases such as content management systems, big data analytics, web serving, and development/testing environments.
