Amazon Elastic File System (EFS)

Amazon Elastic File System (Amazon EFS) is a fully-managed service offered by Amazon Web Services (AWS) that provides scalable file storage for use with Amazon Elastic Compute Cloud (Amazon EC2) instances. EFS is designed to be used as a file system in the cloud, allowing you to store and access files across multiple EC2 instances.

One of the main benefits of EFS is its ability to scale automatically. As your storage needs change, EFS can automatically increase or decrease the amount of storage capacity available to your applications, without the need for manual intervention. This makes it easy to store and access large amounts of data without worrying about running out of space or experiencing performance issues.

Another key feature of EFS is its high availability. EFS is designed to be highly available, with multiple copies of your data stored across multiple Availability Zones (AZs) within an AWS region. This ensures that your data is always available and can be accessed from any EC2 instance in the region, even if an AZ goes offline.

EFS is also easy to use and integrate into your existing applications. It is compatible with the Network File System (NFS) protocol, which is widely used for file storage in Linux environments. This means that you can easily mount an EFS file system on an EC2 instance and access it using standard Linux file system commands.
