Amazon Elastic Block Store (EBS) Multi-Attach allows an EBS volume to be attached to multiple Amazon Elastic Compute Cloud (EC2) instances at the same time. This feature allows you to build highly available and scalable applications by sharing storage across multiple instances. This feature is available for Nitro-based EC2 instances that are running in the same availability zone.

To build highly available storage using EBS multi-attach feature, you need cluster-aware file systems which allow you to read and write the same file systems from multiple instances. Before checking out more on EBS Multi-Attach, we need to understand the term “cluster-aware” and “Nitro-based” EC2 instances.

Cluster-aware file system:

A cluster-aware file system is a type of file system that is specifically designed to work with a cluster of computers, allowing multiple nodes to access and modify the file system simultaneously. These file systems are typically designed to handle issues such as data consistency and availability and to provide transparent failover and recovery in the event of a node failure.
