Multi-Attach is now available on Amazon EBS Provisioned IOPS volume type, io2. Launched in August 2020, io2 is the newest generation of our Provisioned IOPS volume type designed for 99.999% durability (100x io1) and 500:1 IOPS:GiB (10x io1). Multi-Attach lets you share access to an EBS data volume between up to 16 Nitro-based EC2 instances within the same Availability Zone (AZ). Each attached instance has full read and write permission to the shared volume. Multi-Attach is intended to make it easier to achieve higher application availability for customers that want to deploy applications that manage storage consistency from multiple writers in shared storage infrastructure.
