EBS Volumes

Table of Contents


The Elastic Block Store (EBS) provides persistent, high-performance, and high-availability block-level storage which you can attach to a running EC2 instance (in the same availability zone) in the form of volumes. There are two types of volumes you can create: Standard and Provisioned IOPS. A Standard volume is best suited for boot volumes and provides roughly 100 IOPS (Input/Output Per Second) on average. Provisioned IOPS volumes are designed to provide predictable, high performance I/O workloads that range up to 2,000 IOPS and are best suited for database workloads. Each EBS volume can be formatted and mounted as a file system. An EBS Volume can only be attached to a single instance at a time. Attach EBS Volumes to instances at run-time or boot-time. Multiple volumes can be mounted to the same instance. Take EBS Snapshots of a volume at a particular point in time and then create multiple volumes from a snapshot and place them into any zone. You can also see the lineage of a volume/snapshot to see when it was created, as well as any parent/child relationships.

Note: Changes to EBS Volumes, whether they are creations, attachments, detachments or deletions, often requires several minutes to take effect.
