Elastic Block Storage (EBS)
  • Amazon Elastic Block Store (Amazon EBS) provides block level storage volumes for use with EC2 instances.
  • EBS volumes behave like raw, unformatted block devices.
  • You can mount these volumes as devices on your instances.
  • EBS volumes that are attached to an instance are exposed as storage volumes that persist independently from the life of the instance.
  • You can create a file system on top of these volumes, or use them in any way you would use a block device (such as a hard drive).
  • AWS recommend Amazon EBS for data that must be quickly accessible and requires long-term persistence.
  • EBS volumes are particularly well-suited for use as the primary storage for file systems, databases, or for any applications that require fine granular updates and access to raw, unformatted, block-level storage.
  • To make a volume available outside of the Availability Zone, you can create a snapshot and restore that snapshot to a new volume anywhere in that Region.
  • EBS Volumes - Availability Zone
    • Amazon EBS volume is tied to its Availability Zone.
    • It can only be attached to instances in the same Availability Zone.
    ​
  • EBS Snapshot - Regional
    • An EBS snapshot is tied to its region.
    • It can only be used to create volumes in the same region and has to be copied from one region to another if needed.

Pricing
