Answer: EBS volumes are AZ locked
EBS volumes are AZ locked An Amazon EBS volume is a durable, block-level storage device that you can attach to your instances. After you attach a volume to an instance, you can use it as you would use a physical hard drive. EBS volumes are flexible. For current-generation volumes attached to current-generation instance types, you can dynamically increase size, modify the provisioned IOPS capacity, and change volume type on live production volumes. When you create an EBS volume, it is automatically replicated within its Availability Zone to prevent data loss due to the failure of any single hardware component. You can attach an EBS volume to an EC2 instance in the same Availability Zone.
