S3 Express One Zone Availability Zones and Regions
An Availability Zone is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region. To optimize low-latency retrievals, objects in the Amazon S3 Express One Zone storage class are redundantly stored in S3 directory buckets in a single Availability Zone that's local to your compute workload. When you create a directory bucket, you choose the Availability Zone and AWS Region where your bucket will be located.
AWS maps the physical Availability Zones randomly to the Availability Zone names for
each AWS account. This approach helps to distribute resources across the Availability
Zones in an AWS Region, instead of resources likely being concentrated in the first
Availability Zone for each Region. As a result, the Availability Zone
us-east-1a
for your AWS account might not represent the same physical
location as us-east-1a
for a different AWS account. For more information, see
Regions and
Availability Zones in the Amazon EC2 User Guide.
To coordinate Availability Zones across accounts, you must use the AZ ID, which is a unique and consistent identifier for an Availability Zone.
For example, use1-az1
is an AZ ID for the us-east-1
Region and it
has the same physical location in every AWS account. The following illustration shows how
the AZ IDs are the same for every account, even though the Availability Zone names might be
mapped differently for each account.
With
S3 Express One Zone, your data is redundantly stored on multiple devices within a single
Availability Zone. S3 Express One Zone is designed for 99.95 percent availability within a single Availability Zone and is backed
by the Amazon S3 Service Level Agreement
