Supported Availability Zones for Amazon WorkSpaces Secure Browser
When you are creating a virtual private cloud (VPC) for use with WorkSpaces Secure Browser, your VPC's subnets must reside in different Availability Zones in the Region where you're launching WorkSpaces Secure Browser. Availability Zones are distinct locations that are engineered to be isolated from failures in other Availability Zones. By launching instances in separate Availability Zones, you can protect your applications from the failure of a single location. Each subnet must reside entirely within one Availability Zone and cannot span zones. We recommend configuring a subnet for each supported AZ in your desired region for maximum resiliency
An Availability Zone is represented by a Region code followed by a letter identifier;
for example, us-east-1a. To ensure that resources are distributed across the
Availability Zones for a Region, we independently map Availability Zones to names for each
AWS account. For example, the Availability Zone us-east-1a for your AWS
account might not be the same location as us-east-1a for another AWS
account.
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-az2 is an AZ ID for the us-east-1 Region and it has
the same location in every AWS account.
Viewing AZ IDs enables you to determine the location of resources in one account
relative to the resources in another account. For example, if you share a subnet in the
Availability Zone with the AZ ID use1-az2 with another account, this subnet is
available to that account in the Availability Zone whose AZ ID is also
use1-az2. The AZ ID for each VPC and subnet is displayed in the Amazon VPC
console.
WorkSpaces Secure Browser is available in a subset of the Availability Zones for each supported Region. The following table lists the AZ IDs that you can use for each Region. To see the mapping of AZ IDs to Availability Zones in your account, see AZ IDs for Your Resources in the AWS RAM User Guide.
