arpio-config:availability-zone

Direct a resource to be recovered into a specific availability zone in your recovery region.

arpio-config:availability-zone[@<rec-account>/<rec-region>] = <rec-az-id>

<rec-account>

An optional part of the tag name that causes Arpio to use this configuration tag only when the resource is being recovered in the specified recovery account and region.

If you specify a recovery account in the tag name, you must also specify a recovery region.

<rec-region>

An optional part of the tag name that causes Arpio to use this configuration tag only when the resource is being recovered in the specified recovery account and region.

If you specify a recovery region in the tag name, you must also specify a recovery account.

<rec-az-id>

The ID of the availability zone where the resource will be placed in the recovery region.

The value must be an availability zone ID. Availability zone IDs are short strings that uniquely identify an availability zone. These IDs look like:

use1-az1
usw2-az2
euw2-az3
sae1-az3

Supported Resources

  • VPC Subnet
  • EC2 EBS Volume

Description

You can use the arpio-config:availability-zone configuration tag to cause some resources to be recovered into a specific availability zone in your recovery region.

Normally, Arpio determines the availability zone to use for a resource automatically, by examining resource availability in the recovery region, and the configuration of your protected resources. If you want to control the placement of your resources for latency, compute affinity, network management, or other reasons, you can use this configuration tag to do so.

You can use this tag on one or more of your resources.   When you set this tag, you can format the tag name to include a specific recovery account and region, or leave those parts out of the name so the renumbering happens in all recovery environments. If you don't specify the recovery account and region part of the tag name, and specify an availability zone ID as the value that does not in your configured recovery region, you'll get an error when Arpio tries to protect your application.

Arpio uses the most specific tag when recovering resources. If there's a tag for a resource that specifies a recovery account and region in the tag name, that tag's value will be used for that recovery environment if there's another tag present that doesn't specify an account and region. The other tag will be used for other recovery environments that don't have a more specific tag.
