class ARCZonalShift.Client

A low-level client representing AWS ARC - Zonal Shift

This is the API Reference Guide for the zonal shift feature of Amazon Route 53 Application Recovery Controller. This guide is for developers who need detailed information about zonal shift API actions, data types, and errors.

Zonal shift is in preview release for Amazon Route 53 Application Recovery Controller and is subject to change.

Zonal shift in Route 53 ARC enables you to move traffic for a load balancer resource away from an Availability Zone. Starting a zonal shift helps your application recover immediately, for example, from a developer's bad code deployment or from an AWS infrastructure failure in a single Availability Zone, reducing the impact and time lost from an issue in one zone.

Supported AWS resources are automatically registered with Route 53 ARC. Resources that are registered for zonal shifts in Route 53 ARC are managed resources in Route 53 ARC. You can start a zonal shift for any managed resource in your account in a Region. At this time, you can only start a zonal shift for Network Load Balancers and Application Load Balancers with cross-zone load balancing turned off.

Zonal shifts are temporary. You must specify an expiration when you start a zonal shift, of up to three days initially. If you want to still keep traffic away from an Availability Zone, you can update the zonal shift and set a new expiration. You can also cancel a zonal shift, before it expires, for example, if you're ready to restore traffic to the Availability Zone.

For more information about using zonal shift, see the Amazon Route 53 Application Recovery Controller Developer Guide.

import boto3

client = boto3.client('arc-zonal-shift')

These are the available methods:

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
cancel_zonal_shift(**kwargs)

Cancel a zonal shift in Amazon Route 53 Application Recovery Controller that you've started for a resource in your AWS account in an AWS Region.

Request Syntax

response = client.cancel_zonal_shift(
    zonalShiftId='string'
)
Parameters
zonalShiftId (string) --

[REQUIRED]

The internally-generated identifier of a zonal shift.

}

Response Structure

  • (dict) --
    • awayFrom (string) --

      The Availability Zone that traffic is moved away from for a resource when you start a zonal shift. Until the zonal shift expires or you cancel it, traffic for the resource is instead moved to other Availability Zones in the AWS Region.

    • comment (string) --

      A comment that you enter about the zonal shift. Only the latest comment is retained; no comment history is maintained. A new comment overwrites any existing comment string.

    • expiryTime (datetime) --

      The expiry time (expiration time) for the zonal shift. A zonal shift is temporary and must be set to expire when you start the zonal shift. You can initially set a zonal shift to expire in a maximum of three days (72 hours). However, you can update a zonal shift to set a new expiration at any time.

      When you start a zonal shift, you specify how long you want it to be active, which Route 53 ARC converts to an expiry time (expiration time). You can cancel a zonal shift, for example, if you're ready to restore traffic to the Availability Zone. Or you can update the zonal shift to specify another length of time to expire in.

    • resourceIdentifier (string) --

      The identifier for the resource to include in a zonal shift. The identifier is the Amazon Resource Name (ARN) for the resource.

      At this time, you can only start a zonal shift for Network Load Balancers and Application Load Balancers with cross-zone load balancing turned off.

    • startTime (datetime) --

      The time (UTC) when the zonal shift is started.

    • status (string) --

      A status for a zonal shift.

      The Status for a zonal shift can have one of the following values:

      • ACTIVE: The zonal shift is started and active.
      • EXPIRED: The zonal shift has expired (the expiry time was exceeded).
      • CANCELED: The zonal shift was canceled.

start_zonal_shift(**kwargs)

You start a zonal shift to temporarily move load balancer traffic away from an Availability Zone in a AWS Region, to help your application recover immediately, for example, from a developer's bad code deployment or from an AWS infrastructure failure in a single Availability Zone. You can start a zonal shift in Route 53 ARC only for managed resources in your account in an AWS Region. Resources are automatically registered with Route 53 ARC by AWS services.

At this time, you can only start a zonal shift for Network Load Balancers and Application Load Balancers with cross-zone load balancing turned off.

When you start a zonal shift, traffic for the resource is no longer routed to the Availability Zone. The zonal shift is created immediately in Route 53 ARC. However, it can take a short time, typically up to a few minutes, for existing, in-progress connections in the Availability Zone to complete.

For more information, see Zonal shift in the Amazon Route 53 Application Recovery Controller Developer Guide.

    PaginationConfig={
        'MaxItems': 123,
        'PageSize': 123,
        'StartingToken': 'string'
    }
)
Parameters
PaginationConfig (dict) --

A dictionary that provides parameters to control pagination.

  • MaxItems (integer) --

Response Structure

  • (dict) --
    • items (list) --

      The items in the response list.

      • (dict) --

        A complex structure for a managed resource in an account.

        A managed resource is a Network Load Balancer or Application Load Balancer that has been registered with Route 53 ARC by Elastic Load Balancing. You can start a zonal shift in Route 53 ARC for a managed resource to temporarily move traffic for the resource away from an Availability Zone in an AWS Region.

        Note

        At this time, you can only start a zonal shift for Network Load Balancers and Application Load Balancers with cross-zone load balancing turned off.

        • arn (string) --

          The Amazon Resource Name (ARN) for the managed resource.

        • availabilityZones (list) --

          The Availability Zones that a resource is deployed in.

          • (string) --
        • name (string) --

          The name of the managed resource.

    • NextToken (string) --

      A token to resume pagination.

class ARCZonalShift.Paginator.ListZonalShifts
paginator = client.get_paginator('list_zonal_shifts')
paginate(**kwargs)

Creates an iterator that will paginate through responses from ARCZonalShift.Client.list_zonal_shifts().

Request Syntax

response_iterator = paginator.paginate(
    status='ACTIVE'|'EXPIRED'|'CANCELED',
    PaginationConfig={
        'MaxItems': 123,

        'StartingToken': 'string'
    }
)
Parameters
  • status (string) --

    A status for a zonal shift.

    The Status for a zonal shift can have one of the following values:

    • ACTIVE : The zonal shift is started and active.
    • EXPIRED : The zonal shift has expired (the expiry time was exceeded).
    • CANCELED : The zonal shift was canceled.
  • PaginationConfig (dict) --

    A dictionary that provides parameters to control pagination.

    • MaxItems (integer) --

      The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.

    • PageSize (integer) --

      The size of each page.

    • StartingToken (string) --

Response Structure

  • (dict) --

    • items (list) --

      The items in the response list.

      • (dict) --

        You start a zonal shift to temporarily move load balancer traffic away from an Availability Zone in a AWS Region. A zonal shift helps your application recover immediately, for example, from a developer's bad code deployment or from an AWS infrastructure failure in a single Availability Zone. You can start a zonal shift in Route 53 ARC only for managed resources in your account in an AWS Region. Supported AWS resources are automatically registered with Route 53 ARC.

        Zonal shifts are temporary. A zonal shift can be active for up to three days (72 hours).

        When you start a zonal shift, you specify how long you want it to be active, which Amazon Route 53 Application Recovery Controller converts to an expiry time (expiration time). You can cancel a zonal shift, for example, if you're ready to restore traffic to the Availability Zone. Or you can extend the zonal shift by updating the expiration so the zonal shift is active longer.

        • awayFrom (string) --

          The Availability Zone that traffic is moved away from for a resource when you start a zonal shift. Until the zonal shift expires or you cancel it, traffic for the resource is instead moved to other Availability Zones in the AWS Region.

        • comment (string) --

          A comment that you enter about the zonal shift. Only the latest comment is retained; no comment history is maintained. That is, a new comment overwrites any existing comment string.

        • expiryTime (datetime) --

          The expiry time (expiration time) for the zonal shift. A zonal shift is temporary and must be set to expire when you start the zonal shift. You can initially set a zonal shift to expire in a maximum of three days (72 hours). However, you can update a zonal shift to set a new expiration at any time.

          When you start a zonal shift, you specify how long you want it to be active, which Route 53 ARC converts to an expiry time (expiration time). You can cancel a zonal shift, for example, if you're ready to restore traffic to the Availability Zone. Or you can update the zonal shift to specify another length of time to expire in.

        • resourceIdentifier (string) --

          The identifier for the resource to include in a zonal shift. The identifier is the Amazon Resource Name (ARN) for the resource.

          At this time, you can only start a zonal shift for Network Load Balancers and Application Load Balancers with cross-zone load balancing turned off.

        • startTime (datetime) --

          The time (UTC) when the zonal shift is started.

        • status (string) --

          A status for a zonal shift.

          The Status for a zonal shift can have one of the following values:

          • ACTIVE: The zonal shift is started and active.
          • EXPIRED: The zonal shift has expired (the expiry time was exceeded).
          • CANCELED: The zonal shift was canceled.
        • zonalShiftId (string) --

          The identifier of a zonal shift.

    • NextToken (string) --

      A token to resume pagination.
