Start a zonal shift for your Network Load Balancer

The steps in this procedure explain how to start a zonal shift using the Amazon EC2 console. For steps to start a zonal shift using the ARC console, see Starting a zonal shift in the Amazon Application Recovery Controller (ARC) Developer Guide.

Prerequisite

Before you begin, verify that you enabled zonal shift for the load balancer.

To start a zonal shift using the console

  1. Open the Amazon EC2 console at https://console.amazonaws.cn/ec2/.

  2. On the navigation pane, under Load Balancing, choose Load Balancers.

  3. Select the Network Load Balancer.

  4. On the Integrations tab, under Amazon Application Recovery Controller (ARC), choose Start zonal shift.

  5. Select the Availability Zone that you want to move traffic away from.

  6. Choose or enter an expiration for the zonal shift. A zonal shift can initially be set from 1 minute up to three days (72 hours).

    All zonal shifts are temporary. You must set an expiration, but you can update active shifts later to set a new expiration.

  7. Enter a comment. You can update the zonal shift later to edit the comment, if you like.

  8. Select the check box to acknowledge that starting a zonal shift reduces capacity for your application by shifting traffic away from the Availability Zone.

  9. Choose Confirm.
