Describir las zonas de disponibilidad

En el siguiente ejemplo de describe-availability-zones, se muestran los detalles de las zonas de disponibilidad que están disponibles para usted. La respuesta incluye las zonas de disponibilidad solo para la región actual. En este ejemplo, se usa la región predeterminada del perfil us-west-2 (Oregón).

Ejemplo 1: En este ejemplo se describen las zonas de disponibilidad de la región actual que están disponibles.

Get-EC2AvailabilityZone

Salida:

Messages    RegionName    State        ZoneName

Ejemplo 2: En este ejemplo se describe cualquier zona de disponibilidad que se encuentre en un estado dañado. La sintaxis utilizada en este ejemplo requiere la versión 3 o posterior de PowerShell.

Get-EC2AvailabilityZone -Filter @{ Name="state";Values="impaired" }

Ejemplo 3: Con la versión 2 de PowerShell, debe usar New-Object para crear cada filtro.

$filter = New-Object Amazon.EC2.Model.Filter
$filter.Name = "state"
$filter.Values = "impaired"
