  • message - Information about the Availability Zone.
  • region-name - The name of the Region for the Availability Zone (for example, us-east-1).
  • state - The state of the Availability Zone (available | information | impaired | unavailable).

Specifying the name of a property of type Amazon.EC2.Model.DescribeAvailabilityZonesResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AWSProfileName, StoredCredentials
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.

Aliases RegionToCall
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False

Accept pipeline input? True (ByPropertyName)

Inputs

System.String[]
You can pipe a String[] object to this cmdlet for the ZoneName parameter.

Outputs

Amazon.EC2.Model.AvailabilityZone or Amazon.EC2.Model.DescribeAvailabilityZonesResponse
This cmdlet returns a collection of Amazon.EC2.Model.AvailabilityZone objects. The service call response (type Amazon.EC2.Model.DescribeAvailabilityZonesResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

PS C:\> Get-EC2AvailabilityZone

Messages    RegionName    State        ZoneName
--------    ----------    -----        --------
{}          us-west-2     available    us-west-2a
{}          us-west-2     available    us-west-2b
{}          us-west-2     available    us-west-2c
This example describes the Availability Zones for the current region that are available to you.

Example 2

PS C:\>Get-EC2AvailabilityZone -Filter @{ Name="state";Values="impaired" }
This example describes any Availability Zones that are in an impaired state. The syntax used by this example requires PowerShell version 3 or higher.

Example 3

PS C:\> $filter = New-Object Amazon.EC2.Model.Filter
PS C:\> $filter.Name = "state"
PS C:\> $filter.Values = "impaired"

PS C:\>Get-EC2AvailabilityZone -Filter $filter
With PowerShell version 2, you must use New-Object to create the filter.
