ALWAYS_ON

Provides users with instant-on access to their apps. You are charged for all running instances in your fleet, even if no users are streaming apps.

ON_DEMAND

Provide users with access to applications after they connect, which takes one to two minutes. You are charged for instance streaming when users are connected and a small hourly fee for instances that are not streaming apps.

type ComputeCapacity

dict

param ComputeCapacity

The desired capacity for the fleet. This is not allowed for Elastic fleets. For Elastic fleets, specify MaxConcurrentSessions instead.

• DesiredInstances (integer) --

  The desired number of streaming instances.

• DesiredSessions (integer) --

  The desired number of user sessions for a multi-session fleet. This is not allowed for single-session fleets.

  When you create a fleet, you must set either the DesiredSessions or DesiredInstances attribute, based on the type of fleet you create. You can’t define both attributes or leave both attributes blank.

type VpcConfig

dict

param VpcConfig

The VPC configuration for the fleet. This is required for Elastic fleets, but not required for other fleet types. Elastic fleets require that you specify at least two subnets in different availability zones.

• SubnetIds (list) --

  The identifiers of the subnets to which a network interface is attached from the fleet instance or image builder instance. Fleet instances use one or more subnets. Image builder instances use one subnet.

  • (string) --

• SecurityGroupIds (list) --

  The identifiers of the security groups for the fleet or image builder.

  • (string) --

type MaxUserDurationInSeconds

integer

param MaxUserDurationInSeconds

The maximum amount of time that a streaming session can remain active, in seconds. If users are still connected to a streaming instance five minutes before this limit is reached, they are prompted to save any open documents before being disconnected. After this time elapses, the instance is terminated and replaced by a new instance.

Specify a value between 600 and 432000.

type DisconnectTimeoutInSeconds

integer

param DisconnectTimeoutInSeconds

The amount of time that a streaming session remains active after users disconnect. If users try to reconnect to the streaming session after a disconnection or network interruption within this time interval, they are connected to their previous session. Otherwise, they are connected to a new session with a new streaming instance.

Specify a value between 60 and 360000.

type Description

string

param Description

The description to display.

type DisplayName

string

param DisplayName

The fleet name to display.

type EnableDefaultInternetAccess

boolean

param EnableDefaultInternetAccess

Enables or disables default internet access for the fleet.

type DomainJoinInfo

dict

param DomainJoinInfo

The name of the directory and organizational unit (OU) to use to join the fleet to a Microsoft Active Directory domain. This is not allowed for Elastic fleets.

• DirectoryName (string) --

  The fully qualified name of the directory (for example, corp.example.com).

• OrganizationalUnitDistinguishedName (string) --

  The distinguished name of the organizational unit for computer accounts.

type Tags

dict

param Tags

The tags to associate with the fleet. A tag is a key-value pair, and the value is optional. For example, Environment=Test. If you do not specify a value, Environment=.

If you do not specify a value, the value is set to an empty string.

Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following special characters:

_ . : / = + - @

• (string) --

  • (string) --

type IdleDisconnectTimeoutInSeconds

integer

param IdleDisconnectTimeoutInSeconds

The amount of time that users can be idle (inactive) before they are disconnected from their streaming session and the DisconnectTimeoutInSeconds time interval begins. Users are notified before they are disconnected due to inactivity. If they try to reconnect to the streaming session before the time interval specified in DisconnectTimeoutInSeconds elapses, they are connected to their previous session. Users are considered idle when they stop providing keyboard or mouse input during their streaming session. File uploads and downloads, audio in, audio out, and pixels changing do not qualify as user activity. If users continue to be idle after the time interval in IdleDisconnectTimeoutInSeconds elapses, they are disconnected.

To prevent users from being disconnected due to inactivity, specify a value of 0. Otherwise, specify a value between 60 and 3600. The default value is 0.

Note

If you enable this feature, we recommend that you specify a value that corresponds exactly to a whole number of minutes (for example, 60, 120, and 180). If you don't do this, the value is rounded to the nearest minute. For example, if you specify a value of 70, users are disconnected after 1 minute of inactivity. If you specify a value that is at the midpoint between two different minutes, the value is rounded up. For example, if you specify a value of 90, users are disconnected after 2 minutes of inactivity.

type IamRoleArn

string

param IamRoleArn

The Amazon Resource Name (ARN) of the IAM role to apply to the fleet. To assume a role, a fleet instance calls the AWS Security Token Service (STS) AssumeRole API operation and passes the ARN of the role to use. The operation creates a new session with temporary credentials. AppStream 2.0 retrieves the temporary credentials and creates the appstream_machine_role credential profile on the instance.

For more information, see Using an IAM Role to Grant Permissions to Applications and Scripts Running on AppStream 2.0 Streaming Instances in the Amazon AppStream 2.0 Administration Guide .

type StreamView

string

param StreamView

The AppStream 2.0 view that is displayed to your users when they stream from the fleet. When APP is specified, only the windows of applications opened by users display. When DESKTOP is specified, the standard desktop that is provided by the operating system displays.

The default value is APP .

type Platform

string

param Platform

The fleet platform. WINDOWS_SERVER_2019 and AMAZON_LINUX2 are supported for Elastic fleets.

type MaxConcurrentSessions

integer

param MaxConcurrentSessions

The maximum concurrent sessions of the Elastic fleet. This is required for Elastic fleets, and not allowed for other fleet types.

type UsbDeviceFilterStrings

list

param UsbDeviceFilterStrings

The USB device filter strings that specify which USB devices a user can redirect to the fleet streaming session, when using the Windows native client. This is allowed but not required for Elastic fleets.

• (string) --

type SessionScriptS3Location

dict

param SessionScriptS3Location

The S3 location of the session scripts configuration zip file. This only applies to Elastic fleets.

• S3Bucket (string) -- [REQUIRED]

  The S3 bucket of the S3 object.

• S3Key (string) --

  The S3 key of the S3 object.

  This is required when used for the following:

  • IconS3Location (Actions: CreateApplication and UpdateApplication)

  • SessionScriptS3Location (Actions: CreateFleet and UpdateFleet)

  • ScriptDetails (Actions: CreateAppBlock)

  • SourceS3Location when creating an app block with CUSTOM PackagingType (Actions: CreateAppBlock)

      • IdleDisconnectTimeoutInSeconds (integer) --

        The amount of time that users can be idle (inactive) before they are disconnected from their streaming session and the DisconnectTimeoutInSeconds time interval begins. Users are notified before they are disconnected due to inactivity. If users try to reconnect to the streaming session before the time interval specified in DisconnectTimeoutInSeconds elapses, they are connected to their previous session. Users are considered idle when they stop providing keyboard or mouse input during their streaming session. File uploads and downloads, audio in, audio out, and pixels changing do not qualify as user activity. If users continue to be idle after the time interval in IdleDisconnectTimeoutInSeconds elapses, they are disconnected.

        To prevent users from being disconnected due to inactivity, specify a value of 0. Otherwise, specify a value between 60 and 3600. The default value is 0.

        Note

        If you enable this feature, we recommend that you specify a value that corresponds exactly to a whole number of minutes (for example, 60, 120, and 180). If you don't do this, the value is rounded to the nearest minute. For example, if you specify a value of 70, users are disconnected after 1 minute of inactivity. If you specify a value that is at the midpoint between two different minutes, the value is rounded up. For example, if you specify a value of 90, users are disconnected after 2 minutes of inactivity.

      • IamRoleArn (string) --

        The ARN of the IAM role that is applied to the fleet. To assume a role, the fleet instance calls the AWS Security Token Service (STS) AssumeRole API operation and passes the ARN of the role to use. The operation creates a new session with temporary credentials. AppStream 2.0 retrieves the temporary credentials and creates the appstream_machine_role credential profile on the instance.

        For more information, see Using an IAM Role to Grant Permissions to Applications and Scripts Running on AppStream 2.0 Streaming Instances in the Amazon AppStream 2.0 Administration Guide .

      • StreamView (string) --

        The AppStream 2.0 view that is displayed to your users when they stream from the fleet. When APP is specified, only the windows of applications opened by users display. When DESKTOP is specified, the standard desktop that is provided by the operating system displays.

        The default value is APP .

      • Platform (string) --

        The platform of the fleet.

      • MaxConcurrentSessions (integer) --

        The maximum number of concurrent sessions for the fleet.

      • UsbDeviceFilterStrings (list) --

        The USB device filter strings associated with the fleet.

        • (string) --

After this time elapses, the instance is terminated and replaced by a new instance.

Specify a value between 600 and 432000.

type DisconnectTimeoutInSeconds

integer

param DisconnectTimeoutInSeconds

The amount of time that a streaming session remains active after users disconnect. If users try to reconnect to the streaming session after a disconnection or network interruption within this time interval, they are connected to their previous session. Otherwise, they are connected to a new session with a new streaming instance.

Specify a value between 60 and 360000.

type DeleteVpcConfig

boolean

param DeleteVpcConfig

Deletes the VPC association for the specified fleet.

type Description

string

param Description

The description to display.

type DisplayName

string

param DisplayName

The fleet name to display.

type EnableDefaultInternetAccess

boolean

param EnableDefaultInternetAccess

Enables or disables default internet access for the fleet.

type DomainJoinInfo

dict

param DomainJoinInfo

The name of the directory and organizational unit (OU) to use to join the fleet to a Microsoft Active Directory domain.

• DirectoryName (string) --

  The fully qualified name of the directory (for example, corp.example.com).

• OrganizationalUnitDistinguishedName (string) --

  The distinguished name of the organizational unit for computer accounts.

type IdleDisconnectTimeoutInSeconds

integer

param IdleDisconnectTimeoutInSeconds

The amount of time that users can be idle (inactive) before they are disconnected from their streaming session and the DisconnectTimeoutInSeconds time interval begins. Users are notified before they are disconnected due to inactivity. If users try to reconnect to the streaming session before the time interval specified in DisconnectTimeoutInSeconds elapses, they are connected to their previous session. Users are considered idle when they stop providing keyboard or mouse input during their streaming session. File uploads and downloads, audio in, audio out, and pixels changing do not qualify as user activity. If users continue to be idle after the time interval in IdleDisconnectTimeoutInSeconds elapses, they are disconnected.

To prevent users from being disconnected due to inactivity, specify a value of 0. Otherwise, specify a value between 60 and 3600. The default value is 0.

Note

If you enable this feature, we recommend that you specify a value that corresponds exactly to a whole number of minutes (for example, 60, 120, and 180). If you don't do this, the value is rounded to the nearest minute. For example, if you specify a value of 70, users are disconnected after 1 minute of inactivity. If you specify a value that is at the midpoint between two different minutes, the value is rounded up. For example, if you specify a value of 90, users are disconnected after 2 minutes of inactivity.
