The amount of time that a streaming session remains active after users disconnect.

notes

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 36000.

fleetTypeoptionalstringfleet_typeoptionalstrfleetTypeoptionalStringFleetTypeoptionalstringFleetTypeoptional*string#

The fleet type.

notes

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.
ELASTIC - The pool of streaming instances is managed by Amazon AppStream 2.0. When a user selects their application or desktop to launch, they will start streaming after the app block has been downloaded and mounted to a streaming instance.

Allowed Values : ALWAYS_ON | ELASTIC | ON_DEMAND

iamRoleArnoptionalstringiam_role_arnoptionalstriamRoleArnoptionalStringIamRoleArnoptionalstringIamRoleArnoptional*string#

The ARN of the IAM role that is applied to the fleet.

notes

To assume a role, the fleet instance calls the Security Token Service 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 .

idleDisconnectTimeoutInSecondsoptionalnumberidle_disconnect_timeout_in_secondsoptionalint | floatidleDisconnectTimeoutInSecondsoptionalNumberIdleDisconnectTimeoutInSecondsoptionaldoubleIdleDisconnectTimeoutInSecondsoptional*float64#

The amount of time that users can be idle (inactive) before they are disconnected from their streaming session and the `DisconnectTimeoutInSeconds` time interval begins.

notes

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 36000.

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.

The ARN of the public, private, or shared image to use.

maxConcurrentSessionsoptionalnumbermax_concurrent_sessionsoptionalint | floatmaxConcurrentSessionsoptionalNumberMaxConcurrentSessionsoptionaldoubleMaxConcurrentSessionsoptional*float64#

The maximum number of concurrent sessions that can be run on an Elastic fleet.

This setting is required for Elastic fleets, but is not used for other fleet types.

maxSessionsPerInstanceoptionalnumbermax_sessions_per_instanceoptionalint | floatmaxSessionsPerInstanceoptionalNumberMaxSessionsPerInstanceoptionaldoubleMaxSessionsPerInstanceoptional*float64#

Max number of user sessions on an instance.

This is applicable only for multi-session fleets.

The maximum amount of time that a streaming session can remain active, in seconds.

notes

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.
