Fleet quotas - Amazon Elastic Compute Cloud

Fleet quotas

The usual Amazon EC2 quotas (formerly referred to as limits) apply to instances launched by an EC2 Fleet or a Spot Fleet, such as Spot Instance limits and volume limits.

In addition, the following quotas apply:

Quota description Quota
The number of EC2 Fleets and Spot Fleets per Region in the active, deleted_running, and cancelled_running states 1,000 ¹ ² ³ ⁴
The number of Spot capacity pools (unique combination of instance type and subnet) 300 ¹ ⁴
The size of the user data in a launch specification 16 KB ²
The target capacity per EC2 Fleet or Spot Fleet 10,000
The target capacity across all EC2 Fleets and Spot Fleets in a Region 100,000 ¹

An EC2 Fleet request or a Spot Fleet request can't span Regions.

An EC2 Fleet request or a Spot Fleet request can't span different subnets from the same Availability Zone.

¹ These quotas apply to both your EC2 Fleets and your Spot Fleets.

² These are hard quotas. You cannot request an increase for these quotas.

³ After you delete an EC2 Fleet or cancel a Spot Fleet request, and if you specified that the fleet should not terminate its Spot Instances when you deleted or canceled the request, the fleet request enters the deleted_running (EC2 Fleet) or cancelled_running (Spot Fleet) state and the instances continue to run until they are interrupted or you terminate them manually. If you terminate the instances, the fleet request enters the deleted_terminating (EC2 Fleet) or cancelled_terminating ( Spot Fleet) state and does not count towards this quota. For more information, see Delete an EC2 Fleet and Cancel a Spot Fleet request.

⁴ This quota only applies to fleets of type request or maintain. This quota does not apply to instant fleets.
