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.
