Quotas for EC2 Fleet and Spot Fleet
Your Amazon Web Services account has default quotas, formerly referred to as limits, for each Amazon service. Unless otherwise noted, each quota is Region-specific.
The usual Amazon EC2 quotas apply to instances launched by an EC2 Fleet or a Spot Fleet, such as Spot Instance limits and volume limits.
In addition, your Amazon Web Services account has the following quotas related to EC2 Fleet and Spot Fleet:
| Quota description | Quota |
|---|---|
The number of EC2 Fleets and Spot Fleets per Region of type
maintain and request in the
active, deleted_running, and
cancelled_running states |
1,000 ¹ ² ³ |
The number of EC2 Fleets of type instant |
Unlimited |
The number of Spot capacity pools (unique combination of instance
type and subnet) for EC2 Fleets and Spot Fleets of type maintain and
request |
300 ¹ |
The number of Spot capacity pools (unique combination of instance
type and subnet) for EC2 Fleets of type instant |
Unlimited |
| 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 can't 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 request and the instances in the
fleet and Cancel (delete) a Spot Fleet request.
