Quotas for EC2 Fleet and Spot Fleet
Your AWS account has default quotas, formerly referred to as limits, for each AWS 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 AWS 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.
