Fleet quotas - Amazon Elastic Compute Cloud

Fleet quotas

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, the following limits apply:

  • The number of active EC2 Fleets and Spot Fleets per Region: 1,000* †

  • The number of Spot capacity pools (unique combination of instance type and subnet): 300* ‡

  • The size of the user data in a launch specification: 16 KB †

  • 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*

  • 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.

* These limits apply to both your EC2 Fleets and your Spot Fleets.

† These are hard limits. You cannot request a limit increase for these limits.

‡ This limit only applies to fleets of type request or maintain. This limit does not apply to instant fleets.

To request a limit increase for target capacity

If you need more than the default limits for target capacity, complete the AWS Support Center Create case form to request a limit increase. For Limit type, choose EC2 Fleet, choose a Region, and then choose Target Fleet Capacity per Fleet (in units) or Target Fleet Capacity per Region (in units), or both.
