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.

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.

* 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.
