Spot Instance quotas
There are quotas for the number of running Spot Instances and pending Spot Instance requests per AWS account per Region. After a pending Spot Instance request is fulfilled, the request no longer counts towards the quota because the running instance is counted towards the quota.
Spot Instance quotas are managed in terms of the number of virtual central processing units (vCPUs) that your running Spot Instances are either using or will use pending the fulfillment of open Spot Instance requests. If you terminate your Spot Instances but do not cancel the Spot Instance requests, the requests count against your Spot Instance vCPU quota until Amazon EC2 detects the Spot Instance terminations and closes the requests.
We provide the following quota types for Spot Instances.
You can launch any combination of instance types that meet your changing application needs.
For example, with an All Standard Spot Instance Requests quota of 256 vCPUs, you could request 32
m5.2xlarge Spot Instances (32 x 8 vCPUs) or 16 c5.4xlarge Spot Instances (16
x 16
vCPUs).
