SpotFleetAllowedInstanceTypes
Comma-separated list of allowed instance types in the Spot Fleet. This parameter cannot be used together with SpotFleetExcludedInstanceTypes -- if both are set, SpotFleetAllowedInstanceTypes takes precedence. This parameter can be used only when Spot Fleet is enabled by setting SpotFleetMaxPrice.
| Default value | "" |
Wildcard patterns are supported. Examples: m5.8xlarge, c5*.*, m5a.*, r*, *3*.
Use Cases
- Restricting the Spot Fleet to specific instance families (e.g.,
m5.*,c5.*) that are known to work well with your workloads - Limiting to instances with specific hardware capabilities such as enhanced networking or NVMe storage
- Targeting only current-generation instance types to ensure consistent performance
Additional Information
When this parameter is blank (the default), the Spot Fleet considers all instance types that meet the minimum resource requirements defined by SpotFleetMinMemoryMiB and SpotFleetMinVcpuCount.
If you need to exclude specific instance types rather than defining an allow list, use SpotFleetExcludedInstanceTypes instead. The two parameters are mutually exclusive.
This parameter only takes effect when Spot Fleet is enabled via SpotFleetMaxPrice.
