This is the new *CloudFormation Template Reference Guide*. Please update your bookmarks and links. For help getting started with CloudFormation, see the [AWS CloudFormation User Guide](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/Welcome.html). # AWS::EC2::SpotFleet Specifies a Spot Fleet request. The Spot Fleet request specifies the total target capacity and the On-Demand target capacity. Amazon EC2 calculates the difference between the total capacity and On-Demand capacity, and launches the difference as Spot capacity. You can submit a single request that includes multiple launch specifications that vary by instance type, AMI, Availability Zone, or subnet. By default, the Spot Fleet requests Spot Instances in the Spot Instance pool where the price per unit is the lowest. Each launch specification can include its own instance weighting that reflects the value of the instance type to your application workload. Alternatively, you can specify that the Spot Fleet distribute the target capacity across the Spot pools included in its launch specifications. By ensuring that the Spot Instances in your Spot Fleet are in different Spot pools, you can improve the availability of your fleet. You can specify tags for the Spot Fleet request and instances launched by the fleet. You cannot tag other resource types in a Spot Fleet request because only the `spot-fleet-request` and `instance` resource types are supported. For more information, see [Spot Fleet](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-fleet.html) in the *Amazon EC2 User Guide*. ## Syntax To declare this entity in your CloudFormation template, use the following syntax: ### JSON ``` { "Type" : "AWS::EC2::SpotFleet", "Properties" : { "[SpotFleetRequestConfigData](#cfn-ec2-spotfleet-spotfleetrequestconfigdata)" : SpotFleetRequestConfigData, "[Tags](#cfn-ec2-spotfleet-tags)" : [ Tag, ... ] } } ``` ### YAML ``` Type: AWS::EC2::SpotFleet Properties: [SpotFleetRequestConfigData](#cfn-ec2-spotfleet-spotfleetrequestconfigdata): SpotFleetRequestConfigData [Tags](#cfn-ec2-spotfleet-tags): - Tag ``` ## Properties `SpotFleetRequestConfigData` Describes the configuration of a Spot Fleet request. *Required*: Yes *Type*: [SpotFleetRequestConfigData](aws-properties-ec2-spotfleet-spotfleetrequestconfigdata.md) *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `Tags` The tags for a Spot Fleet resource. *Required*: No *Type*: Array of [Tag](aws-properties-ec2-spotfleet-tag.md) *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) ## Return values ### Ref When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the ID of the Spot Fleet.

Instance store volumes are numbered starting from 0. An instance type with 2 available instance store volumes can specify mappings for `ephemeral0` and `ephemeral1`. The number of available instance store volumes depends on the instance type. After you connect to the instance, you must mount the volume. NVMe instance store volumes are automatically enumerated and assigned a device name. Including them in your block device mapping has no effect. Constraints: For M3 instances, you must specify instance store volumes in the block device mapping for the instance. When you launch an M3 instance, we ignore any instance store volumes specified in the block device mapping for the AMI. *Required*: Conditional *Type*: String *Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement) # AWS::EC2::SpotFleet ClassicLoadBalancer Specifies a Classic Load Balancer. ## Syntax To declare this entity in your CloudFormation template, use the following syntax: ### JSON ``` { "[Name](#cfn-ec2-spotfleet-classicloadbalancer-name)" : String } ``` ### YAML ``` [Name](#cfn-ec2-spotfleet-classicloadbalancer-name): String ``` ## Properties `Name` The name of the load balancer. *Required*: Yes *Type*: String *Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement) # AWS::EC2::SpotFleet ClassicLoadBalancersConfig Specifies the Classic Load Balancers to attach to a Spot Fleet.

When you specify instance attributes, Amazon EC2 will identify instance types with these attributes. You must specify `VCpuCount` and `MemoryMiB`. All other attributes are optional. Any unspecified optional attribute is set to its default. When you specify multiple attributes, you get instance types that satisfy all of the specified attributes. If you specify multiple values for an attribute, you get instance types that satisfy any of the specified values. To limit the list of instance types from which Amazon EC2 can identify matching instance types, you can use one of the following parameters, but not both in the same request: + `AllowedInstanceTypes` - The instance types to include in the list. All other instance types are ignored, even if they match your specified attributes. + `ExcludedInstanceTypes` - The instance types to exclude from the list, even if they match your specified attributes. **Note** If you specify `InstanceRequirements`, you can't specify `InstanceType`. Attribute-based instance type selection is only supported when using Auto Scaling groups, EC2 Fleet, and Spot Fleet to launch instances.

The identified On-Demand price is the price of the lowest priced current generation C, M, or R instance type with your specified attributes. If no current generation C, M, or R instance type matches your attributes, then the identified price is from the lowest priced current generation instance types, and failing that, from the lowest priced previous generation instance types that match your attributes. When Amazon EC2 selects instance types with your attributes, it will exclude instance types whose price exceeds your specified threshold. The parameter accepts an integer, which Amazon EC2 interprets as a percentage. If you set `TargetCapacityUnitType` to `vcpu` or `memory-mib`, the price protection threshold is based on the per vCPU or per memory price instead of the per instance price. Only one of `SpotMaxPricePercentageOverLowestPrice` or `MaxSpotPriceAsPercentageOfOptimalOnDemandPrice` can be specified. If you don't specify either, Amazon EC2 will automatically apply optimal price protection to consistently select from a wide range of instance types.

The identified On-Demand price is the price of the lowest priced current generation C, M, or R instance type with your specified attributes. When Amazon EC2 selects instance types with your attributes, it will exclude instance types whose price exceeds your specified threshold. The parameter accepts an integer, which Amazon EC2 interprets as a percentage. To indicate no price protection threshold, specify a high value, such as `999999`.

The identified Spot price is the Spot price of the lowest priced current generation C, M, or R instance type with your specified attributes. If no current generation C, M, or R instance type matches your attributes, then the identified Spot price is from the lowest priced current generation instance types, and failing that, from the lowest priced previous generation instance types that match your attributes. When Amazon EC2 selects instance types with your attributes, it will exclude instance types whose Spot price exceeds your specified threshold. The parameter accepts an integer, which Amazon EC2 interprets as a percentage. If you set `TargetCapacityUnitType` to `vcpu` or `memory-mib`, the price protection threshold is applied based on the per-vCPU or per-memory price instead of the per-instance price.

launch template override. The highest priority is launched first. If `OnDemandAllocationStrategy` is set to `prioritized`, Spot Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity. If the Spot `AllocationStrategy` is set to `capacityOptimizedPrioritized`, Spot Fleet uses priority on a best-effort basis to determine which launch template override to use in fulfilling Spot capacity, but optimizes for capacity first. Valid values are whole numbers starting at `0`. The lower the number, the higher the priority. If no number is set, the launch template override has the lowest priority.

These are the same units that you chose to set the target capacity in terms of instances, or a performance characteristic such as vCPUs, memory, or I/O. If the target capacity divided by this value is not a whole number, Amazon EC2 rounds the number of instances to the next whole number. If this value is not specified, the default is 1. When specifying weights, the price used in the `lowestPrice` and `priceCapacityOptimized` allocation strategies is per *unit* hour (where the instance price is divided by the specified weight).

For more information, see [Allocation strategies for Spot Instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-fleet-allocation-strategy.html) in the *Amazon EC2 User Guide*. priceCapacityOptimized (recommended) Spot Fleet identifies the pools with the highest capacity availability for the number of instances that are launching. This means that we will request Spot Instances from the pools that we believe have the lowest chance of interruption in the near term. Spot Fleet then requests Spot Instances from the lowest priced of these pools. capacityOptimized Spot Fleet identifies the pools with the highest capacity availability for the number of instances that are launching. This means that we will request Spot Instances from the pools that we believe have the lowest chance of interruption in the near term. To give certain instance types a higher chance of launching first, use `capacityOptimizedPrioritized`. Set a priority for each instance type by using the `Priority` parameter for `LaunchTemplateOverrides`. You can assign the same priority to different `LaunchTemplateOverrides`. EC2 implements the priorities on a best-effort basis, but optimizes for capacity first. `capacityOptimizedPrioritized` is supported only if your Spot Fleet uses a launch template. Note that if the `OnDemandAllocationStrategy` is set to `prioritized`, the same priority is applied when fulfilling On-Demand capacity. diversified Spot Fleet requests instances from all of the Spot Instance pools that you specify. lowestPrice (not recommended) We don't recommend the `lowestPrice` allocation strategy because it has the highest risk of interruption for your Spot Instances. Spot Fleet requests instances from the lowest priced Spot Instance pool that has available capacity. If the lowest priced pool doesn't have available capacity, the Spot Instances come from the next lowest priced pool that has available capacity. If a pool runs out of capacity before fulfilling your desired capacity, Spot Fleet will continue to fulfill your request by drawing from the next lowest priced pool. To ensure that your desired capacity is met, you might receive Spot Instances from several pools. Because this strategy only considers instance price and not capacity availability, it might lead to high interruption rates.

Valid only when Spot **AllocationStrategy** is set to `lowest-price`. Spot Fleet selects the cheapest Spot pools and evenly allocates your target Spot capacity across the number of Spot pools that you specify. Note that Spot Fleet attempts to draw Spot Instances from the number of pools that you specify on a best effort basis. If a pool runs out of Spot capacity before fulfilling your target capacity, Spot Fleet will continue to fulfill your request by drawing from the next cheapest pool. To ensure that your target capacity is met, you might receive Spot Instances from more than the number of pools that you specified.

If you specify `lowestPrice`, Spot Fleet uses price to determine the order, launching the lowest price first. If you specify `prioritized`, Spot Fleet uses the priority that you assign to each Spot Fleet launch template override, launching the highest priority first.

You can use the `onDemandMaxTotalPrice` parameter, the `spotMaxTotalPrice` parameter, or both parameters to ensure that your fleet cost does not exceed your budget. If you set a maximum price per hour for the On-Demand Instances and Spot Instances in your request, Spot Fleet will launch instances until it reaches the maximum amount you're willing to pay. When the maximum amount you're willing to pay is reached, the fleet stops launching instances even if it hasn’t met the target capacity. If your fleet includes T instances that are configured as `unlimited`, and if their average CPU usage exceeds the baseline utilization, you will incur a charge for surplus credits. The `onDemandMaxTotalPrice` does not account for surplus credits, and, if you use surplus credits, your final cost might be higher than what you specified for `onDemandMaxTotalPrice`.
