    @Generated("software.amazon.awssdk:codegen")
public final class InstanceRequirements
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<InstanceRequirements.Builder,​InstanceRequirements>

    The attributes for the instance types for a mixed instances policy. Amazon EC2 Auto Scaling uses your specified requirements to identify instance types. Then, it uses your On-Demand and Spot allocation strategies to launch instances from these instance types.

    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 Auto Scaling 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.

    You must specify VCpuCount and MemoryMiB. All other attributes are optional. Any unspecified optional attribute is set to its default.

    For more information, see Creating an Auto Scaling group using attribute-based instance type selection in the Amazon EC2 Auto Scaling User Guide. For help determining which instance types match your attributes before you apply them to your Auto Scaling group, see Preview instance types with specified attributes in the Amazon EC2 User Guide for Linux Instances.

      • cpuManufacturers

        public final List<CpuManufacturer> cpuManufacturers()

        Lists which specific CPU manufacturers to include.

        • For instance types with Intel CPUs, specify intel.

        • For instance types with AMD CPUs, specify amd.

        • For instance types with Amazon Web Services CPUs, specify amazon-web-services.

        Don't confuse the CPU hardware manufacturer with the CPU hardware architecture. Instances will be launched with a compatible CPU architecture based on the Amazon Machine Image (AMI) that you specify in your launch template.

        Default: Any manufacturer

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasCpuManufacturers() method.

        Returns:
        Lists which specific CPU manufacturers to include.

        • For instance types with Intel CPUs, specify intel.

      • hasCpuManufacturers

        public final boolean hasCpuManufacturers()
        For responses, this returns true if the service returned a value for the CpuManufacturers property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • hasExcludedInstanceTypes

        public final boolean hasExcludedInstanceTypes()
        For responses, this returns true if the service returned a value for the ExcludedInstanceTypes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • excludedInstanceTypes

        public final List<String> excludedInstanceTypes()

        The instance types to exclude. You can use strings with one or more wild cards, represented by an asterisk ( *), to exclude an instance family, type, size, or generation. The following are examples: m5.8xlarge, c5*.*, m5a.*, r*, *3*.

        For example, if you specify c5*, you are excluding the entire C5 instance family, which includes all C5a and C5n instance types. If you specify m5a.*, Amazon EC2 Auto Scaling will exclude all the M5a instance types, but not the M5n instance types.

        If you specify ExcludedInstanceTypes, you can't specify AllowedInstanceTypes.

        Default: No excluded instance types

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasExcludedInstanceTypes() method.

        Default: Any accelerator

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAcceleratorNames() method.

        Returns:
        Lists the accelerators that must be on an instance type.

      • hasAcceleratorNames

        public final boolean hasAcceleratorNames()
        For responses, this returns true if the service returned a value for the AcceleratorNames property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • acceleratorNamesAsStrings

        public final List<String> acceleratorNamesAsStrings()

        Lists the accelerators that must be on an instance type.

        • For instance types with NVIDIA A100 GPUs, specify a100.

        • For instance types with NVIDIA V100 GPUs, specify v100.

      • acceleratorTotalMemoryMiB

        public final AcceleratorTotalMemoryMiBRequest acceleratorTotalMemoryMiB()

        The minimum and maximum total memory size for the accelerators on an instance type, in MiB.

        Default: No minimum or maximum limits

        Returns:
        The minimum and maximum total memory size for the accelerators on an instance type, in MiB.

        Default: No minimum or maximum limits

      • networkBandwidthGbps

        public final NetworkBandwidthGbpsRequest networkBandwidthGbps()

        The minimum and maximum amount of network bandwidth, in gigabits per second (Gbps).

        Default: No minimum or maximum limits

        Returns:
        The minimum and maximum amount of network bandwidth, in gigabits per second (Gbps).

        Default: No minimum or maximum limits

      • hasAllowedInstanceTypes

        public final boolean hasAllowedInstanceTypes()
        For responses, this returns true if the service returned a value for the AllowedInstanceTypes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • allowedInstanceTypes

        public final List<String> allowedInstanceTypes()

        The instance types to apply your specified attributes against. All other instance types are ignored, even if they match your specified attributes.

        You can use strings with one or more wild cards, represented by an asterisk (*), to allow an instance type, size, or generation. The following are examples: m5.8xlarge, c5*.*, m5a.*, r*, *3*.

        For example, if you specify c5*, Amazon EC2 Auto Scaling will allow the entire C5 instance family, which includes all C5a and C5n instance types. If you specify m5a.*, Amazon EC2 Auto Scaling will allow all the M5a instance types, but not the M5n instance types.

        If you specify AllowedInstanceTypes, you can't specify ExcludedInstanceTypes.

        Default: All instance types

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAllowedInstanceTypes() method.
