Bare metal support requirements for EC2 instances.

Controls whether selected instance types must, may, or must not be bare metal variants (i.e., instances that run directly on physical hardware without a hypervisor).

Example: 

 Role infrastructureRole;
 InstanceProfile instanceProfile;
 Vpc vpc;
 ManagedInstancesCapacityProvider miCapacityProvider = ManagedInstancesCapacityProvider.Builder.create(this, "MICapacityProvider")
         .infrastructureRole(infrastructureRole)
         .ec2InstanceProfile(instanceProfile)
         .subnets(vpc.getPrivateSubnets())
         .instanceRequirements(InstanceRequirementsConfig.builder()
                 // Required: CPU and memory constraints
                 .vCpuCountMin(2)
                 .vCpuCountMax(8)
                 .memoryMin(Size.gibibytes(4))
                 .memoryMax(Size.gibibytes(32))
                 // CPU preferences
                 .cpuManufacturers(List.of(CpuManufacturer.INTEL, CpuManufacturer.AMD))
                 .instanceGenerations(List.of(InstanceGeneration.CURRENT))
                 // Instance type filtering
                 .allowedInstanceTypes(List.of("m5.*", "c5.*"))
                 // Performance characteristics
                 .burstablePerformance(BurstablePerformance.EXCLUDED)
                 .bareMetal(BareMetal.EXCLUDED)
                 // Accelerator requirements (for ML/AI workloads)

                 .acceleratorManufacturers(List.of(AcceleratorManufacturer.NVIDIA))
                 .acceleratorNames(List.of(AcceleratorName.T4, AcceleratorName.V100))
                 .acceleratorCountMin(1)
                 // Storage requirements
                 .localStorage(LocalStorage.REQUIRED)
                 .localStorageTypes(List.of(LocalStorageType.SSD))
                 .totalLocalStorageGBMin(100)
                 // Network requirements
                 .networkInterfaceCountMin(2)
                 .networkBandwidthGbpsMin(10)
                 // Cost optimization
                 .onDemandMaxPricePercentageOverLowestPrice(10)
                 .build())
         .build();

  • Enum Constant Details

    • INCLUDED

      @Stability(Stable) public static final BareMetal INCLUDED
      Bare metal instance types are allowed, but non-bare-metal (virtualized) types may also be selected.

    • REQUIRED

      @Stability(Stable) public static final BareMetal REQUIRED
      Only bare metal instance types are allowed.

      Non-bare-metal types will be excluded from selection.

    • EXCLUDED

      @Stability(Stable) public static final BareMetal EXCLUDED
      Bare metal instance types are disallowed.

      Only non-bare-metal types may be selected.

  • Method Details

    • values

      public static BareMetal[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static BareMetal valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
