  { -- | The instance type of the instance recommendation.
    instanceType :: Prelude.Maybe Prelude.Text,
    -- | The level of effort required to migrate from the current instance type
    -- to the recommended instance type.
    --
    -- For example, the migration effort is @Low@ if Amazon EMR is the inferred
    -- workload type and an Amazon Web Services Graviton instance type is
    -- recommended. The migration effort is @Medium@ if a workload type
    -- couldn\'t be inferred but an Amazon Web Services Graviton instance type

    -- and recommended instance types are of the same CPU architecture.

    -- | The performance risk of the instance recommendation option.
    --
    -- Performance risk indicates the likelihood of the recommended instance
    -- type not meeting the resource needs of your workload. Compute Optimizer
    -- calculates an individual performance risk score for each specification
    -- of the recommended instance, including CPU, memory, EBS throughput, EBS
    -- IOPS, disk throughput, disk IOPS, network throughput, and network PPS.
    -- The performance risk of the recommended instance is calculated as the
    -- maximum performance risk score across the analyzed resource
    -- specifications.
    --
    -- The value ranges from @0@ - @4@, with @0@ meaning that the recommended
    -- resource is predicted to always provide enough hardware capability. The
    -- higher the performance risk is, the more likely you should validate

    --     interface and the current instance does not. To access NVMe volumes

    -- -   __@VirtualizationType@__ — The recommended instance type uses the

    --     in the /Amazon EC2 User Guide for Windows/.
    --
    -- -   __@Architecture@__ — The CPU architecture between the recommended
    --     instance type and the current instance is different. For example,
    --     the recommended instance type might use an Arm CPU architecture and
    --     the current instance type might use a different one, such as x86.
    --     Before migrating, you should consider recompiling the software on
    --     your instance for the new architecture. Alternatively, you might

-- -   __@VirtualizationType@__ — The recommended instance type uses the
--     hardware virtual machine (HVM) virtualization type and the current
--     instance uses the paravirtual (PV) virtualization type. For more
--     information about the differences between these virtualization
--     types, see
--     <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/virtualization_types.html Linux AMI virtualization types>
--     in the /Amazon EC2 User Guide for Linux/, or
--     <https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/windows-ami-version-history.html#virtualization-types Windows AMI virtualization types>
--     in the /Amazon EC2 User Guide for Windows/.
--
-- -   __@Architecture@__ — The CPU architecture between the recommended
--     instance type and the current instance is different. For example,
--     the recommended instance type might use an Arm CPU architecture and
--     the current instance type might use a different one, such as x86.
--     Before migrating, you should consider recompiling the software on
--     your instance for the new architecture. Alternatively, you might
--     switch to an Amazon Machine Image (AMI) that supports the new
--     architecture. For more information about the CPU architecture for
--     each instance type, see
--     <http://aws.amazon.com/ec2/instance-types/ Amazon EC2 Instance Types>.
