    # @overload initialize(options)
    #   @param [Hash] options
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials. This can be an instance of any one of the
    #     following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::SharedCredentials` - Used for loading credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     When `:credentials` are not configured directly, the following
    #     locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #     * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
    #     * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2 IMDS instance profile - When used by default, the timeouts are
    #       very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentails` to enable retries and extended
    #       timeouts.
    #
    #   @option options [required, String] :region
    #     The AWS region to connect to.  The configured `:region` is
    #     used to determine the service `:endpoint`. When not passed,

    # Creates an Application Load Balancer or a Network Load Balancer.
    #
    # When you create a load balancer, you can specify security groups,
    # public subnets, IP address type, and tags. Otherwise, you could do so
    # later using SetSecurityGroups, SetSubnets, SetIpAddressType, and
    # AddTags.
    #
    # To create listeners for your load balancer, use CreateListener. To
    # describe your current load balancers, see DescribeLoadBalancers. When
    # you are finished with a load balancer, you can delete it using
    # DeleteLoadBalancer.
    #
    # For limit information, see [Limits for Your Application Load
    # Balancer][1] in the *Application Load Balancers Guide* and [Limits for
    # Your Network Load Balancer][2] in the *Network Load Balancers Guide*.
    #
    # This operation is idempotent, which means that it completes at most
    # one time. If you attempt to create multiple load balancers with the
    # same settings, each call succeeds.
    #
    # For more information, see [Application Load Balancers][3] in the
    # *Application Load Balancers Guide* and [Network Load Balancers][4] in

    #   The IDs of the public subnets. You can specify only one subnet per
    #   Availability Zone. You must specify either subnets or subnet mappings.
    #
    #   \[Application Load Balancers\] You must specify subnets from at least

    #   \[Network Load Balancers\] You can specify subnets from one or more
    #   Availability Zones.
    #
    # @option params [Array<Types::SubnetMapping>] :subnet_mappings
    #   The IDs of the public subnets. You can specify only one subnet per
    #   Availability Zone. You must specify either subnets or subnet mappings.
    #
    #   \[Application Load Balancers\] You must specify subnets from at least
    #   two Availability Zones. You cannot specify Elastic IP addresses for
    #   your subnets.
    #
    #   \[Network Load Balancers\] You can specify subnets from one or more
    #   Availability Zones. You can specify one Elastic IP address per subnet.
    #
    # @option params [Array<String>] :security_groups
    #   \[Application Load Balancers\] The IDs of the security groups for the
    #   load balancer.
    #
    # @option params [String] :scheme
    #   The nodes of an Internet-facing load balancer have public IP
    #   addresses. The DNS name of an Internet-facing load balancer is
    #   publicly resolvable to the public IP addresses of the nodes.
    #   Therefore, Internet-facing load balancers can route requests from
    #   clients over the internet.
    #
    #   The nodes of an internal load balancer have only private IP addresses.
    #   The DNS name of an internal load balancer is publicly resolvable to
    #   the private IP addresses of the nodes. Therefore, internal load
    #   balancers can only route requests from clients with access to the VPC
    #   for the load balancer.
    #
    #   The default is an Internet-facing load balancer.
    #
    # @option params [Array<Types::Tag>] :tags
    #   One or more tags to assign to the load balancer.
    #
    # @option params [String] :type
    #   The type of load balancer. The default is `application`.
    #
    # @option params [String] :ip_address_type
    #   \[Application Load Balancers\] The type of IP addresses used by the
    #   subnets for your load balancer. The possible values are `ipv4` (for
    #   IPv4 addresses) and `dualstack` (for IPv4 and IPv6 addresses).
    #   Internal load balancers must use `ipv4`.

    #
    # @option params [required, String] :name
    #   The name of the target group.
    #
    #   This name must be unique per region per account, can have a maximum of
    #   32 characters, must contain only alphanumeric characters or hyphens,
    #   and must not begin or end with a hyphen.
    #
    # @option params [String] :protocol
    #   The protocol to use for routing traffic to the targets. For
    #   Application Load Balancers, the supported protocols are HTTP and
    #   HTTPS. For Network Load Balancers, the supported protocols are TCP and
    #   TLS. If the target is a Lambda function, this parameter does not
    #   apply.
    #
    # @option params [Integer] :port
    #   The port on which the targets receive traffic. This port is used
    #   unless you specify a port override when registering the target. If the
    #   target is a Lambda function, this parameter does not apply.
    #
    # @option params [String] :vpc_id
    #   The identifier of the virtual private cloud (VPC). If the target is a
    #   Lambda function, this parameter does not apply.
    #
    # @option params [String] :health_check_protocol
    #   The protocol the load balancer uses when performing health checks on
    #   targets. For Application Load Balancers, the default is HTTP. For
    #   Network Load Balancers, the default is TCP. The TCP protocol is
    #   supported for health checks only if the protocol of the target group
    #   is TCP or TLS. The TLS protocol is not supported for health checks.
    #
    # @option params [String] :health_check_port
    #   The port the load balancer uses when performing health checks on
    #   targets. The default is `traffic-port`, which is the port on which
    #   each target receives traffic from the load balancer.
    #
    # @option params [Boolean] :health_check_enabled
    #   Indicates whether health checks are enabled. If the target type is
    #   `instance` or `ip`, the default is `true`. If the target type is
    #   `lambda`, the default is `false`.
    #
    # @option params [String] :health_check_path
    #   \[HTTP/HTTPS health checks\] The ping path that is the destination on
    #   the targets for health checks. The default is /.
    #
    # @option params [Integer] :health_check_interval_seconds
    #   The approximate amount of time, in seconds, between health checks of
    #   an individual target. For Application Load Balancers, the range is
    #   5–300 seconds. For Network Load Balancers, the supported values are 10
    #   or 30 seconds. If the target type is `instance` or `ip`, the default
    #   is 30 seconds. If the target type is `lambda`, the default is 35
    #   seconds.
    #
    # @option params [Integer] :health_check_timeout_seconds
    #   The amount of time, in seconds, during which no response from a target
    #   means a failed health check. For Application Load Balancers, the range
    #   is 2–120 seconds and the default is 5 seconds if the target type is
    #   `instance` or `ip` and 30 seconds if the target type is `lambda`. For
    #   Network Load Balancers, this is 10 seconds for TCP and HTTPS health
    #   checks and 6 seconds for HTTP health checks.
    #
    # @option params [Integer] :healthy_threshold_count
    #   The number of consecutive health checks successes required before
    #   considering an unhealthy target healthy. For Application Load
    #   Balancers, the default is 5. For Network Load Balancers, the default
    #   is 3.
    #
    # @option params [Integer] :unhealthy_threshold_count
    #   The number of consecutive health check failures required before
    #   considering a target unhealthy. For Application Load Balancers, the
    #   default is 2. For Network Load Balancers, this value must be the same
    #   as the healthy threshold count.
    #
    # @option params [Types::Matcher] :matcher
    #   \[HTTP/HTTPS health checks\] The HTTP codes to use when checking for a
    #   successful response from a target.
    #
    # @option params [String] :target_type
    #   The type of target that you must specify when registering targets with
    #   this target group. You can't specify targets for a target group using
    #   more than one target type.
    #
    #   * `instance` - Targets are specified by instance ID. This is the
    #     default value.
    #
    #   * `ip` - Targets are specified by IP address. You can specify IP
    #     addresses from the subnets of the virtual private cloud (VPC) for
    #     the target group, the RFC 1918 range (10.0.0.0/8, 172.16.0.0/12, and
    #     192.168.0.0/16), and the RFC 6598 range (100.64.0.0/10). You can't
    #     specify publicly routable IP addresses.
    #

    # Polls an API operation until a resource enters a desired state.
    #
    # ## Basic Usage
    #
    # A waiter will call an API operation until:
    #
    # * It is successful
    # * It enters a terminal state
    # * It makes the maximum number of attempts
    #
    # In between attempts, the waiter will sleep.
    #
    #     # polls in a loop, sleeping between attempts
    #     client.wait_until(waiter_name, params)
    #
    # ## Configuration
    #
    # You can configure the maximum number of polling attempts, and the
    # delay (in seconds) between each polling attempt. You can pass
    # configuration as the final arguments hash.
    #
    #     # poll for ~25 seconds
    #     client.wait_until(waiter_name, params, {
    #       max_attempts: 5,
    #       delay: 5,
    #     })
    #
    # ## Callbacks
    #
    # You can be notified before each polling attempt and before each
    # delay. If you throw `:success` or `:failure` from these callbacks,
    # it will terminate the waiter.
    #
    #     started_at = Time.now
    #     client.wait_until(waiter_name, params, {
    #
    #       # disable max attempts
    #       max_attempts: nil,
    #
    #       # poll for 1 hour, instead of a number of attempts
    #       before_wait: -> (attempts, response) do
    #         throw :failure if Time.now - started_at > 3600
    #       end
    #     })
    #
    # ## Handling Errors
    #
    # When a waiter is unsuccessful, it will raise an error.
    # All of the failure errors extend from
    # {Aws::Waiters::Errors::WaiterFailed}.
    #
    #     begin
    #       client.wait_until(...)
    #     rescue Aws::Waiters::Errors::WaiterFailed
    #       # resource did not enter the desired state in time
    #     end
    #
    # ## Valid Waiters
    #
    # The following table lists the valid waiter names, the operations they call,
    # and the default `:delay` and `:max_attempts` values.
    #
