// Launches the specified number of instances using an AMI for which you have
// permissions. You can specify a number of options, or leave the default options.
// The following rules apply:
//
// * [EC2-VPC] If you don't specify a subnet ID, we
// choose a default subnet from your default VPC for you. If you don't have a
// default VPC, you must specify a subnet ID in the request.
//
// * [EC2-Classic] If
// don't specify an Availability Zone, we choose one for you.
//
// * Some instance
// types must be launched into a VPC. If you do not have a default VPC, or if you
// do not specify a subnet ID, the request fails. For more information, see
// Instance types available only in a VPC
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-vpc.html#vpc-only-instance-types).
//
// *
// [EC2-VPC] All instances have a network interface with a primary private IPv4
// address. If you don't specify this address, we choose one from the IPv4 range of
// your subnet.
//
// * Not all instance types support IPv6 addresses. For more
// information, see Instance types
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html).
//
// * If
// you don't specify a security group ID, we use the default security group. For
// more information, see Security groups
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html).
//
// *
// If any of the AMIs have a product code attached for which the user has not
// subscribed, the request fails.
//
// You can create a launch template
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-launch-templates.html),
// which is a resource that contains the parameters to launch an instance. When you
// launch an instance using RunInstances, you can specify the launch template
// instead of specifying the launch parameters. To ensure faster instance launches,
// break up large requests into smaller batches. For example, create five separate
// launch requests for 100 instances each instead of one launch request for 500
// instances. An instance is ready for you to use when it's in the running state.
// You can check the state of your instance using DescribeInstances. You can tag
// instances and EBS volumes during launch, after launch, or both. For more
// information, see CreateTags and Tagging your Amazon EC2 resources
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html). Linux
// instances have access to the public key of the key pair at boot. You can use
// this key to provide secure access to the instance. Amazon EC2 public images use
// this feature to provide secure access without passwords. For more information,
// see Key pairs
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html). For
// troubleshooting, see What to do if an instance immediately terminates
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_InstanceStraightToTerminated.html),
// and Troubleshooting connecting to your instance
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html).
// We are retiring EC2-Classic. We recommend that you migrate from EC2-Classic to a
// VPC. For more information, see Migrate from EC2-Classic to a VPC
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/vpc-migrate.html) in the
// Amazon EC2 User Guide.
