// Creates a new, empty file system. The operation requires a creation token
// in the request that Amazon EFS uses to ensure idempotent creation (calling
// the operation with same creation token has no effect). If a file system does
// not currently exist that is owned by the caller's AWS account with the specified
// creation token, this operation does the following:
//
//  Creates a new, empty file system. The file system will have an Amazon EFS
// assigned ID, and an initial lifecycle state "creating".   Returns with the
// description of the created file system.   Otherwise, this operation returns
// a FileSystemAlreadyExists error with the ID of the existing file system.
//
// For basic use cases, you can use a randomly generated UUID for the creation
// token.  The idempotent operation allows you to retry a CreateFileSystem call
// without risk of creating an extra file system. This can happen when an initial
// call fails in a way that leaves it uncertain whether or not a file system
// was actually created. An example might be that a transport level timeout
// occurred or your connection was reset. As long as you use the same creation
// token, if the initial call had succeeded in creating a file system, the client
// can learn of its existence from the FileSystemAlreadyExists error.
//
// The CreateFileSystem call returns while the file system's lifecycle state
// is still "creating". You can check the file system creation status by calling
// the DescribeFileSystems API, which among other things returns the file system
// state.  After the file system is fully created, Amazon EFS sets its lifecycle
// state to "available", at which point you can create one or more mount targets
// for the file system (CreateMountTarget) in your VPC. You mount your Amazon
// EFS file system on an EC2 instances in your VPC via the mount target. For

// Creates a mount target for a file system. You can then mount the file system
// on EC2 instances via the mount target.
//
// You can create one mount target in each Availability Zone in your VPC. All
// EC2 instances in a VPC within a given Availability Zone share a single mount
// target for a given file system. If you have multiple subnets in an Availability
// Zone, you create a mount target in one of the subnets. EC2 instances do not
// need to be in the same subnet as the mount target in order to access their
// file system. For more information, see Amazon EFS: How it Works (http://docs.aws.amazon.com/efs/latest/ug/how-it-works.html).
//
// In the request, you also specify a file system ID for which you are creating
// the mount target and the file system's lifecycle state must be "available"
// (see DescribeFileSystems).
//
//  In the request, you also provide a subnet ID, which serves several purposes:
//
//  It determines the VPC in which Amazon EFS creates the mount target. It
// determines the Availability Zone in which Amazon EFS creates the mount target.
//  It determines the IP address range from which Amazon EFS selects the IP
// address of the mount target if you don't specify an IP address in the request.
//   After creating the mount target, Amazon EFS returns a response that includes,
// a MountTargetId and an IpAddress. You use this IP address when mounting the
// file system in an EC2 instance. You can also use the mount target's DNS name
// when mounting the file system. The EC2 instance on which you mount the file
// system via the mount target can resolve the mount target's DNS name to its
// IP address. For more information, see How it Works: Implementation Overview
// (http://docs.aws.amazon.com/efs/latest/ug/how-it-works.html#how-it-works-implementation).
//
//  Note that you can create mount targets for a file system in only one VPC,
// and there can be only one mount target per Availability Zone. That is, if
// the file system already has one or more mount targets created for it, the
// request to add another mount target must meet the following requirements:
//
//   The subnet specified in the request must belong to the same VPC as the
// subnets of the existing mount targets.
//
//  The subnet specified in the request must not be in the same Availability
// Zone as any of the subnets of the existing mount targets.  If the request
// satisfies the requirements, Amazon EFS does the following:
//
//  Creates a new mount target in the specified subnet.  Also creates a new
// network interface in the subnet as follows:  If the request provides an IpAddress,
// Amazon EFS assigns that IP address to the network interface. Otherwise, Amazon
// EFS assigns a free address in the subnet (in the same way that the Amazon
// EC2 CreateNetworkInterface call does when a request does not specify a primary
// private IP address). If the request provides SecurityGroups, this network
// interface is associated with those security groups. Otherwise, it belongs
// to the default security group for the subnet's VPC. Assigns the description
// "Mount target fsmt-id for file system fs-id" where fsmt-id is the mount target
// ID, and fs-id is the FileSystemId. Sets the requesterManaged property of
// the network interface to "true", and the requesterId value to "EFS".  Each
// Amazon EFS mount target has one corresponding requestor-managed EC2 network
// interface. After the network interface is created, Amazon EFS sets the NetworkInterfaceId
// field in the mount target's description to the network interface ID, and
// the IpAddress field to its address. If network interface creation fails,
// the entire CreateMountTarget operation fails.
//
//   The CreateMountTarget call returns only after creating the network interface,
// but while the mount target state is still "creating". You can check the mount
// target creation status by calling the DescribeFileSystems API, which among
// other things returns the mount target state. We recommend you create a mount
// target in each of the Availability Zones. There are cost considerations for
// using a file system in an Availability Zone through a mount target created
// in another Availability Zone. For more information, go to Amazon EFS (http://aws.amazon.com/efs/)
// product detail page. In addition, by always using a mount target local to
// the instance's Availability Zone, you eliminate a partial failure scenario;
// if the Availability Zone in which your mount target is created goes down,
// then you won't be able to access your file system through that mount target.
