// Creates an Amazon Web Services Migration Hub Refactor Spaces route. The account
// owner of the service resource is always the environment owner, regardless of
// which account creates the route. Routes target a service in the application. If
// an application does not have any routes, then the first route must be created as
// a DEFAULT RouteType . When created, the default route defaults to an active
// state so state is not a required input. However, like all other state values the
// state of the default route can be updated after creation, but only when all
// other routes are also inactive. Conversely, no route can be active without the
// default route also being active. When you create a route, Refactor Spaces
// configures the Amazon API Gateway to send traffic to the target service as
// follows:
//   - URL Endpoints If the service has a URL endpoint, and the endpoint resolves
//     to a private IP address, Refactor Spaces routes traffic using the API Gateway
//     VPC link. If a service endpoint resolves to a public IP address, Refactor Spaces
//     routes traffic over the public internet. Services can have HTTP or HTTPS URL
//     endpoints. For HTTPS URLs, publicly-signed certificates are supported. Private
//     Certificate Authorities (CAs) are permitted only if the CA's domain is also
//     publicly resolvable. Refactor Spaces automatically resolves the public Domain
//     Name System (DNS) names that are set in CreateService:UrlEndpoint when you
//     create a service. The DNS names resolve when the DNS time-to-live (TTL) expires,
//     or every 60 seconds for TTLs less than 60 seconds. This periodic DNS resolution
//     ensures that the route configuration remains up-to-date. One-time health check A
//     one-time health check is performed on the service when either the route is
//     updated from inactive to active, or when it is created with an active state. If
//     the health check fails, the route transitions the route state to FAILED , an
//     error code of SERVICE_ENDPOINT_HEALTH_CHECK_FAILURE is provided, and no
//     traffic is sent to the service. For private URLs, a target group is created on
//     the Network Load Balancer and the load balancer target group runs default target
//     health checks. By default, the health check is run against the service endpoint
//     URL. Optionally, the health check can be performed against a different protocol,
//     port, and/or path using the CreateService:UrlEndpoint (https://docs.aws.amazon.com/migrationhub-refactor-spaces/latest/APIReference/API_CreateService.html#migrationhubrefactorspaces-CreateService-request-UrlEndpoint)
//     parameter. All other health check settings for the load balancer use the default
//     values described in the Health checks for your target groups (https://docs.aws.amazon.com/elasticloadbalancing/latest/application/target-group-health-checks.html)
//     in the Elastic Load Balancing guide. The health check is considered successful
//     if at least one target within the target group transitions to a healthy state.
//   - Lambda function endpoints If the service has an Lambda function endpoint,
//     then Refactor Spaces configures the Lambda function's resource policy to allow
//     the application's API Gateway to invoke the function. The Lambda function state
//     is checked. If the function is not active, the function configuration is updated
//     so that Lambda resources are provisioned. If the Lambda state is Failed , then
//     the route creation fails. For more information, see the
//     GetFunctionConfiguration's State response parameter (https://docs.aws.amazon.com/lambda/latest/dg/API_GetFunctionConfiguration.html#SSS-GetFunctionConfiguration-response-State)
//     in the Lambda Developer Guide. A check is performed to determine that a Lambda
//     function with the specified ARN exists. If it does not exist, the health check
//     fails. For public URLs, a connection is opened to the public endpoint. If the
//     URL is not reachable, the health check fails.
//
// Environments without a network bridge When you create environments without a
// network bridge ( CreateEnvironment:NetworkFabricType (https://docs.aws.amazon.com/migrationhub-refactor-spaces/latest/APIReference/API_CreateEnvironment.html#migrationhubrefactorspaces-CreateEnvironment-request-NetworkFabricType)
// is NONE) and you use your own networking infrastructure, you need to configure
// VPC to VPC connectivity (https://docs.aws.amazon.com/whitepapers/latest/aws-vpc-connectivity-options/amazon-vpc-to-amazon-vpc-connectivity-options.html)
// between your network and the application proxy VPC. Route creation from the
// application proxy to service endpoints will fail if your network is not
// configured to connect to the application proxy VPC. For more information, see
// Create a route (https://docs.aws.amazon.com/migrationhub-refactor-spaces/latest/userguide/getting-started-create-role.html)
// in the Refactor Spaces User Guide.
