// 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]parameter. All other health check settings for the load balancer use the
//	default values described in the [Health checks for your target groups]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]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] is NONE) and you use
// your own networking infrastructure, you need to configure [VPC to VPC connectivity]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]in the Refactor Spaces User
// Guide.
