Creación de un SDK de recursos para administradores de AWS SaaS

El siguiente ejemplo demuestra cómo crear una distribución de varios inquilino con parámetros y un certificado comodín.

Tenga en cuenta que no es necesario agregar información del certificado aquí, ya que nuestro dominio ya está cubierto por la plantilla principal.

El siguiente ejemplo demuestra cómo hacerlo con una solicitud de certificado administrado alojado en CloudFront. Esto es ideal si aún no tiene tráfico hacia el dominio. En este caso, creamos un ConnectionGroup para generar un RoutingEndpoint. A continuación, utilizamos ese RoutingEndpoint para crear registros DNS que verifiquen la propiedad del dominio y apunten a CloudFront. CloudFront servirá automáticamente un token para validar la propiedad del dominio y crear un certificado administrado.

El siguiente ejemplo demuestra cómo hacerlo con una solicitud de certificado autoadministrada. Esto es ideal si tiene tráfico hacia el dominio y no puede tolerar el tiempo de inactividad durante una migración. Al final de este ejemplo, el inquilino se creará con un estado de espera de la validación del dominio y la configuración de DNS. Siga los pasos [aquí](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/managed-cloudfront-certificates.html#complete-domain-ownership) para completar la configuración cuando se haya preparado para migrar el tráfico.
