# Service-specific cambios

## Cambios en Amazon S3
<a name="s3-operations-name"></a>

SDK para Java 2.x deshabilita el acceso anónimo de forma predeterminada. Por lo tanto, debe habilitar el acceso anónimo mediante el `AnonymousCredentialsProvider`.

### Cambios en nombres de operaciones
<a name="s3-op-name-changes"></a>

Muchos de los nombres de las operaciones del Amazon S3 cliente han cambiado en la versión AWS SDK para Java 2.x. En la versión 1.x, el Amazon S3 cliente no se genera directamente desde la API del servicio. Esto se traduce en una incoherencia entre las operaciones de SDK y la API de servicio. En la versión 2.x, ahora generamos el Amazon S3 cliente para que sea más coherente con la API del servicio.

En la tabla siguiente se muestran los nombres de operaciones en las dos versiones.

## Cambios en Amazon SNS
<a name="sns-changes"></a>

De forma predeterminada, un cliente de SNS solo envía solicitudes a la región para la que está configurado. Para dirigirse a una región diferente, utilice un cliente independiente por región.

## Cambios en Amazon SQS
<a name="sqs-changes"></a>

De forma predeterminada, un cliente de SQS solo envía solicitudes a la región para la que está configurado. Para dirigirse a una región diferente, utilice un cliente independiente por región.

## Cambios en Amazon RDS

El SDK para Java 2.x utiliza `RdsUtilities#generateAuthenticationToken` en lugar de la clase `RdsIamAuthTokenGenerator` de 1.x.
