# Service-specific modifiche
<a name="migration-service-changes"></a>

## Modifiche ad Amazon S3
<a name="s3-operations-name"></a>

SDK for Java 2.x disabilita l'accesso anonimo per impostazione predefinita. Di conseguenza, è necessario abilitare l'accesso anonimo utilizzando. `AnonymousCredentialsProvider`

### Modifiche al nome dell'operazione
<a name="s3-op-name-changes"></a>

Molti dei nomi delle operazioni per il Amazon S3 client sono cambiati nella versione AWS SDK per Java 2.x. Nella versione 1.x, il Amazon S3 client non viene generato direttamente dall'API del servizio. Questo provocava incoerenze tra l'API di servizio e le operazioni SDK. Nella versione 2.x, ora generiamo il Amazon S3 client in modo che sia più coerente con l'API del servizio.

La tabella seguente mostra i nomi delle operazioni nelle due versioni.

## Modifiche ad Amazon SNS
<a name="sns-changes"></a>

Per impostazione predefinita, un client SNS invia richieste solo alla regione per cui è configurato. Per scegliere come target una regione diversa, utilizza un client separato per regione.
