# Zone Regioni AWS di utilizzo e disponibilità

## Descrivere le regioni
<a name="describe-regions"></a>

Per elencare le regioni disponibili per il tuo account, chiama il metodo di Ec2Client. `describeRegions` Restituisce [DescribeRegionsResponse](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/DescribeRegionsResponse.html). Chiamare il metodo `regions` dell'oggetto restituito per ottenere un elenco di oggetti [Region](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/Region.html) che rappresentano ciascuna regione.

## Descrivere le zone di disponibilità
<a name="describe-availability-zones"></a>

Per elencare ogni zona di disponibilità disponibile per il tuo account, chiama il metodo di Ec2Client. `describeAvailabilityZones` Restituisce [DescribeAvailabilityZonesResponse](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/DescribeAvailabilityZonesResponse.html). Chiama il suo `availabilityZones` metodo per ottenere un elenco di [AvailabilityZone](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/AvailabilityZone.html)oggetti che rappresentano ogni zona di disponibilità.

Crea Ec2Client.

```
        Ec2AsyncClient ec2AsyncClient = Ec2AsyncClient.builder()
            .region(Region.US_EAST_1)
            .build();
```

Quindi chiama describeAvailabilityZones () e recupera i risultati.

## Descrivere gli account
<a name="describe-accounts"></a>

Per elencare le informazioni EC2 relative al tuo account, chiama il metodo di Ec2Client. `describeAccountAttributes` Questo metodo restituisce un oggetto. [DescribeAccountAttributesResponse](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/DescribeAccountAttributesResponse.html) Invoca questo `accountAttributes` metodo degli oggetti per ottenere un elenco di [AccountAttribute](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/AccountAttribute.html)oggetti. È possibile scorrere l'elenco per recuperare un oggetto. `AccountAttribute`

Puoi ottenere i valori degli attributi del tuo account richiamando il metodo dell'`AccountAttribute`oggetto. `attributeValues` Questo metodo restituisce un elenco di [AccountAttributeValue](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/AccountAttributeValue.html)oggetti. È possibile scorrere questo secondo elenco per visualizzare il valore degli attributi (vedere l'esempio di codice riportato di seguito).
