Zone Regioni AWS di utilizzo e disponibilità

Descrivere le regioni

Per elencare le regioni disponibili per il tuo account, chiama il metodo di Ec2Client. describeRegions Restituisce DescribeRegionsResponse. Chiamare il metodo regions dell'oggetto restituito per ottenere un elenco di oggetti Region che rappresentano ciascuna regione.

Descrivere le zone di disponibilità

Per elencare ogni zona di disponibilità disponibile per il tuo account, chiama il metodo di Ec2Client. describeAvailabilityZones Restituisce DescribeAvailabilityZonesResponse. Chiama il suo availabilityZones metodo per ottenere un elenco di AvailabilityZoneoggetti 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

Per elencare le informazioni EC2 relative al tuo account, chiama il metodo di Ec2Client. describeAccountAttributes Questo metodo restituisce un oggetto. DescribeAccountAttributesResponse Invoca questo accountAttributes metodo degli oggetti per ottenere un elenco di AccountAttributeoggetti. È possibile scorrere l'elenco per recuperare un oggetto. AccountAttribute

Puoi ottenere i valori degli attributi del tuo account richiamando il metodo dell'AccountAttributeoggetto. attributeValues Questo metodo restituisce un elenco di AccountAttributeValueoggetti. È possibile scorrere questo secondo elenco per visualizzare il valore degli attributi (vedere l'esempio di codice riportato di seguito).
