# Esempi di codice per l'utilizzo di Elastic Beanstalk AWS SDKs
<a name="elastic-beanstalk_code_examples"></a>

I seguenti esempi di codice mostrano come utilizzarlo AWS Elastic Beanstalk con un kit di sviluppo AWS software (SDK).

Le *azioni* sono estratti di codice da programmi più grandi e devono essere eseguite nel contesto. Sebbene le azioni mostrino come richiamare le singole funzioni del servizio, è possibile visualizzarle contestualizzate negli scenari correlati.
