Exemplos de código para a Amazon EC2 usando AWS SDKs

Os exemplos de código a seguir mostram como usar o Amazon Elastic Compute Cloud (AmazonEC2) com um kit de desenvolvimento de AWS software (SDK).

Ações são trechos de código de programas maiores e devem ser executadas em contexto. Embora as ações mostrem como chamar funções de serviço específicas, é possível ver as ações contextualizadas em seus devidos cenários e exemplos entre serviços.

Cenários são exemplos de código que mostram como realizar uma tarefa específica chamando várias funções dentro do mesmo serviço.
