Exemples de code à EC2 utiliser par Amazon AWS SDKs

Les exemples de code suivants vous montrent comment utiliser Amazon Elastic Compute Cloud (AmazonEC2) avec un kit de développement AWS logiciel (SDK).

Les actions sont des extraits de code de programmes plus larges et doivent être exécutées dans leur contexte. Alors que les actions vous indiquent comment appeler des fonctions de service individuelles, vous pouvez les voir en contexte dans leurs scénarios associés et dans des exemples interservices.

Les Scénarios sont des exemples de code qui vous montrent comment accomplir une tâche spécifique en appelant plusieurs fonctions au sein d’un même service.
