ElastiCache exemplos usando AWS CLI

Os exemplos de código a seguir mostram como realizar ações e implementar cenários comuns usando o AWS Command Line Interface with ElastiCache.

Ações são trechos de código de programas maiores e devem ser executadas em contexto. Embora as ações mostrem como chamar funções de serviço individuais, você pode ver as ações no contexto em seus cenários relacionados.

Cada exemplo inclui um link para o código-fonte completo, onde você pode encontrar instruções sobre como configurar e executar o código no contexto.
