Ejemplo 1: Para detener una EC2 instancia de Amazon

El siguiente stop-instances ejemplo detiene la instancia EBS respaldada por Amazon especificada.

Salida:

    "StoppingInstances": [
        {

Ejemplo 2: Para hibernar una instancia de Amazon EC2

En el siguiente stop-instances ejemplo, se hiberna la instancia EBS respaldada por Amazon si la instancia está habilitada para la hibernación y cumple los requisitos previos de hibernación. Luego de que la instancia sea puesta en hibernación, la instancia se detiene.

aws ec2 stop-instances \
    --instance-ids i-1234567890abcdef0 \
    --hibernate

Salida:

    "StoppingInstances": [
        {
            "CurrentState": {
                "Code": 64,
