To continue to benefit from the billing discounts provided by reserved instances, we recommend that you enable the auto-renewal feature to auto-renew reserved instances before the reserved instances expire. This topic describes how to auto-renew an existing reserved instance.
Procedure
Log on to the ECS console.
In the left-side navigation pane, choose .
Find the reserved instance that you want to auto-renew. In the Actions column, click Auto-renewal.
Read the notes, turn on Enable Auto-renewal, specify the Duration parameter, and then click OK.
(Optional) If you do not want to auto-renew a reserved instance, click Auto-renewal in the Actions column. Then, turn off Enable Auto-renewal.
