When you no longer need a stack group or the stack instances in the stack group, you can delete the stack group and the resources associated with the stack group.
- Log on to the Resource Orchestration Service (ROS) console.
- In the left-side navigation pane, click Stack Groups.
- In the upper-left corner, select the region where your stack group is deployed from the drop-down list.
- On the Stack Groups page, find the stack group and click Delete in the Actions column.
- Click OK.
