When you no longer need Server Load Balancer, delete the corresponding instance to avoid additional charges. When deleting the Server Load Balancer instance, the backend ECS will not be deleted or affected.
Note: After the Server Load Balancer instance is released, the backend ECS instances are still running. If you want to release the ECS instances, refer to Release an instance.
Log on to the ECS console.
On the Instance Management page, select the region where the instance is located.
Select the target instance and click Release Settings.
In the Release Settings dialog, select Release Now or Timed Release.
If you select Timed Release, select the time to release the instance.
Click Next Step and click Confirm to finish.
