But when running smoothly and without hot events, the pressure is relatively low and not requiring as much ECS. Which of the following scenarios can help reduce costs for this business? Multiple selection

Options :

A :

Purchase an on-demand ECS instance and manually scale out during peak service hours, delete the redundant instances

B : and use AutoScali. The periodic policy of the nG service is scaled regularly to cope with service peaks

C :

Purchasing Reserved Instances (on-demand packages) can save fees when creating and deleting ECS instances (compared to the subscription cycle).

D :

Use the alarm policy of AutoSc a ling service to scale out the capacity horizontally when a high ECS load is detected: Detected When the ECS load is low, it can be scaled down to save costs

Answer: C,D
