A user purchases the elastic scaling service, and the bandwidth can be adjusted on demand through elastic scaling. When the service increases, the bandwidth is expanded, and when the service decreases, the bandwidth is reduced, which enhances the cost management of the service system. Currently, the scaling strategies supported by the auto scaling service mainly include: () strategy, timing strategy, and periodic strategy. Users can adjust the IP bandwidth on demand by selecting different scaling policies according to the actual situation.
