What Is the Billing Policy of APM?
APM supports both pay-per-use and package billing. For more information, see APM Pricing Details. The two billing modes can be used at the same time. If you use more instances than those included in a package, you will be billed on a pay-per-use basis for the excess instances used. If you use APM without purchasing any package, you will be billed on a pay-per-use basis for all instances.
