Abstract: A capacity expansion method includes obtaining a measured workload of a service of an application, obtaining an application model of the application, and obtaining a measured workload of each upper-level service of the service; determining a predicted workload of the service based on the measured workload of the service, determining the measured workload of each upper-level service of the first service, and determining a first workload ratio corresponding to a first calling relationship; and determining a predicted workload of each lower-level service based on the predicted workload of the service and determining a second workload ratio corresponding to a second calling relationship.
