A service management system manages scaling and migration of a plurality of services in a content management system. The service management system may maintain a plurality of services that are distributed across a plurality of clusters, each service serving a functionality in the content management system. Responsive to receiving a request to scale a service, the service management system may access dependency data describing dependencies among the plurality of services. Based on the dependency data, the service management system may determine a set of services to scale and determine a scaling sequence in which the set of services are to be scaled. The service management system may further determine other parameters for the scaling process such as scaling ratios, allocation ratios and scaling factors associated with the services and the scaling is further based on the parameters.
