The scaling arrangement determines, at the global auto-scaler (131) of the scaling arrangement (13), to perform one or more actions based on at least resource information stored at the global auto-scaler; wherein the resource information is associated with resources structured in multiple clouds comprising one or more local clusters of resources. The one or more actions comprise modifying a parameter related to at least one of the resources of the multiple clouds. The scaling arrangement sends a modifying request to at least one local auto-scaler out of the one or more local auto-scalers (132), requesting to perform one or more operations related to the modified parameter. ## Claims ### Claim 1 A method performed by a scaling arrangement for managing resources in a communication network associated with a multiple cloud infrastructure, wherein the scaling arrangement comprises a global auto-scaler and one or more local auto-scalers, the method comprising: determining, at the global auto-scaler of the scaling arrangement, to perform one or more actions based on at least resource information stored at the global auto-scaler;
