1. A method for operating a first scaling entity of a container based cloud infrastructure distributed over a plurality of geographically distributed edge sites of a network, wherein the container based cloud infrastructure provides at least one service to a user of the network, the method comprising:
determining at least one performance parameter influencing a performance how a first part of the container based cloud infrastructure provided on a first edge site of the plurality of edge sites where the first scaling entity is located provides the service to the user,
determining, based on the determined at least one performance parameter, whether a scaling of the cloud infrastructure located on at least one other edge site of the plurality of geographically distributed edge sites outside the first edge site is necessary, wherein in the affirmative:
determining an amendment of the container based cloud infrastructure at the at least one other edge site which is configured to provide the service to the user, and
triggering the determined amendment of the container cloud infrastructure at the at least one other edge site,
wherein the at least one determined performance parameter includes network latency; and
wherein the first scaling entity comprises a geographic scaling policy indicating an amendment of the container based cloud infrastructure on the first edge site and on the other edge sites outside the first edge site in dependence on the network latency and in dependence on performance requirements for the service, wherein the amendment of the container based cloud infrastructure in the at least one other edge site is determined based on the geographic scaling policy and the network latency.
