A method is described for installing a virtualized network function. The method is implemented in a service operating entity, and contributes to the implementation of a communications service, in a first data center of a group of data centers of a virtualized communications architecture, on the basis of a profile defined by a set of virtualized network function placement parameters specific to the type of virtualized network function. The profile, obtained from a profile management entity, is used to determine the first data center of the group. The identifier of the data center is then added to the profile and is transmitted to an administration entity of the virtualized architecture with a request for installation of the virtualized function in the determined first data center.
