A method and system of deployment of a virtualized service on a cloud infrastructure while taking into consideration variability/elasticity of the cloud resources are described. A first service function specification is selected. Candidate computing systems and candidate links are determined. The determination of the candidates is performed based on the availability and characteristics of the computing systems and the network resources in the cloud infrastructure which includes varying characteristics. A first computing system and one or more links are determined from the candidates for placing the first service function in the cloud infrastructure.

Joint consideration of service function placement and definition for deployment of a virtualized service

A method and system of deployment of a virtualized service on a cloud infrastructure are described. A first service function specification of a first service function is selected. A determination of a set of the computing systems and a set of the links is performed based on availability and characteristics of the computing systems and the network resources in the cloud infrastructure, A selection of a first computing system to be assigned to host the first service function and links is performed based on the first service function specification. In response to determining that there is one or more the service functions that are not yet assigned, the selection of the service function and the determination of the computing system and links are repeated for each remaining functions until all of service function are assigned to computing and networking resources in the cloud infrastructure.
