Abstract: In general, techniques are described for selecting types of switches and corresponding input/output methods for virtualized network functions (VNFs) of a network service and selecting one or more host computing devices to host the VNFs for the network service to realize the selected types of switches and corresponding input/output methods for the VNFs. For example, a controller that performs aspects of NFV management and orchestration (MANO) receives requirements for a network service to be provisioned in the NFVI. Based on the requirements for the network service, which may specify one or VNFs and may specify individual requirements for each VNF, the controller selects a type of switch and corresponding input/output method for each VNF.

Abstract: Techniques are described for dynamically distributing entity monitoring assignments to a plurality of monitoring agents. In one example, processors of a co-location facility execute a plurality of network services monitoring agents. A first monitoring agent of the plurality of monitoring agents transmits instructions to a messaging service, causing the messaging service to dequeue, from a queue, a first message of a plurality of messages, wherein the first message describes a first network services entity of a plurality of network service entities. The monitoring agent transmits, to the first monitoring agent, the first message. The first monitoring agent retrieves, from the first network services entity described by the first message, performance and health metrics for the first network services entity. The first monitoring agent transmits, to the messaging service and for transmission to a database of the co-location facility, the performance and health metrics for the first network services entity.
