In an example, a system includes a first cloud exchange network for a first cloud exchange, the first cloud exchange network located within a first data center and configured with a first dedicated virtual gateway, the first dedicated virtual gateway configured to interface with a first virtual connector to a customer network, with a second virtual connector to a first cloud service provider (CSP) network, and with a third virtual connector to a second CSP network. Network traffic among the customer network, the first CSP network, and the second CSP network is routed through the first dedicated virtual gateway. The first dedicated virtual gateway dynamically polices the network traffic based on an aggregate bandwidth subscription configured in the first cloud exchange network that limits a total bandwidth that may be used over the first cloud exchange network between the customer network, the first CSP network, and the second CSP network.

Techniques for virtualized network functions (VNFs) that provide for domain isolation of networks coupled to the VNF are described. A virtual network function (VNF) includes a cloud virtual domain coupling the VNF to a cloud service, a management virtual domain coupling the VNF to a management service, and an external virtual domain having a public Internet Protocol (IP) address. The external virtual domain receives an authentication request providing access credentials for a VNF customer from a cloud client device, provides the authentication request to the management service via the management virtual domain, receives an authentication response from the management service, and, in response to determining that the VNF customer access credentials are valid, initiates application of a policy that allows the cloud client device to configure the cloud virtual domain or the cloud service and disallows configuration of the external virtual domain and the management virtual domain.

In general, techniques are described for a hierarchical, distributed DHCP system for managing IP address assignment among distributed networks of computing devices. For example, a system may include a central DHCP server configured to manage a plurality of distributed DHCP servers, each distributed DHCP server configured to perform DHCP using IP addresses allocated from a common prefix for a tenant associated with computing devices managed by multiple DHCP servers. The central DHCP server allocates IP addresses to the distributed DHCP servers, e.g., on an on-demand basis from the common pool and may handle concurrent requests for IP addresses from distributed DHCP servers. Each of the distributed DHCP servers may store records for IP addresses and media access control (MAC) addresses for computing devices managed by that distributed DHCP server, and the DHCP servers may send these records to the central DHCP server to facilitate IP assignment coherency.

Techniques for tenant-driven dynamic resource allocation in network functions virtualization infrastructure (NFVI). In one example, an orchestration system is operated by a data center provider for a data center and that orchestration system comprises processing circuitry coupled to a memory; logic stored in the memory and configured for execution by the processing circuitry, wherein the logic is operative to: compute an aggregate bandwidth for a plurality of flows associated with a tenant of the data center provider and processed by a virtual network function, assigned to the tenant, executing on a server of the data center; and modify, based on the aggregate bandwidth, an allocation of compute resources of the server executing the virtual network function.
