Abstract: Techniques for exposing a subset of hosts on an overlay network, without exposing another subset of hosts on the overlay network, are disclosed. A component associated with an overlay network exposes a subset of hosts on the overlay network to components external to the overlay network. The component exposes the subset of hosts by distributing a mapping between (a) the hosts to-be-exposed and (b) the substrate addresses associated with the hosts. Alternatively, a component external to an overlay network exposes a subset of hosts on the overlay network to additional components external to the overlay network. The component exposes the subset of hosts by distributing a mapping between (a) the hosts to-be-exposed and (b) a substrate address associated with the particular component. In either embodiment, a mapping for hosts to-be-hidden is not distributed.

Abstract: Operations include determining billing for data being transmitted out of an Autonomous System (AS). An internal node in the AS determines billing for a packet transmitted out of the AS based at least on an egress path of the packet. The packet is received at the internal node in the AS The internal node selects an egress path of the packet based on one or more characteristics of the packet. The egress path is mapped directly or indirectly to a billing counter. The billing counter is incremented based on (a) the transmission of the packet on the overlay network to the egress gateway and (b) transmission of the packet out of the AS on the selected egress path.

Abstract: Operations include executing operations across different third-party computing clouds provided by different vendors. A cloud discovery process allows for a virtual machine, executing on a computing cloud, to discover resources on a different computing cloud provided by a different vendor. The cloud discovery process is implemented by one or more cloud agents executing within third-party clouds. A cloud agent, corresponding to a third-party computing cloud, may use a cross-cloud repository that is maintained by a tenant to discover resources in other third-party computing clouds provided by different vendors. An Application Programming Interface (API) for accessing a particular third-party computing cloud may be exposed to a cloud agent of another third-party computing cloud provided by a different vendor. The cloud agent may trigger operations on the particular third-party computing cloud based on events detected by the cloud agent in the third-party computing cloud corresponding to the cloud agent.

Abstract: Operations include determining billing for data being transmitted out of an Autonomous System (AS). An internal node in the AS determines billing for a packet transmitted out of the AS based at least on an egress path of the packet. The packet is received at the internal node in the AS via a particular overlay network of a plurality of overlay networks. Each overlay network may be associated with a corresponding tenant of a set of tenants. The internal node selects an egress path of the packet based on one or more characteristics of the packet. The egress path and the overlay network are mapped directly or indirectly to a billing counter. The billing counter is incremented based on (a) the transmission of the packet on the overlay network to the egress gateway and (b) transmission of the packet out of the AS on the selected egress path.
