1. A host computing device comprising:
one or more containerized user-level applications configured for dynamic deployment by an orchestration engine;
a cloud native virtual router configured for deployment by the orchestration engine and operable in a user space of the host computing device; and
processing circuitry configured for execution of the one or more containerized user-level applications and the cloud native virtual router;
wherein the cloud native virtual router comprises:
a containerized routing protocol process configured for deployment as one or more containers and configured to operate as a control plane for the cloud native virtual router, and
a data plane for the cloud native virtual router, wherein the data plane is configured to operate an ethernet virtual private network (EVPN) encapsulation/decapsulation data path of an overlay network for communicating layer two (L2) network traffic of a containerized user-level application of the one or more containerized user-level applications, wherein the EVPN encapsulation/decapsulation data path comprises an integrated routing and bridging (IRB) interface providing bridging services for communicating the L2 network traffic of a bridge domain via a virtual routing and forwarding (VRF) structure.
