This Amsterdam release of the requirements is targeted for those implementations that consist of Network Clouds: Vanilla OpenStack (based on Ocata [1]) and commercial Clouds for example: OpenStack (including Titanium - Mitaka from Wind River [2] and VIO - Ocata from VMware [3]) . Future versions of ONAP are envisioned to include other targeted cloud infrastructure implementations, for example, on-premise private cloud, public cloud, or hybrid cloud implementations, and related network backends, e.g. Azure et al.
