Some of the great business opportunities for Unified Communications as a Service (UCaaS) integrators and Value-Added Resellers (VARs) have been the emergence of cloud, telephony and Unified Communications (UC) technologies such as VoIP and virtual data center compute / storage. Others include the adoption of cloud operating systems such as OpenStack, enabling hyper scale-out of infrastructure. The cloud is enabling these services through its reduced cost and plentiful bandwidth of the public / private infrastructure.
