Synonyms: UCaaS
Unified communications as a service (UCaaS) is a category of “as a service” or “cloud” delivery mechanisms for enterprise communications. Similar to platform as a service (PaaS, where data center capacity is made available to an enterprise on a consumption model from a service provider), with UCaaS, unified communications services can be made available from the cloud to businesses from SMB to enterprise.
UCaaS is part of a global industry trend towards cloud services, also known as digital transformation.
