UCaaS Out-Weighing On-Premises UC
Unified Communications as-a-Service (UCaaS) capabilities now exceed those available from premises-based UC solutions, according to Gartner's 2017 Magic Quadrant for worldwide UCaaS.
The pace of UCaaS innovation is accelerating as vendors focus R&D resources and innovation on cloud delivery. Gartner said businesses are evaluating a fragmented UCaaS landscape to ensure that the provider matches their requirements. Although on-premises UC still accounts for roughly 70 percent of the offerings sold to midsize to large enterprise, UCaaS providers are expanding their capabilities to meet enterprise service needs.
The two architectures deployed in the UCaaS market is multitenant, in which customers share a common software instance; and multi-instance, where each customer receives its own software.
