Having your Unified Communications system running “in the cloud” (often referred to as UCaaS – Unified Communications as a Service), simplifies the management, security and flexibility of the platform.  It is the method of choice if you have a diversified workforce, including office-based, front-line, traveling or on-the-road and remote workers, as having your UC hosted on-premise requires the use of a VPN (virtual private network) for remote or off-site workers to access your system.  This can result in network bottlenecks, and latency issues.  In addition, deploying a UCaaS platform to your organisation often results in significant cost benefits, due to having all tools and applications, security, maintenance, and management bundled in the one subscription.
