If you have ever joined a video meeting, sent a chat message, or placed a VoIP call, you have used UCaaS. A few letters stand for a simple solution — Unified Communications as a Service (UCaaS). The use of online communication and collaboration tools has seen a remarkable rise in the last two years, and now, there is no going back. UCaaS allows you to unify or integrate multiple collaboration tools into one solution, so that you have a single license to manage, and can oversee the entire infrastructure from one console. In other words, UCaaS can be defined as a cloud-based solution that enables calls, video conferencing, and chatbased communication. Since UCaaS is hosted in the cloud, it can be accessed from any device — whether it is an employee’s smartphone, a home computer, or a workstation in the office. No on-premises infrastructure is required, which means no upfront costs and easy deploy.
