What is UCaaS and How Does it Work

Unified Communications as a Service or “UCaaS” is a form of communications service delivered over the cloud. With UCaaS, all of your communication solutions are hosted and managed elsewhere, so you can focus on maintaining consistent conversations, without the costly and time-consuming maintenance.

UCaaS platforms can include everything from enterprise messaging services to conferencing solutions, call recording, IVR, call management and much more. Many modern UCaaS solutions are also beginning to explore the possibility of adding collaboration features to their unified communication services.


UCaaS is a simple and effective solution that helps companies to access a range of useful hosted applications including instant messaging, video conferencing, file sharing and so on over the internet, without having to host the technology themselves.

As more companies migrate to a cloud communication platform, UCaaS provides a route to access the latest communication features, through a cost-effective pay-as-you-go solution. Already, UCaaS is expected to see a CAGR of over 23% up to the year 2022.


UCaaS is a cost-effective communication technology, capable of reducing the capex/opex associated with standard communications. Services are charged for on an annual or monthly basis according to how much you use. This means that you’re not paying extra for unnecessary features that your team doesn’t want or need.

UCaaS aligns employees by giving them access to the same communication platforms over the cloud. There are currently two UCaaS architectures available for businesses to choose from including -


Single-tenancy UCaaS: Single-Tenancy UCaaS involves the business receiving a custom-made software platform capable of integrating with existing on-premises applications. Single tenancy deployments are private, dependable and are often available to manage remotely

Multi-tenancy UCaaS: In a Multi-tenancy UCaaS environment, multiple companies or users share the same software platform. It’s like hosting your website on a shared hosting environment, where resources are divided between various locations
