CPaaS is changing the way we do business by making it quick and easy to develop services and then scale them quickly. In this blog post, we are going to define what characteristics define CPaaS and make a comparison between its providers and platforms which are offering top-notch communication services overcloud.
What is CPaaS?
A CPaaS (Communication Platform as a Service) is a cloud-based platform that allows organizations to add real-time communication features like voice, video, and messaging in their applications by deploying application program interfaces (APIs) without needing to build backend infrastructure and interfaces.
CPaaS offers a ready-to-use development environment in which anyone can create custom communication applications.
CPaaS is scalable and is provider-held and cloud-based so your business will save time and money on infrastructure to enable this feature.
