Based in the cloud, CPaaS (Communications Platform as a Service) allows developers to add communications capabilities to existing applications and enterprise systems without needing to build either the network infrastructure or the supporting interfaces. These platforms typically include standards-based APIs (Application Programming Interfaces), sample code, SDKs (Software Development Kits), webhooks and libraries to help developers quickly build the applications.
CPaaS is sold commercially in the same way as SaaS. Enterprises typically have very low up-front costs, pay only for what they consume and can cancel at any time. The cost of both the infrastructure and the communications tools utilized are combined in an easy to manage per message or per minute pricing model.
This means that enterprises no longer have to use separate, dedicated hardware or third party software applications for internal or external communications. They can now offer voice, video and messaging in their own apps, business support systems or call centre solution which connects to the platform via an API. This, in turn, means that communication tools become much more flexible, scalable, and affordable, resulting in more experimentation, less fear of vendor lock-in and ultimately, a faster time to market for new ways to engage their customer bases.
