What is CPaaS (Communications Platform-as-a-Service)?

Share

Communications Platform as a Service (CPaaS) is crucial for expanding businesses that leverage cloud technologies and seek to tailor their communications framework.

But what is CPaaS, and how does it work? Contrary to virtual phone systems managed by VoIP providers, CPaaS capabilities demand coding from the ground up. This article will cover the CPaaS definition, architecture, features, and main benefits. Let’s begin.

What is CPaaS?

CPaaS is a cloud-based solution that empowers businesses to embed voice, video, and messaging functionalities directly into their applications. This eliminates the need for developing standalone communication systems, streamlining the integration of real-time interactions (RTC) within existing digital ecosystems.

An instance of this would be adding a support chat box to your website with the help of a CPaaS service provider.

As a subset of PaaS (Platform-as-a-Service), CPaaS is a great way for brands to select specific communication channels to add to their suite of business applications. Popular examples include texting, voice, and messaging apps.

As opposed to Unified Communications-as-a-Service (UCaaS), which delivers an all-in-one, ready-to-deploy suite encompassing phone service, video meetings, and call recording, CPaaS provides a customizable blank canvas.

With a comprehensive toolkit of communication APIs, businesses can tailor features such as telephony and messaging to fit seamlessly into their existing software.

CPaaS evolved from the days of early VoIP (Voice over Internet Protocol), launching in the 2010s with APIs for basic communications. As illustrated below, it quickly expanded to include video, AI, and omnichannel features, becoming highly customizable to suit companies of all sizes.

How does CPaaS work?

Five main components make up the architecture of a Communications Platform as a Service:

1. Cloud infrastructure

   This is the foundation of CPaaS, consisting of servers, storage, and networking resources hosted in the cloud. It provides the necessary computing power and connectivity to support various communication services.

2. CPaaS API

   APIs serve as the bridge between the cloud and the CPaaS integration. They allow developers to add communications services to a company’s business apps without additional backend infrastructure.

3. Application layer

   At this level, different types of applications utilize the CPaaS API to integrate communication capabilities. Common examples include mobile apps, web apps, or custom software.

4. Integrations via SDK

   Developers create integrations that offer communication capabilities through the CPaaS SDKs (software development kits). These enable better customer engagement, internal communication, or even automated notifications based on a specific flow.

5. Communication services

   Through CPaaS, business apps can sport a variety of communication services, including text messaging, voice calls, and video calls. Advanced features like chatbots or AI-driven customer service tools are also in the realm of possibility.

Simply put, CPaaS leverages cloud infrastructure via APIs, enabling developers with SDKs to integrate RTC services into applications. This architecture allows businesses to add communication functionalities to existing software.

Core features of CPaaS

There are many providers in the CPaaS market, each with its own product and capabilities. However, we can identify a few key features that pertain to this type of service. Here’s an overview.

Text messaging and apps

Messaging is the cornerstone of CPaaS. With it, businesses can send and receive text and multimedia messages or implement chats within their apps and websites.

This is beneficial in many scenarios, ranging from marketing campaigns to customer support interactions. Texts and chats can even be used for security procedures, such as two-factor authentication.

CPaaS platforms are evolving to incorporate 10DLC services designed to comply with new carrier regulations and standards in the United States. This alignment ensures businesses can send A2P messages with confidence, knowing they adhere to regulatory requirements and avoid penalties or filtering.

Voice and video communications

Voice and video communications, enhanced by the integration of call masking and cloud telephony, represent key features offered by CPaaS providers.

These providers enable the seamless incorporation of voice and video capabilities into business apps or websites. This includes everything from simple voice calls to comprehensive video conferencing features.

Thus, companies can easily entertain direct contact lines with customers regardless of their location. Communication among team members also benefits from this feature.

RTC powered by WebRTC

The real-time communication capabilities of CPaaS are powered by WebRTC technology. It allows web pages and mobile apps to support peer-to-peer communication directly through mutual file sharing, thus eliminating the need to install plugins or other native software.

This enables users to engage in live audio and video chats directly from their web browsers or mobile apps.

On-demand SIP trunking

Some CPaaS providers offer on-demand Session Initiation Protocol (SIP) trunking. This feature allows businesses to replace traditional phone lines with internet-based voice communications.

With SIP trunking, companies can scale their voice communications flexibly, connect with global telephony networks, and integrate voice services.

Integration via APIs

The true power of CPaaS lies in APIs, which allow for the seamless integration of communication features into existing business systems. They enable developers to customize and automate communications based on specific business needs and workflows.

CPaaS API integration ensures businesses can enhance their applications with communication features without disrupting their operations.
