What Is CPaaS? Pros, Cons, Features, Top Providers and More

The demand for CPaaS solutions is increasing at a rate of 40% every year. As consumers’ reliance on their mobile devices increases, marketers are learning that it’s critical to include a communications approach and solution that allows them to connect with customers wherever they are. By 2025, there will be over 75 billion connected devices as more enterprises leverage CPaaS to create more robust business models with IoT.

The coronavirus pandemic has been a significant driver of CPaaS market expansion. In 2020, many traditional businesses awoke to the fact that establishing a mobile connection with customers was no longer something they could defer. Large global firms were suddenly confronted with the difficulty of drastically altering their customer interaction model, which involved more than simply a mobile app and support phone number.

CPaaS solutions offered a method to adapt quickly while still providing high-quality services without disrupting their operations. Today, there’s every indication that the CPaaS market will continue its steady growth well into the near future. 

But What Is CPaaS?

So, what does CPaaS mean and what does CPaaS stand for? CPaaS stands for “communications platform as a service.” CPaaS providers like Signalmash, Twilio and Plivo offer features such as messaging, enterprise chat, text notifications, and voice call automation to their customers. Companies that offer CPaaS solutions either provide a communications API or access points like webhooks or SDK. This means if your company has an app or platform and needs texting and voice capabilities, you simply use an API of the CPaaS provider and those features can be incorporated into your app or platform. In other words, you don’t need to build your own communications platform and infrastructure. You rely on the CPaaS to do that for you. This saves you a lot of time and money.

CPaaS is also referred to as ‘messaging as a service.’ It is deployed on cloud servers and is accessed by app developers through an API (typically REST). Businesses leverage CPaaS to build more complex communication solutions that involve multiple channels like messaging, voice, and video conferencing.

CPaaS providers also offer more intelligent communication tools like message bots, chatbots, 2-factor authentication, SMS marketing campaigns, automotive telematics, machine traffic monitoring, smart home services, etc.  A CPaaS API can easily be integrated into a SaaS, generally by developers with programming expertise. 

The Building Blocks of CPaaS

CPaaS is based on three fundamental building blocks:

  1. It provides a stable, scalable, agile, and multi-channel environment for businesses to enhance customer engagement across the digital space.
  2. It enables you to focus on your business and be flexible with your technology stack. CPaaS allows you to use any programming language or framework that supports an API (REST or otherwise). 
  3. It provides ready-made integrations for common services like push notifications, data storage, user management, etc. This allows developers to concentrate on feature development rather than spending time managing backend infrastructure. It also reduces the cost of maintenance and allows developers to build CPaaS in a scalable way.

What CPaaS Does for Businesses

CPaaS has become a vital tool in the arsenal of every business that wants its app or platform to interact with end-users via different digital channels. It offers the foundation to create all types of functionality from productivity tools to interactive, integrated experiences like smart assistants and customer support bots.

CPaaS solutions allow you to add one or more features within minutes using universal programming languages (API), which make it easy to connect an app with the existing infrastructure. This transition is perfect for enterprises that want their transition into product development platforms as painless as possible.

The Advantages of CPaaS

CPaaS has some notable advantages, including:

— CPaaS customers use an API to quickly integrate their own app with CPaaS solutions. An API is the most efficient way to build scalable, reliable apps that meet customer requirements for responsive services.

— CPaaS providers offer easy access to backend infrastructure, allowing developers to create new user experiences and interactions on different digital channels.

— CPaaS offers serverless computing, freeing developers from managing servers and ensuring app up-time. This is especially useful for businesses whose operations run 24/7 or those where instant messaging is critical; CPaaS can automatically scale up or down according to demand. This also allows them to save costs. 

— CPaaS enables developers to create new types of apps with voice and texting capabilities without building backend infrastructure. This is especially useful for small businesses that cannot afford to hire programmers and large companies that can reduce costs by working with CPaaS instead of hiring full-time engineers to develop their own omni-channel solutions.

— CPaaS provides built-in user management tools so users can easily see statistics and track the performance of the CPaaS features.
