What Is CPaaS? Understanding Communications Platform as a Service
This article is part of a larger series onVoIP.
CPaaS, which stands for communications platform as a service, is a cloud-based tool that allows businesses to add real-time communications features to existing business applications. These features include voice, messaging, email, fax, and video. With these customization capabilities, organizations offer a better user experience for customers and employees alike.
How CPaaS Works
A CPaaS platform provides a complete development framework, removing the need and hassle for businesses to build their own. In this ready-made environment, you’ll find software tools, pre-built applications, code samples, and application programming interfaces (APIs), which help customize communication features and channels.
The APIs, which are at the core of CPaaS models, are programming codes that facilitate data transmission between one software product to another viavoice-over- internet-protocol (VoIP)network. Think of them as mediators between apps, augmenting the communications capabilities of the application.
An example of API is SMS API, which allows an app to send messages such as alerts and autoresponders, marketing promotions, or appointment reminders to customers. Twilio, a CPaaS provider, offers two types of SMS APIs: programmable and conversations. Programmable SMS allows businesses to broadcast different kinds of messages to over 180 countries, while conversations API enables two-way engagement over SMS.
Benefits of CPaaS Solutions
Overall, a CPaaS solution improves how you communicate with customers and team members. Since communication is at the heart of business operations, this enabling technology benefits other aspects of the business, including cost and growth management. Here are the specific advantages of adopting CPaaS models:
The main benefit of adopting a CPaaS model is customization. Unlike aunified communicationstool, which integrates all capabilities in one platform—messaging, voice, chat, and video—CPaaS lets you cherry-pick features. Perhaps you need an SMS and chat feature on your app, but not voice and video. With CPaaS, you have greater control over which features to have on your business platform.
A CPaaS model lets you add more communication features as your business grows. With a development framework already available and comprehensive documentation to follow, it’s easy to build additional communication channels according to your needs. In the same way, you’re able to remove a feature you no longer use and quickly adapt to the changes happening in your business.
Given CPaaS solutions’ flexibility, businesses benefit from optimized costs—saving more money in the long run as you only pay for the communication features you need. Moreover, since these solutions come with APIs and software development kits (SDKs), you won’t have to build features from scratch and pay more for development.
The pricing model of most CPaaS providers contributes to optimized costs. Vendors like Vonage, for instance, use a pay-as-you-go pricing scheme, charging businesses only for the messages or calls sent or received. For thevirtual and toll-free number, it costs 0.60 cents to send a message and 0.55 cents to receive one.
A CPaaS solution makes real-time communication with customers possible. Your clients don’t have to go to your Contact Us page, fill out the form, and wait for a couple of days to receive answers to their queries. With in-app messaging or voice API, customers instantly connect with a company representative or agent. With frictionlesscustomer service, clients leave your platform satisfied and are more likely to do business with you.
Small businesses that store the personal information of customers and employees must be proactive in preventing data breaches. Fortunately, when you use CPaaS solutions, you benefit from the provider’s network security. Most vendors like RingCentral have end-to-end encryption (E2EE), third-party security certifications like ISO 27001, and user verification through two-factor authentication systems as security protocols.
CPaaS Features to Consider
The features provided in CPaaS solutions enable quick and straightforward development of communication capabilities. These are the common tools you’ll find in CPaaS products:
Communication APIs are the backbone of CPaaS systems, enabling different communication capabilities to be embedded into an app or website. These are some of the common APIs small businesses use:
- Voice API:This typically features calling capabilities you’ll find inbusiness phone systems. They include call routing, call forwarding, call recording, audio conferencing, call reporting,interactive voice response (IVR), and answering machine detection.
- SMS API:用于自动化营销信息、警报和雷竞技appnotifications, and autoresponders, this API typically features message queueing, long message concatenation, and character set support.
- Messaging API:This covers messaging on the web, social media, and apps. Maximize this to handle order or shipping updates and confirmations, product upselling, and customer polls and surveys.
- Verification API:This will be in the form of cross-channel two-factor authentication, account login attempt push notifications, or verification codes.
- Video API:Different providers will have different limits on the number of participants. For instance, RingCentral has a cap of 200 users for video meetings. The API enables access to meetings via browsers through webRTC technology. This removes the need for a downloaded app.
- Email API:Use this for sending automated messages such as account creation, shipping notifications, or password recovery. Maximize it for marketing emails such as monthly newsletters and product recommendations. Email APIs allow you to create custom triggers to send the right messages to your audience at the right time.
Most CPaaS providers have visual editors that help you build communication features such as SMS surveys, IVR, and call forwarding, even without technical expertise. These editors have drag-and-drop interfaces, making them easy to use for those with no coding background. A popular CPaaS provider, Vonage, has this kind of design studio that makes it easy to create IVR systems.
Most CPaaS solutions support common programming languages, namely:
- C++
- Go
- Java
- JavaScript
- Node
- .NET
- PHP
- Python
- Ruby
- Unity
To keep track of user interactions, CPaaS solutions provide access to historical and real-time reports. The platforms feature dashboards, where you see what’s happening in each communication channel.
The data presented in these dashboards are organized visually, in graphs, charts, or tables, for easy reference. They provide information that helps businesses evaluate key performance indicators (KPIs).
For instance, for voice API, the typical data points are the total number of calls, call duration, and disconnect reason. For messaging, you’ll find the total number of messages, the number of messages sent, and the number of messages received. Draw actionable steps in improving communications with these data points.
To measure service reliability, CPaaS providers offerservice level agreements (SLA)that commit to a certain minimum percentage of uptime. This is a critical consideration for small businesses, especially because you want to provide uninterrupted services for customers.
The gold standard for SLA uptime is 99.999% availability, which translates to just 78 seconds of downtime per quarter. The five nines can weather sudden surges prompted by different factors, including holidays or crises.
