Gartner defines communications platform as a service (CPaaS) as a cloud-based platform that enables businesses to embed a range of communications capabilities into applications over channels such as voice, SMS, email, messaging apps, and video. They also provide conversational capabilities, security, authentication, and automation. CPaaS delivers omnichannel, programmable experiences to enhance digital customer engagement. In 2026 and beyond, CPaaS aims to offer deeper capabilities, such as customer journey analytics, automation, personalization, and omnichannel engagement driven by AI and 5G. The purpose of CPaaS is to enable enterprises to enhance their communication workflows by providing simplified access to multiple communication capabilities without requiring the complex architectures typically needed to leverage these channels. CPaaS enables enterprises to shorten the time to market for new products and services, personalize communications, and orchestrate customer journeys across multiple channels. It delivers digital engagement and operationalizes customer experience, while also driving business efficiencies at scale with digital service delivery. It is modular/composable in design and can expand from initial single use cases to many others as additional business units learn of its value.
Gartner defines contact center as a service (CCaaS) as solutions offering SaaS-based applications that enable customer service departments to manage multichannel customer interactions holistically from both a customer-experience and employee-experience perspective. CCaaS is a key technology platform used to support the customer service experience, whether it be self-service or assisted by customer service representatives. All organizations need to offer customer assistance. The preference is for remote support via voice and digital channels over physical presence in offices and stores, though it is common for organizations to offer multiple options. The ambition is for customers to self-serve assistance, through web portals or chatbots. But it is also recognized that complex issues still need the support of employees. CCaaS technology is instrumental in orchestrating both self- and assisted-service engagement with customers. The technology can also manage the quality of engagement between the customer and the customer service representative, recognizing that premium customer experiences are achieved through premium employee experiences.
