Voice over IP (VoIP) is an example of which type of cloud service?

Voice over IP (VoIP) is classified as Communication as a Service (CaaS) because it provides users with telecommunication services delivered over the internet. This model allows businesses and individuals to use voice communication and related services without the need for traditional telephone lines or on-premises hardware.

CaaS encompasses various communication-related features, including voice calls, video calls, messaging, and collaboration tools, all hosted in the cloud. By utilizing cloud technology, VoIP services can scale easily, reduce costs associated with traditional telephony, and offer a more flexible communication solution.

In contrast, IaaS (Infrastructure as a Service) refers to virtualized computing resources over the internet, PaaS (Platform as a Service) delivers environments where developers can build applications, and MaaS (Messaging as a Service) is specifically focused on messaging services rather than complete communication solutions.
