When you place a VoIP call or join a video meeting, the experience feels seamless—your voice and video just work. Behind the scenes, however, an invisible framework of computing models is orchestrating that experience, ensuring low latency, high reliability, and scalable performance.
Three of the most important concepts driving this evolution are cloud, edge, and fog computing. Each represents a distinct way of deploying compute power, and understanding their differences is key to building resilient VoIP and UC systems.
In this article, we demystify these models, explain how they shape the future of communications technologies, and show you where each one fits best in real-world deployments.
