Edge acceleration is a network architecture paradigm and a set of technologies that fundamentally involve distributing content, services, and application logic from distant central cloud servers to edge nodes located around the world. These edge nodes are typically situated at network exchange points of internet service providers (ISPs), in urban data centers, or at access points that are closer to users.<\/p>\n\n\n\n
