Who ranks for “data center interconnection”

Data center interconnect (DCI) is dedicated network connectivity that links two or more data centers together over short, medium, or long distances so they function as a single, unified environment.

Instead of routing traffic over the public internet, DCI uses high-speed packet-optical connections and private circuits to give organizations predictable performance, guaranteed bandwidth, and enhanced security.

Key Types of DCI Distances

Campus DCI: Connects multiple data centers within a close range, typically under 5 kilometers. Metro DCI: Links data center facilities and regional availability zones across a metropolitan area, usually within 100 kilometers. Long-Haul / Submarine DCI: Spans hundreds or thousands of kilometers across countries, regions, or oceans using high-capacity fiber optics.

Core Benefits and Uses

Disaster Recovery: Enables real-time data replication and automated failover so applications stay online if one facility fails. Workload Migration: Simplifies the live movement of virtual machines and balanced computing tasks between different physical locations. AI and Cloud Scaling: Connects massive distributed GPU clusters and multi-cloud environments to handle heavy data demands without bottlenecks.
