What is meant by "data center interconnection"?

Data center interconnection refers to the technology and methodologies that enable multiple data centers to connect and efficiently share data. This can involve a range of solutions including networking infrastructure, high-speed connections, and protocols that facilitate communication between distributed data centers. By establishing these connections, organizations can enhance redundancy, improve disaster recovery capabilities, and optimize data flows, allowing for more effective use of resources.

This definition underscores that interconnection is not merely physical proximity or sharing space, but rather an integral aspect of how data centers interact with one another technologically. It enables various operational benefits, such as load balancing, failover capabilities, and greater overall network resilience.

The other options do not capture the essence of data center interconnection. For instance, while sharing physical space may contribute to efficiency, it does not inherently involve the technological aspects of connection and communication required for true data center interconnection. Similarly, migrating data from one center to another is a logistical process rather than an ongoing connection between facilities. Finally, local networking systems may be relevant but lack the broader context of interconnectivity that spans multiple data center locations.
