Co-location
Co-location is placing communicating or interdependent systems and services in the same or nearby physical location to reduce communication latency or overhead.
Latency
Colocation is the placement of communicating systems or services in the same physical facility or nearby location to reduce communication distance.
- How it is used
- Uses component placement to reduce data-access and communication latency across distributed and multicore systems.
- How deep it goes
- Explains internode and intranode placement choices and physical latency constraints, without specifying a deployment procedure in the supplied evidence.
- Examples
- Compares remote and same-data-center databases, and cites an REST API with embedded SQLite and exchange-adjacent trading servers.
- What you can do after
- Evaluate/understand where moving communicating services or colocating compute and memory may reduce latency, while recognizing last-mile limits.

Colocation is a service in which an organization houses its computing infrastructure in rented space within a third-party data center.
- How it is used
- Positions colocation as a traditional infrastructure option between on-premises deployment and cloud computing.
- How deep it goes
- Defines ownership, facility responsibilities, and customer interconnection but stops short of configuration or operational procedures.
- Examples
- Illustrates two customers housing servers in one data center and connecting their networks for resource sharing.
- What you can do after
- Evaluate whether rented data-center space fits an organization retaining responsibility for its servers and operations.
