“Colo” is short for colocation. In the context of data centers, colocation refers to the practice of housing privately-owned servers and networking equipment in a third-party data center. Instead of maintaining their own data center, companies can rent space in a colocation facility, which provides the necessary infrastructure, power, cooling, and physical security.

Relationship to Data Centers

  1. Infrastructure Provision: Colocation data centers provide the physical infrastructure needed to support the servers and networking equipment of multiple tenants. This includes robust power supply systems, cooling systems, and physical security measures.

  2. Shared Resources: By using a colocation facility, companies can benefit from shared resources such as high-speed internet connectivity, redundant power supplies, and advanced cooling solutions, which might be too expensive or complex to maintain independently.

  3. Scalability: Colocation allows businesses to scale their operations more flexibly. They can rent additional space and resources as their needs grow, without the significant upfront investment required to build and maintain their own data center.

  4. Physical Security: Colocation data centers typically have stringent physical security measures, including access controls, surveillance cameras, and on-site security personnel, ensuring that the colocated equipment is protected from physical threats.

  5. Network Connectivity: Colocation facilities often offer better network connectivity options, including multiple carrier options and direct access to major internet backbones, improving the performance and reliability of the hosted services.

Example: Equinix

Equinix is one of the largest colocation providers globally. Here’s how they use colocation:

  • Global Footprint: Equinix operates a vast network of data centers around the world, providing colocation services to companies of all sizes.
  • Interconnection Services: Equinix offers extensive interconnection services, allowing colocated customers to connect directly to cloud providers, networks, and other businesses within the same facility. This reduces latency and improves performance.
  • Reliability and Redundancy: Equinix data centers are designed with high reliability in mind, featuring redundant power supplies, advanced cooling systems, and robust security measures, ensuring continuous operation and protection of colocated equipment.

Benefits of Colocation

  1. Cost Savings: Companies save on the costs associated with building and maintaining their own data centers.
  2. Improved Performance: Access to high-speed connectivity and advanced infrastructure improves the performance of hosted applications and services.
  3. Scalability: Easy to scale up operations without significant capital expenditure.
  4. Focus on Core Business: Companies can focus on their core business activities while the colocation provider handles the infrastructure.


Colocation is a practical solution for businesses looking to leverage advanced data center infrastructure without the associated costs and complexities of maintaining their own facilities. By colocating their equipment in third-party data centers, companies can benefit from enhanced performance, scalability, and security.
