A collocation center is where service providers keep servers of companies that need expert handling for their data. These third-party companies also provide web connectivity and technical support. They are a good option for companies who want to concentrate on their core product rather than the problems of IT infrastructure. This would also save time spent by the technical department of a company, thereby increasing productivity.

Outsourcing the job to a third party may seem wise, as the basic environment is suitable for such an activity. Broadly, this covers all aspects, including the building that would house the server. Typically, it should be placed near a glass fiber ring, with multiple fiber access points. The building should be guarded 24/7 by closed-circuit cameras. There should be relay tracks and cabinets that can help mount the servers. Cleanliness is a factor that is crucial for server set-up, to ensure favorable running conditions for computer hardware. Additionally, there should be a generator back-up in case of power failure.

There are some companies that engage the services of two different companies, one where the server is hosted and the other that provides Internet connectivity. Nearly all colocation centers offer a range of services to their customers, such as suites and racks for servers. Some providers offer services like a backup plan in the case of adversities, troubleshooting devices, bandwidth of the web connectivity and also assist in hardware replacement. Collocation facilities come at a price that differs from one service provider to another. Higher server configurations are more expensive. These companies also encourage the use of SLAs, or Service Level Agreements, that promise a wide range of services.
