A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and various security devices.

Organisations can host their own data centre but can outsource by either co-location or hosting within purpose built facilities as the costs of building and managing your own a data centre are very high.

The simplest Data Centre is a Tier 1 data centre or basically a server room. The highest level is a Tier 4 data centre, which is designed to host mission critical computer systems, with fully redundant systems, fire protection and security controlled by biometric access control.

This has seen significant growth in the evolution of providers in the Australian market. Some which specifically target Government & Enterprise clients through to scalable solutions for SME’s.
