Global facility services provider OCS has completed the first phase of a five-year IT infrastructure overhaul through outsourcing.

Employing over 65,000 people worldwide and headquartered in the UK, OCS' portfolio spans a broad range of services including engineering, security, catering and horticulture.

OCS is working with outsourcer eLINIA to maximise its back office performance. The first phase required the movement of IT infrastructure from the old OCS headquarters in Crawley to eLINIA's ‘green’ data centre in Slough.

The second phase entails the adoption of the OCS IT estate into managed services provided by eLINIA. eLINIA's green credentials were of particular importance in the selection process given the commitment of OCS to a sustainable environment.

Seventy percent of eLINIA's data centres around the UK are currently powered by renewable biomass energy sources, and eLINIA's Cardiff headquarters and network operations centre also rely entirely on energy from renewable sources.

Following a review of its internal IT infrastructure OCS took the opportunity to invest in IT infrastructure outsourcing when it moved into new headquarters in Tilgate, Crawley.

Brian Horsfield, group IT director at OCS, said: "As part of our move we recognised there was a need for us to outsource our key business application infrastructure in order to achieve greater scalability and support for our global business."

Data centre outsourcing in Europe is set to "surge", according to BroadGroup Consulting’s recent report on data centres in Western Europe. It said outsourcing currently only makes up 15 percent of the data centre market in Europe, "which leaves room for significant growth opportunities".
