…for those having internal debates about datacenter build/buy, here’s another argument for “buy:” Global Data Center Services Provider CyrusOne Says Customers to Benefit from Carrollton, Texas, Data Center Tax Incentives | CyrusOne.
When looking at datacenters in a global economy, it would be wise for the lead technologist in enterprises to consider potential external DC advantages (e.g. N+1 power grids, green power, generator capacity, etc.) along with anticipated cost advantages.
Finally, on a national or even global scale, unless an enterprise has multiple datacenters distributed to minimize network latency concerns, how can a “build” strategy compete with what Equinix has done with their Internet Exchange ( http://www.equinix.com/solutions/by-services/interconnection/exchanges/equinix-internet-exchange/ ) or what CyrusOne is doing something in a similar vein with their CyrusOne National IX ( http://www.cyrusone.com/cyrusone-national-ix-internet-exchange.php )?
As a broad generalization, a “TBM-centric CIO” would be wise to begin planning how to migrate out of their DCs now, even if it means establishing an initial contract with a colo company and implement new systems, or DR/BCP systems, as the need arises.
