Other ISPs have too narrow a vision, only selling a specific service. They may be overcome by broad new business trends that blindside them. Multiple backbone connectivity is important because it takes maximum advantage of the Internet's packet-switching flexibility. If one backbone fails, traffic can be rerouted over other backbones. This may slow response times for a given e-business B2B solution, but it will not halt business operations.
Architectural redundancy addresses the internal design of a partner's various data centers.
The better the design, the greater the redundancy and the more likely that serious component failure will go unnoticed by your e-business B2B application. Data centers within large corporations often include redundant switches and routers to keep business operational in case one switch fails. ISPs need to deploy the same strategy in regards to their own switches and routers. Of the data centers that I have reviewed, many had a primary source of power from a major electric company plus diesel generator backup, including a direct line to a diesel energy source. Physical security addresses the issue of deliberate or unintended compromise of business data.
