“Enterprise” vs. “Enterprise-wide”
Having discussed the notion of services as enterprise resources back in Chapter 4, it is important that there is a clear distinction between something that exists as a resource as part of an enterprise and something that is actually an enterprise-wide resource.
An enterprise resource is not a resource that is necessarily made available across the entire enterprise. Instead, it is a resource positioned for use within the enterprise, outside of and beyond any one particular application boundary. In other words, it is a “cross-silo” resource.
An enterprise-wide resource, on the other hand, is truly intended for use across all service inventories within an enterprise.
