Building an SOA without the hype
And anyone without an SOA strategy may as well give up and go home, because everyone else has got one.
The thing is, SOA is not a new concept. IT started out as a service to business; network providers offer a service to connect computers together; the chargeback scheme some IT directors use to charge business departments for IT; and the whole concept of utility-based computing relies on the premise of a service oriented approach to IT. Moreover, operating systems, databases and infrastructure middleware provide software architecture which deliver services that applications can use. Sounds very much like an SOA.
