Considering an average of 10 to 18 domains per organization, with an average of 10-12 services per domain – we are looking at between 100 to 200 services as first class business services in an average organization end to end. If I map this to my current IT services portfolio of applications that are being served for my XPZ port operations, we support a total count of so called applications = 40. This number is going to increase to 150 services as we gradually go on adopting SOA. A lot of these services are from corporate shared services ownership as well.
