It is very important to establish why both vendor and end-user communities within the IT industry are going through the trouble of adopting the service-oriented computing platform and embracing all of the change that comes with it.
The vision behind service-oriented computing is extremely ambitious and therefore also very attractive to any organization interested in truly improving the effectiveness of its IT enterprise. A set of common goals and benefits has emerged to form this vision. These establish a target state for an enterprise that successfully adopts service-orientation.
The upcoming set of sections describe each of these strategic SOA goals and benefits (also displayed in Figure 3.26):
Figure 3.26 The seven identified goals are inter-related and can be further categorized into two groups: strategic goals and resulting benefits. Increased organization agility, increased ROI, and reduced IT burden are concrete benefits resulting from the attainment of the remaining four goals.
- Increased Intrinsic Interoperability
- Increased Federation
- Increased Vendor Diversification Options
- Increased Business and Technology Domain Alignment
- Increased ROI
- Increased Organizational Agility
- Reduced IT Burden
It is beneficial to understand the significance of these goals and benefits prior to studying and applying service-orientation so that design principles are consistently viewed within a strategic context.
An important message of this book in general is that there is a concrete link between successfully applying service-orientation design principles and successfully attaining these specific goals and benefits (a point which is further detailed in Chapter 16).
