Abstract

Governing the design of services in an SOA including creating a high level service design from the service model; if the high level service design and the estimated cost of the SOA complies with predetermined service design verification policies, creating a low level service design from the high level service design; and if the low level service design and the estimated updated cost of the SOA complies with predetermined low-level service design verification policies, incorporating the low level service design in a design specification for the SOA.

Claims

1. A method of governing the design of services in a Service Oriented Architecture (‘

SOA’

), the method

receiving a service model, the service model having preliminary design patterns that include preliminary service components allocated to preliminary service layers of the SOA service architecture;

creating a high level service design from the service model;

estimating the cost of the SOA in dependence upon the high level service design;

determining, during an architectural inspection, whether the high level service design and the estimated cost of the SOA complies with predetermined high-level service design verification policies;

if the high level service design and the estimated cost of the SOA complies with predetermined service design verification policies, creating a low level service design from the high level service design;

estimating an updated cost of the SOA in dependence upon the low level service design;

determining, during a follow-up architectural inspection, whether the low level service design and the estimated updated cost of the SOA complies with predetermined low-level service design verification policies; and

if the low level service design and the estimated updated cost of the SOA complies with predetermined low-level service design verification policies, incorporating the low level service design in a design specification for the SOA.

2. The method of claim 1 further comprising communicating the design specification for the SOA to relevant stakeholders in the SOA.

3. The method of claim 1 further comprising creating a refined high level service design if the high level service design and the estimated cost of the SOA does not comply with predetermined service design verification policies.

4. The method of claim 1 further comprising creating a refined low level service design if the low level service design and the estimated updated cost of the SOA does not comply with the predetermined low-level service design verification policies.

5. The method of claim 1 wherein creating a high level service design from the service model further comprises:

defining an application service model for the SOA;

defining service application architecture for the SOA; and

defining a service technical architecture for the SOA.

6. The method of claim 4 wherein creating a low level service design from the high level service design further comprises:

refining the application service model for the SOA;

refining the service application architecture for the SOA; and

refining the service technical architecture for the SOA.

7. The method of claim 1 wherein the low level service design further comprises an operational model, a web services definition language service contract, a design interaction diagram, a design class diagram, and interface contract, a component model, and a documentation of the architectural decisions made for the SOA.

8. The method of claim 1 further comprising documenting the results of the architectural inspection and the follow-up architectural inspection.

9. The method of claim 1 further comprising capturing governance metrics describing the governance of the service design of the SOA.

10. A service for governing the design of services in a Service Oriented Architecture (‘

SOA’

), the service comprising;

creating a high level service design from a service model;

determining, during an architectural inspection, whether the high level service design and an estimated cost of the SOA complies with predetermined high-level service design verification policies;

if the high level service design and the estimated cost of the SOA complies with predetermined service design verification policies, creating a low level service design from the high level service design;

determining, during a follow-up architectural inspection, whether the low level service design and an estimated updated cost of the SOA complies with predetermined low-level service design verification policies; and

if the low level service design and the estimated updated cost of the SOA complies with predetermined low-level service design verification policies, incorporating the low level service design in a design specification for the SOA.

11. A system of governing the design of services in a Service Oriented Architecture (‘

SOA’

), the system comprising;

means for receiving a service model, the service model having preliminary design patterns that include preliminary service components allocated to preliminary service layers of the SOA service architecture;

means for creating a high level service design from the service model;

means for estimating the cost of the SOA in dependence upon the high level service design;

means for determining, during an architectural inspection, whether the high level service design and the estimated cost of the SOA complies with predetermined high-level service design verification policies;

if the high level service design and the estimated cost of the SOA complies with predetermined service design verification policies, means for creating a low level service design from the high level service design;

means for estimating an updated cost of the SOA in dependence upon the low level service design;

means for determining, during a follow-up architectural inspection, whether the low level service design and the estimated updated cost of the SOA complies with predetermined low-level service design verification policies; and

if the low level service design and the estimated updated cost of the SOA complies with predetermined low-level service design verification policies, means for incorporating the low level service design in a design specification for the SOA.

12. The system of claim 11 further comprising means for communicating the design specification for the SOA to relevant stakeholders in the SOA.

13. The system of claim 11 further comprising means for creating a refined high level service design if the high level service design and the estimated cost of the SOA does not comply with predetermined service design verification policies.

14. The system of claim 11 further comprising means for creating a refined low level service design if the low level service design and the estimated updated cost of the SOA does not comply with the predetermined low-level service design verification policies.

15. The system of claim 11 wherein means for creating a high level service design from the service model further comprises:

means for defining an application service model for the SOA;

means for defining service application architecture for the SOA; and

means for defining a service technical architecture for the SOA.

16. The system of claim 15 wherein means for creating a low level service design from the high level service design further comprises:

means for refining the application service model for the SOA;

means for refining the service application architecture for the SOA; and

means for refining the service technical architecture for the SOA.

17. The system of claim 11 wherein the low level service design further comprises an operational model, a web services definition language service contract, a design interaction diagram, a design class diagram, and interface contract, a component model, and a documentation of the architectural decisions made for the SOA.

18. The system of claim 11 further comprising means for documenting the results of the architectural inspection and the follow-up architectural inspection.

19. The system of claim 11 further comprising means for capturing governance metrics describing the governance of the service design of the SOA.
