Web Services in DoD Environments
• Service OrientaGon plays a big role DoD “SOA is so strategic, in fact, that SOA underlies how the DoD expects
to achieve its mission in the 21st century” ZapThink
• DoD is an organizaGon of outstanding complexity
• Mission CriGcal Services

Web Services in DoD Environments

Net Centric Warfare
• Robust network for: improved informaGon sharing, and shared situaGonal awareness
• InformaGon as Strategic Military Asset – The right informaGon, at the place, at the right Gme
• Goal is to achieve Agile InformaGon • Represents a fundamental shiT in military culture, away from powerful compartmentalized war machines and toward interconnected units operaGng cohesively

Global Informa<on Grid
• InformaGon as Strategic Military Asset – InformaGon is needed at the right Gme

WSDL and SOAP
WSDL and SOAP were never designed to model complex interacGons. The limitaGons include no standard ways to:
• Define a "unit of work" spanning mulGple operaGon invocaGons (begin / end)
• Specify the sequence in which operaGon needs to be invoked
• Correlate operaGons invocaGons as part of a unit of work
• Specify the intent of a SOAP message

WS-‐Addressing
Endpoint Reference • Provides for Dynamic Endpoints
![Page 13: Importance of WS-Addressing and WS-Reliability in DoD Enterprises](https://reader034.vdocument.in/reader034/viewer/2022051207/544615eaafaf9feb2a8b477d/html5/thumbnails/13.jpg)
WS-‐Addressing
• Provides transport neutrality – IdenGty Web Service Endpoints – Secure End-‐to-‐End endpoint idenGficaGon in messages
• Support message transmission through processing nodes such as: – endpoint managers – Firewalls – gateways

DoD’s Need for WS Accuracy
• Cyber Warfare – informaGon-‐centric guerrilla tacGcs
• Security • Predictability
