Web Services Scales “Scales Up” on large “Scales In”systems on a machine “Scales Down” to devices Microsoft Confidential “Scales Away” spans organizations & “Scales geographies Out” by adding machines

Why Web Services Devices need to interoperate! Building devices that work with 3 rd party applications increases value to customer Build devices that work with Internet services could add revenue streams HTML and browsers are limited Browsers can’t automatically collect data Browsers can’t automatically control devices Custom protocols are costly Microsoft Confidential

Quality WS protocols will be long-lived They’re general purpose and are being adopted by many large companies Enterprise-ready framework Already proven in the enterprise Allow your devices to move seamlessly between So-Ho and enterprise environments Multi-party reviews and interop events for each spec Microsoft Confidential

Security Integrity, Confidentiality Channel-Based (TLS) Message-Based (WS-Security) Secure content Scenario – print job content securely over the wire, allowing devices to be implemented at secure sites Secure communications Scenario – secure check printing Microsoft Confidential

The Device Profile for Web Services Scaling WS to limited resource devices Microsoft Confidential
