© 2006 Progress Software Corporation3 A Little About Sonic  We’re all about Integration Message-centric (async) Highly distributed Legacy / Mainframe Data adaptation Orchestration  “Connect everything… achieve anything”

© 2006 Progress Software Corporation4 Different Strokes  We live in a multi-protocol world JMS, FTP, UDP, Jabber, etc.  Not always necessary to switch… Services rarely move from one to another  …but necessary to adapt! You never know who you might be talking to Data formats, protocols, semantics

Newly shared security domains, registries, etc  Shared models can really help here WSDL, Bindings

© 2006 Progress Software Corporation6 The Promise  Web Services as common “glue” for talking to a variety of platforms  Wire-level interoperability to avoid the “many adapters” issue  A composible set of specs which smoothly take you from simple to richly-featured  Distributed extensibility and evolution  Interop… also WRT Skills and Tools

© 2006 Progress Software Corporation7 The Reality  Lack of community architectural consistency No standard for how to write/use extensions No real framework for bindings with various capabilities  Interoperability problems Whither Soapbuilders/WS-I?  Perception as bloated, vendor-controlled  …and some great successes too

Metadata about resources is critical –Content-type is NOT enough …but you shouldn’t require EPRs to get it  Single URI -> single resource Need stronger curb on use of RefPs Policy, Sem Web assertions, etc.  Benefits of URIs are well-understood, let’s not throw them out

© 2006 Progress Software Corporation9 Bindings  We love bindings! Design a service in the abstract (types, operations) Bind to particular formats, policies, addresses  Great for managing change Evolution Apply policies

© 2006 Progress Software Corporation10 A Common View : Benefits  You get a lot from a common service model Manageability / governance Registries Interoperability Tooling (codegen, orchestration) Composibility (intermediaries/mediation)  Is WSDL it?

© 2006 Progress Software Corporation11 We’re Not Highlanders  “There can be only one” – NOT!  There is a place for WS next to the Web  Can we get to a place where enterprise “ility-enabled” apps, over a variety of underlying protocols, gain from what we’ve learned from the Web? URIs, Proxies, Uniform IF

© 2006 Progress Software Corporation12 So Where Do We Go From Here?  Collect “enterprisey” use cases Build taxonomy and best practices Demonstrate the same story with WS and REST? Picking the right tool for the right job  Push harder for architectural coherence EPRs/URIs – please let’s get the word out Is “composibility” a myth? Versioning  Interop work?
