“The Power of an SOA Demo?” An Open Dialogue
In the spirit of the social learning . . . • In the spirit of the social learning true of a community of practice, an open dialogue to get beyond the rhetoric
Dig into the aspects of SOA . . . • Dig into the following aspects of SOA and what a public “demo” could offer agencies within the federal government: • Interests • Desires • Challenges
Context • SOA is Analogous to Splitting an Atom - The concept is remarkably simple, yet how to go about doing so and the consequences of having done so, are exceedingly complex. • A number of new issues • Governance, Granularity of Service, Semantic Parity, Quality of Service, Service Level Agreements, etc . . . • A mountain of rhetoric • ESB, EDA, BPM, BAM, etc . . . • A sea of standards • Some overlapping, some conflicting, some missing • A universe of new products • Some free, others expensive, and many complicated . . . All with some level of proprietary lock-in hidden behind a façade of standard compliance
Where to start . . ? • Who are you? • Name • Role • Agency • What is your interest? • Technical • ROI • Other?
What is the interest . . . ? • What would you want to see as . . ? • A CFO? • A CIO? • An Enterprise Architect? • A Technical Architect? • A Business Stakeholder?
What is the reference point . . ? • What background experience can be assumed? • What concepts are known? • What vocabulary is common? • How do you start the conversation?
Putting it in Context • To understand SOA it is important to not only define it, but to put it in context. There are several pertinent contexts to be considered: • Values, Qualities, and Practices – What are the benefits which merit its pursuit? What are the qualities that define it? And how are they achieved? • On going evolution of IT – How and why it has come to pass? • Key enablers – How has it become widely available? • Drivers – Why now and what will be directing its future progression? • Generations – What is its likely path of progression? • Implications – What are the likely consequences?
How could a demo contend with? • The challenges of getting support for SOA? • Demonstrating the value and the potential of something non-visual? • Illustrating key concepts? • . . ?
Other Dimensions . . . ? • Practices, Qualities, and Impediments of SOA • Fundamental Practices • Qualities of SOA • Best Practices of SOA • Impediments to SOA • Practices arising from and necessitated by SOA • Reference Model • Common Misconceptions
Successful . . ? • Take the conversation offline and extended
Significance of History . . ? • An examination of integration for what it is: • What if integration were not an after thought of systems development? • What if systems were architected for integration? • What if integration was not a one time effort, limited by the functionality and data it dealt with, but accepted as an on going and continual process? • What if integration was not a technical challenge requiring specialized skill but rather a fundamental competency of an enterprise and intuitive to non-technical resources? • What if integration was not a technological or business impedance, but rather a fundamental enterprise capability and readily accessible to wide audience? • Leads to a reexamination of a system for what it is: • What if the enterprise were comprised of discrete units of readily accessible functionality instead of separate systems? • What if application development were merely connecting and orchestrating those units of functionality? • What if the enterprise was the system and integration was a common practice?
