2. SOA Service-oriented Architecture

5. “ SOA is a form of technology architecture that address to the principles of service-orientation . When realized through the Web services technology platform, SOA establishes the potential to support and promote these principles throughout the business process and automation domains of na enterprise” (Thomas Erl, “SOA Concepts, Tecnology and Design”, pg.54) SOA Definition

6. “ ...This will shift the massive software industry mainstream into the new software-engineering reality: By 2008, SOA will be a prevailing software engineering practice, ending the 40-year domination of monolithic software architecture .” (Gartner Group, April’03) Gartner and SOA

11. Timeline “New Architecture” Project Nov’05 - First meetings with SOA product vendors Mar’06 – New Architecture proposal (draft) ready Jun’06 – POC (Proof Of Concept) have been completed Feb’06 – SOA vendors have been chose Oct’06 – Comercial proposal revisited and adjusted Mar’07 – Start deployment “New Architecture” Phase I

20. How Much Will SOA Cost? Cost of Data Complexity = (((Number of Data Elements) * Complexity of the Data Storage Technology) * Labor Units)) Number of Data Elements being the number of semantics you're tracking in your domain, new or derived. Complexity of the Data Storage Technology, expressed as a percentage between 0 and 1 (0% to 100%). For instance, Relational is a .3, Object-Oriented is a .6, and ISAM is a .8. So, at $100 a labor unit, or the amount of money it takes to understand and refine one data element, we could have: Cost of Data Complexity = (((3,000) * .5) * $100) Or, Cost of Data Complexity = $150,000 USD Or, the amount of money needed to both understand and refine the data so it fits into your SOA, which is a small part of the overall project by the way. If you get this, you can get the rest of the cost analysis procedure; just reapply the same notions to: -Cost of Service Complexity -Cost of Process Complexity -Enabling Technology Solution

21. How Much Will SOA Cost? Cost of SOA = (Cost of Data Complexity + Cost of Service Complexity + Cost of Process Complexity + Enabling Technology Solution) http://weblog.infoworld.com/realworldsoa/archives/2006/11/how_much_will_y.html#more
