Architecture

"No problem can be solved from the same consciousness that created it."

-- Einstein

To think about...

Save Our Architecture

“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

“...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)

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

How Much Will SOA Cost?

Cost of SOA = (Cost of Data Complexity +

Cost of Service Complexity + Cost of Process Complexity + Enabling Technology Solution)

Five SOA Myths:1.“SOA is easy”

2.“Once top executives are sold on SOA, your trouble are over”

3.“You can simply wrap legacy system with services”

4.“You can buy SOA out of the box”

5.“If You are using Web services, you’ve archieved SOA”
