SOA CIO Perspective

SOA --- CIO Perspective
2

• Gartner reports that "By 2008, SOA will be a
  prevailing software engineering practice, ending
  the 40-year domination of monolithic software
  architecture" and that "Through 2008, SOA and web
  services will be implemented together in more
  than 75 percent of new SOA or web services
  projects."

• A service-oriented architecture isn't a
  technology it's a way of doing business. It can
  even be a way of transforming your business.

4

• The potential of an SOA is in dramatically
  speeding up the application development process.
• It is a way to build applications and systems
  that are more adaptable, and in doing so, IT
  becomes more agile in responding to changing
  business needs

5

• At its simplest, an SOA turns application
  functionality into the software equivalent of
  Lego bricks. Take a piece of software (say, a
  customer-number verification tool), strap a
  well-defined interface onto it, and let other
  applications use the new "service" as needed.
  Create a library of such mix-and-match parts, and
  you can build composite applications to meet
  almost any business need, the same way Legos can
  morph from castle to crocodile to catapult when
  the same components are rearranged

• Example Restaurant
• Waiter
• Cook
• Manu card

• Reworking your IT framework as an SOA takes time,
  money, nerve and a strong business driver.
• Done for the right reasons, an SOA can save
  money on development costs (eventually) and
  increase your agility.

Example-- POC completed

• Use of Workflow system for approval.
• Real time interaction with SAP using a middle
  ware adaptors
• Generation of service requests for creation of a
  document and pull of information
• Applicability of the same architecture for
  information pull through mobiles
• Applicability to dealer vendor portals
• Applicability to third party manufacturers.

Example ??

• Intranet being developed for personalised web
  pages based on hierarchy.
• Link to KRA of the person
• Service requests to a database / cubes based on
  id
• Population of web page

Questions-

• Why should top management be involved in
  deploying SOA. It is arole of CIO.

• SOA is not a quick fix.
• SOA will only work if organizations lead with
  manageability. SOA by its very nature demands the
  aggregation of IP from many different sources.
  Scalability within SOA will come from
  managementnot development.
• SOA will only work if it is implemented within a
  business process context.

13

• SOA assumes that you will begin to write
  applications differentlyas a series of tightly
  defined services implemented in a loosely coupled
  manner.
• SOA dictates that change is the norm since this
  approach to software mimics the way a business
  operates and evolves.
