What is SOA

• Really

4
The Definition

• A service oriented architecture is an
  information technology approach for building
  applications that implement business processes
  (services) by using a set of loosely coupled
  black-box components orchestrated to deliver a
  well-defined level of service.

Lego blocks

• Interoperable
• Unbreakable
• Composable
• Reusable

What Technology is SOA Replacing?
Current IT System
Component Based IT

The Magical Black Box

• A Component or Device
• Inner workings are not understood
• Hides Complexity

If it aint broke, dont fix it

• Its all about reusing existing systems...

Web Service

• Common Interface Think Lego Bumps
• XML
• WSDL
• SOAP

11
Extensible Markup Language (XML)

• A human readable way of organizing documents on
  the internet

12
Web Services Description Language (WSDL)

• Describes all the commands and data required to
  use a Web Service
• Defines the Bumps

Simple Object Access Protocol (SOAP)

• A standard language that enables components to
  talk to each other

Why SOA
16
Why SOA?

• Do you want your business to?
• Respond quicker to marketplace
• Better align processes with business goals
• Make processes faster and more efficient
• Realize greater agility in your business
  practices
• Allow re-use of current systems

17
Why SOA?
SOA
A way to develop a flexible technical architecture
A way to streamline business processes
A way to become more agile

• Improved visibility within and across a process

• SOA services can deliver information faster and
  to more systems

• New value from existing investments

• Architecture components are less technically
  dependent

• Improved productivity

• Faster speed to market for future changes

• Increased customer satisfaction

• Easy integration of future systems

18
BPM SOA

• Improvement of the entire business process
  lifecycle, including modeling, management and
  optimization of processes
• Single dedicated interface that guides you
  through information and provides information in
  the appropriate format
• User empowerment balanced with corporate need for
  control and management

How to Implement SOA
20
5 Considerations

• Understanding the pain
• Defining the value
• Focusing on understanding
• Remembering the people
• Concentrating on the long term value

21
Roadmap

• Have you considered?
• Adoption and maturity models
• Where is the enterprise at in the relative scale
  of maturity in the adoption of SOA and Web
  Services?
• Assessments
• Does the company have pilots?
• Has the organization dabbled into Web services?
• How good is the current architecture?
• Should the organization keep going in the same
  direction?
• Will this scale to an enterprise SOA?
• Have you considered everything you need to
  consider?

22
Roadmap

• Have you considered?
• Strategy and planning activities
• How does the company plan to migrate to an SOA?
• What steps, tools, methods, technologies,
  standards and training need to be taken into
  account?
• Whats the roadmap/vision and how will the
  company get there? Whats the plan?
• Governance
• Should API or capability become a service? If
  not, which ones are eligible?
• Every service should bring value to the business.
  How will the company manage this process without
  getting in the way?
• Implementation of best-practices
• What are the best ways implement security,
  ensuring performance, complying with standards
  for interoperability and designing for change?

  to ensure quality and regulatory compliance. The
  company also adopted a more service-oriented
  approach, supported by the IBM Rational Software
  Development Platform, IBM Rational Unified
  Process methodology, and IBM Information
  Management products
• Benefits
• Passed numerous internal and external compliance
  audits without problem. Individual productivity
  and team efficiency have increased. They are
  better able to govern their development efforts
  and teams are better able to communicate
  resulting in less re-work, higher quality
  software, and faster time to market
