  • Component Packaged well defined set of functionality that has a well defined inputs and a well defined outputs. Service vs component Business heavily influences the definition of the service It provides a tangible business value
  • SOA governance Why Why are we building this Service Why are we doing it this way How How are we going to build it (Process) How are we going to build it (architecture & Design) How are we going to pay for it. How are we going to support it. When When we will build it When we will deploy it When we will revision it Who Who will build it Who will support it Who will pay for it Who will be effected by the change Who is the owner / sponsor, stakeholders. What What are we building What are we using to build it What is the business value

    2. 2. <ul><li>Challenge </li></ul><ul><ul><li>Currently oversees and directs the preparation of the Master Plan for the State of Qatar. The Master Plan for Qatar is a comprehensive long term master plan that will guide the physical development of Qatar through the year 2025 </li></ul></ul><ul><ul><li>The country has witnessed  big construction development in all fields, and re-planning of many areas in Doha. As a result, and because of the intense construction activities, there is delay in processing of development and building permits. </li></ul></ul><ul><li>Working Smarter </li></ul><ul><ul><li>The government, therefore,  considered it necessary to establish a complex for issuance of  building permits in which all departments and authorities related to issuance of building permits shall be represented. </li></ul></ul><ul><ul><li>Simplification of procedures for obtaining various building permits, in coordination with the concerned services authorities, establishments and departments. Preparation of periodic reports on building permits Applications, and to  provide these reports to the concerned authorities. </li></ul></ul>
    3. 3. <ul><li>Service-oriented architecture is a client/server software design approach in which an application consists of software services and software service consumers (also known as clients or service requesters). SOA differs from the more general client/server model in its definitive emphasis on loose coupling between software components, and in its use of separately standing interfaces. </li></ul>
    4. 4. <ul><li>A Service-Oriented Architecture is an enterprise-scale IT architecture for linking resources on demand . These resources are represented as business-aligned services which can participate and be composed in a value-net, enterprise, or line of business to fulfill business needs. The primary structuring element for SOA applications is a service as opposed to subsystems, systems, or components. </li></ul>
    5. 5. <ul><li>An IT architectural paradigm for building Business services that are loosely coupled and can be connected on Demand. </li></ul>
    6. 6. <ul><li>It is an IT Architecture, and a paradigm. </li></ul><ul><li>It is about loosely coupled services. </li></ul><ul><li>Integrated on Demand. </li></ul><ul><li>It is all about Business Services. </li></ul><ul><ul><li>Not web services. WS is implementation technology. </li></ul></ul><ul><ul><li>The business helps you define it </li></ul></ul><ul><ul><li>It provides tangible value. </li></ul></ul>
    7. 7. <ul><li>Tech (Bottom Up) </li></ul><ul><li>Business (Top Down) </li></ul>
    8. 8. <ul><li>It is not just another IT architecture. (like 3 tier, client/server, etc). </li></ul><ul><li>Always focus on the tangible business value. </li></ul><ul><li>Make a clear distinction between services & components. Why? </li></ul><ul><ul><li>Chatty architecture. </li></ul></ul><ul><ul><li>Very flat architecture. </li></ul></ul><ul><ul><li>No tangible Business Value. </li></ul></ul>
