  4. 4. Enterprise  Architecture  &  Cloud   Definitions ●  System Architecture The fundamental organization of a system embodied in its components, their relationships to each other and to the environment, and the principles guiding its design and evolution. (IEEE 1471-2000) ●  Solution Architecture It is an overall Technical Architecture that can be reflecting different elements of technology within the enterprise. Its scope can be data, software, application or any IT Infrastructure technical components ●  Architecture Framework A resource that guides the development or description of an architecture ●  Business Architecture A perspective of the overall architecture reflecting enterprise mission, strategies, goals, business drivers, business processes, information flows, and the supporting organizational structure ●  Enterprise Architecture A blueprint (set of models) that depicts how various business and technical elements work together as a whole Elabora=on   Abstrac=on  11/10/11 Sherif AbdElGawad 4
  5. 5. Enterprise  Architecture  &  Cloud   Architecture Vs. Design Example: System Architecture & System Design !  Design: How each component should be built !  Many different designs may address the same need !  Different Architectures imply different needs !  Analogy: !   House: !   Architecture:Number of rooms, main structure, character, guiding lines. !   Design: Interior Design, rooms structure, electricity, ..etc.11/10/11 Sherif AbdElGawad 5

  8. 8. Enterprise  Architecture  &  Cloud   Enterprise Challenges The Need of Enterprise Architecture ●  System Complexity: Organizations were spending more and more money building IT systems ●  Poor Business Alignment: Organizations were finding it more and more difficult to keep those increasingly expensive IT systems aligned with business need. ●  Organizations Grew Organically, some Enterprises had a well defined Architecture, some just emerged/just happened! Some  are     Designed   Some  just   happened  11/10/11 Sherif AbdElGawad 8
  9. 9. Enterprise  Architecture  &  Cloud   The Enterprise Architecture (EA) Making Sense Of Organization Messes ●  EA is a way of understanding and managing complex behaviors of different Enterprise Systems Interactions. ●  EA Connects Strategy and Goals to Execution ●  EA provides a common basis for understanding and communicating how systems are structured to meet strategic objectives ●  EA enables flexibility and adaptability, so that business capabilities can keep pace with changes in strategy.11/10/11 Sherif AbdElGawad 9

Enterprise  Architecture  &  Cloud   The Open Group Architectural Framework TOGAF s View Of Enterprise Architecture ●  TOGAF describes itself as a “Framework” ●  The most important part of TOGAF is the Architecture Development Method (ADM).

A collection of Technology Roadmap presentations and Reference Architecture documents provide guidance and a high level strategy for these core technology investments.11/10/11 Sherif AbdElGawad 12
