  • 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

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
