3. 3 This paper details the key concepts in a 3-dimensional approach to creating dot-com system architecture.  SUNTONE ARCHITECTURE METHODOLOGY A 3-DIMENSIONAL APPROACH TO ARCHITECTURAL DESIGN The 3-Dimensional Framework that analyzes an architecture in terms of the three primary design dimensions:  Application Tiers,  Infrastructure Layers,  and Systemic Qualities. The process of developing an architecture through the application of “architectural patterns”. How QoS requirements should be used to drive the architecture definition process. How these principles are synthesized into the SunTone Architecture Methodology, which is iterative and incremental, architecture-centric, use-case-focused, systemic qualities-driven, and pattern-based.

4. 4 Sun's comprehensive approach for dot-comming the enterprise consists of the following primary components:  SunToneSM Architecture Methodology—a step-by-step process for creating dot-com architectures.  Our architecture reference model—a service driven architectural framework based on loosely coupled, asynchronous communication.  Architectural patterns—generic templates for structuring a system to meet rigorous system level requirements like scalability, securability, and manageability.  Solution sets—sample implementations of dot-com platforms such as e-tail, eCRM, eSCM, or Community Portals.  SI Partners—Consulting organizations certified to deliver the SunTone Architecture Methodology and particular solution sets.  ISV Partners—ISV products used to implement a solution set which are built with Java.2 Platform, Enterprise Edition (J2EE-technology) compliant products, or products with a well-defined roadmap for migrating to J2EE. The dot-com age is all about service delivery—anytime/anywhere access to any needed service with predictable availability, reliability, performance, and security. The SunTone Architecture Methodology focuses on how to identify, design, and deploy network services to deliver this quality of service, within the severe time constraints imposed by the dot-com space.

5. 5 The goal of the SunTone AM is to define and deliver network services that provide the desired functionality with a high level of predictability, so that these services can be counted on by end users or by other network services.

9. 9 The 3-Dimensional Framework, SunTone AM, and Patterns provide a clear, compelling approach that fills this need. It does not make dot-com architecture into a simple cookbook, but it does provide a frame of reference in which a talented, experienced architect can make the right decisions quickly and with confidence. SunTone AM helps you address these challenges by being:  Architecture-centeric  Extremely focused on systemic quality  Use case driven  Service driven  Pattern based  Risk mitigating  Iterative and incremental Design principle  Physically distributed  Logically tiered for separation of concerns  Service-based, not code-based  Assembled, not built  Implemented in layers  Consistently managed and controlled
