• 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.

• 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 architecture

s. Our architecture reference model—a service driven architectural framework based on loosely cou

pled, asynchronous communication. Architectural patterns—generic templates for structuring a system to meet rigorous system level r

equirements like scalability, securability, and manageability. Solution sets—sample implementations of dot-com platforms such as e-tail, eCRM, eSCM, or Co

mmunity 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.

• 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.

• 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
