Overview
Effective management of system capability is crucial for business success and sustenance of competitive advantage. System Architecture needs to maintain a balance across multiple factors, viz., rapidly evolving technology, dynamic business scenarios, and integration with diverse systems, without increasing either the cost of software development or the complexity of software systems.
Service-oriented architecture (SOA) offers a framework for building and integrating software components as reusable services, promoting flexibility, scalability, and reusability across different applications and platforms. When working with IT architecture consulting, the principles and best practices of service-oriented architecture should be considered to align the resulting system architecture with an organization's long-term goals and objectives.
Enterprise System Architecture needs to be expressed effectively for addressing key business concerns such as:
- Modernizing hardware and software environments to simplify IT infrastructure.
- Achieving quality attribute objectives for applications, encompassing availability, scalability, performance, reliability, portability, and maintainability.
- Addressing security challenges related to integrating numerous applications, devices, and data sources.
The practice of systematic development can provide benefits in terms of quality and cost gains by adherence to architectural guidelines. A key premise of this logic is that important decisions may be made early in system development in a manner similar to the development of civil architecture projects.
Our Approach
Cybage recommends an approach based on the generally accepted practices for architectural description and provides a technical framework for further evolution in software architecture consulting. Our criteria-based selection approach describes how the system or product will be constructed, the critical components, and their applicability from a high-level, logical perspective.
Mapping such a selection against the available templates helps to leverage architecture principles for defining the system architecture, which addresses the visibility, changeability, and collaborative aspects to meet the defined quality expectations of the customers.
What We Do
The initial phase involves a thorough analysis of system and product scenarios, encompassing various aspects such as domain knowledge, industry practices, and statistical data. Additionally, an evaluation of tools and technology usage is conducted to ensure alignment with project requirements. Factors like costs and timelines are scrutinized to establish realistic project parameters. Moreover, insights gleaned from similar systems are leveraged to inform decision-making and refine strategies for optimal outcomes.
During the identification phase, key parameters are meticulously outlined to guide the architectural process effectively. This includes determining the architectural principles applicable to the project's scope and objectives. Best practices are identified to ensure adherence to industry standards and maximize efficiency. Moreover, defining the desired Quality of Service (QoS) metrics is paramount to meet performance expectations. Integration needs are assessed to facilitate seamless interoperability with existing systems. Additionally, consideration is given to Commercial off-the-shelf (COTS) products that may fulfill specific requirements and streamline development efforts.
In crafting the System Architecture document, meticulous attention is given to standard architectural details, encompassing key constraints, assumptions, and associated risks. This comprehensive approach ensures a clear understanding of the project's scope and potential challenges. Moreover, detailed mapping of metrics is conducted to address stakeholder concerns effectively, aligning architectural decisions with project objectives. The rationale behind the selection of architectural principles and tradeoff considerations is elucidated, providing insight into decision-making processes. Finally, the document outlines expected quality metrics, ensuring that the architecture description aligns with targeted performance goals and quality standards.
