What is solution architecture?
Let’s begin with a straightforward definition: solution architecture is the practice of designing a complex series of engineering solutions that align IT programs and information assets with a company’s business strategy. This alignment ensures that the implemented digital solutions are scalable, sustainable, and effectively address the specific needs of the business.
For example, a retail company that wants to have greater supply chain effectiveness can be supported by a solution architect who designs an IT plan with embedded advanced analytics and real-time processing. This IT architecture allows the company to eliminate waste, lower inventory levels, and respond quickly to market changes. Tailored IT plan not only meets the short-term operational needs of the company but also sets it up for future growth and resilience.

An example might be designing a system with built-in compatibility for emerging technologies like AI and blockchain, ensuring it can seamlessly incorporate these innovations as they become relevant to the business.
What is the process of solution architecture?
The solution architecture process not only starts with acquiring the business requirements and assessing the current IT infrastructure, but also involves rigorous planning and coordination. After the business goals are understood, the architect examines the current technology platform to identify areas of gaps and opportunities. This is generally followed by a design phase, where a tailored solution is created specifically in alignment with business goals. The architect then chooses the most suitable technology stack and oversees its installation to ensure all the components work in concert and as per original design specifications. The overall process is one of ongoing tweaking and stakeholder feedback to ensure the solution remains aligned with evolving needs, markets, and new technologies.
10 Solution architecture principles
There are many different principles a good solution architect should follow. Here is an example of 10 common ones, though there are many more important considerations and the priorities change based on the project.
- Prioritize Reuse: Before considering new solutions, it’s crucial to look at reusing existing solutions. If a new solution is necessary, it’s more cost-effective to purchase than to build from scratch. This approach enhances cost-efficiency, reduces complexity, and speeds up market readiness. It also minimizes development risk by relying on well-tested, market-standard processes in packaged solutions, though it’s important to avoid excessive customization to keep maintenance costs manageable.
- Business-Centric Design: The design, development, and operation of solutions should be driven by business and functional processes. This alignment helps avoid the unnecessary costs of technology for its own sake and ensures that IT investments contribute directly to business objectives. It’s essential for processes to be designed around outcomes rather than functions, which may require organizational changes and a focus on both operational and technology monitoring.
- Centralization of Architecture Components: Centralizing architecture components simplifies management, enhances control, and promotes standardization, which in turn reduces costs. Key components like Enterprise Service Bus (ESB), API Management, and Business Intelligence should be centrally located to streamline governance and improve efficiency. In hybrid environments, it’s crucial to dictate that certain components be centralized in both locations.
- Secure Access Management: Access to IT systems must be securely managed through proper authentication and authorization. Only authorized users should have access to specific functionalities and data. This principle requires a holistic security approach to ensure these controls are effectively implemented and managed.
- Standardized Application Development: Emphasizing the reuse of existing components and skills helps reduce complexity and accelerates delivery. Maintaining company-wide software development standards, including code control and peer reviews, ensures consistency and leverages best practices. Automation in software factories checks for adherence to these standards.
- Scalability of IT Solutions: IT solutions should be selected and designed for scalability to accommodate growth. This includes both vertical and horizontal scaling as well as predictive monitoring of IT resource usage to manage capacity effectively and avoid system failures.
- Decoupling of Application Architecture: Decoupling the front and back ends improves flexibility, scalability, and performance tuning. This separation allows for independent updates and maintenance, reducing the impact of failures and facilitating better reuse across systems.
- Clear Components: All IT components must have clear ownership to define responsibility and accountability. This clarity helps manage costs and supports efficient design, maintenance, and changes to the components.
- Incremental Change: This principle emphasizes the importance of evolving an IT architecture gradually rather than attempting large-scale changes that can disrupt business operations and become tricky to track. By making changes incrementally, organizations can minimize risk, allowing for easier adaptation and troubleshooting.
- Contextual Relevance: Ideally, solution architecture should be designed to be contextual to the specific needs of the organization. This is not just the technical requirements, but also the business environment, industry standards, and regulatory considerations. By tailoring solutions to the unique business needs, it ensures a more realistic and efficient system.
Are you concerned your solution architecture lacks principles?
If your technology feels rigid, inefficient, or out of alignment with business goals, it might be time to evaluate your solution architecture. This reassessment can help identify gaps in your current framework and introduce new practices that better support your strategic objectives.
Here are a few warning signs that it’s really time to take a close look:
- Technology Shifts: If there’s been a significant advancement in technology or a new industry standard, it may be time to reassess your architecture to ensure it remains current and efficient.
- Business Growth or Change: Scaling operations, entering new markets, or changes in business strategy can necessitate a reevaluation of existing architectures to ensure they still align with business goals.
- Performance Bottlenecks: If certain processes start to lag or cannot handle increased loads, this might indicate that the architecture needs to be optimized for better performance.
- Security Breaches: Any security incident is a clear signal to review and possibly overhaul the architectural framework to enhance data protection measures.
- Integration Challenges: Difficulty integrating new tools or systems can suggest that the architecture is not flexible or open enough to accommodate necessary changes.
- Regulatory Compliance: Changes in legal or regulatory requirements may require modifications in the architecture to ensure compliance.
- Cost Inefficiencies: If the costs of maintaining your IT infrastructure are escalating, it might be time to look for more cost-effective solutions within your architecture.
Evaluating these aspects regularly ensures that the solution architecture effectively supports the business as it evolves. It’s also a good practice to conduct architectural reviews after major project milestones or annually. This proactive approach helps maintain an architecture that not only meets current needs but is also primed for future challenges and opportunities.
How evaluating solution architecture works
Periodic reviews ensure that the architecture remains relevant and effective. It’s like a health check for your IT systems. These tech health checks focus on current performance measures, alignment of business goals, and their adaptability to new technologies or market demands.
Assessing your solution architecture means examining its current shape and functionality to ensure that it aligns with your current strategic vision and operating needs.
Here is what an evaluation of this type would usually look for:
