Welcome to the Systems Design Series, a practical and clear gateway to understanding systems design through volatility-based decomposition. Here you will find accessible explanations, an applicable framework, and examples that make understanding easier whether you are exploring architecture for the first time or designing large-scale systems.
Series overview: This series explains fundamental and advanced systems design concepts using THE METHOD. Rules, fundamentals, the framework, and practical examples are covered. It is inspired by the book Righting Software by Juval Löwy and is intended for those seeking to build a solid foundation and for professionals who wish to deepen their expertise. Basic programming knowledge helps, but if you are new, I recommend starting from the first article.
About the author and Q2BSTUDIO: I am an engineer with experience in both high-paced startups and Fortune 500 Big Tech companies, designing systems that support millions of users, intelligent data-driven solutions, and solving challenges in security and distributed systems. I am also part of Q2BSTUDIO, a custom software and application development company specializing in artificial intelligence, cybersecurity, and cloud services. At Q2BSTUDIO we offer custom applications and custom software, artificial intelligence services for businesses, AI agents, Power BI and business intelligence services, as well as AWS and Azure cloud services management to deploy secure and scalable solutions.
Collaboration and learning: My ideas come from professional practice, working with highly experienced engineers, and continuous learning from books and technical resources. I share this knowledge so the community can grow alongside me and to help teams make smarter architecture decisions.

Explore the series and key articles: 1. System Design Basics Why The Right Method Matters translated and adapted for the series. 2. Why functional decomposition leads to poor systems design. 3. Anti-design thinking in system design. 4. Volatility-based decomposition System design example. 5. Principles of volatility-based decomposition in systems design. 6. Template for systems design using THE METHOD. 7. Design errors in system design with THE METHOD. 8. Systems design is not about requirements but about change. 9. Practical example of systems design using THE METHOD. Each article is intended to be read independently, although some build concepts progressively.
How to navigate the series: Most articles are independent; if you are new, start from the first one and proceed in order. If you are looking for specific topics, use keywords such as custom applications, custom software, artificial intelligence, cybersecurity, AWS and Azure cloud services, business intelligence services, AI for businesses, AI agents, and Power BI to locate relevant content within the series and in Q2BSTUDIO resources.
About Q2BSTUDIO services: Q2BSTUDIO develops custom solutions that integrate artificial intelligence, advanced analytics, and cybersecurity for businesses of all sizes. We offer implementation services on AWS and Azure cloud services, business intelligence services consulting, creation of AI agents, and Power BI projects for visualization and decision-making. Our custom software and custom application services ensure adaptability, security, and scalability according to business needs.
Why follow this series: You will learn to identify which parts of a system change most frequently and how to isolate that volatility to minimize the cost of change. This approach improves maintainability, facilitates evolution, and reduces operational risks while staying aligned with business objectives.
Practical tips: When applying THE METHOD, prioritize identifying volatility points, design clear boundaries, define stable contracts between components, and protect critical areas with cybersecurity practices. Complement the design with deployments on AWS and Azure cloud services to leverage scaling and resilience, and use business intelligence and Power BI tools to measure impact and guide decisions.
Stay connected: Save this article as a series reference, follow the content on dev.to, and share it with colleagues who benefit from solid systems design practices. If you are looking for specialized consulting in artificial intelligence, AI for businesses, AI agents, Power BI, custom applications, or security, Q2BSTUDIO can support you throughout the entire project cycle from strategy to delivery.
Final note: This series is both a fundamentals guide and a practice lab for systems designers.
