A Tale of Two Systems: Design and Reality

Every architect knows the feeling: the system you designed and the one that was actually built rarely look the same. In fast-moving environments, where speed often trumps structure, clean architecture can quickly give way to quick fixes and temporary solutions. The rise of AI has only accelerated this tension: new models and features appear weekly, and startups rush to deploy them first. How much design is enough when today’s requirements might change tomorrow? This session explores the widening gap between design and implementation, examining how to make pragmatic architectural choices without sacrificing long-term stability. Drawing from real-world experiences, it highlights strategies for balancing deliberate design with rapid iteration, understanding when to plan deeply and when to adapt. Attendees will gain practical insight into designing systems that evolve gracefully under constant change, building for today without blocking tomorrow.

The Architect’s Dilemma: Control vs Convenience

Few decisions challenge software architects more than choosing between control and convenience. Should you host PostgreSQL on EC2 for full control, use Amazon RDS for managed simplicity, or opt for Aurora DSQL for serverless scalability? Each path involves trade-offs around cost, speed, expertise, and risk. This session examines real-world architectural scenarios to show how to evaluate these choices systematically. Through practical examples, attendees will learn how to map business needs to technical decisions, balance short-term delivery with long-term flexibility, and assess the true total cost of ownership beyond cloud provider bills. The session also discusses how to align technology choices with team skills, compliance requirements, and business priorities. Ultimately, it encourages architects to focus on delivering value rather than pursuing complexity for its own sake.
