Frame the problem
Start with the user need, constraints, scale, consistency, latency, recovery goals, and what failure the system must survive.
Technology Architecture
Learn with diagrams, code, systems and practical examples.
Architecture library · reason from constraints
Learn to defend a design, not just draw it.
SubjectVision architecture guides start with the problem, trace the request and data flow, stress the failure modes, and make every trade-off explainable. Service names come after the reasoning.
A repeatable architecture habit
Use the same reasoning loop on every system.
The goal is not to memorize a preferred stack. It is to make the smallest defensible design, then know exactly where it can break.
Follow the flow
Trace the request and data path end to end. Every boundary should have an owner, a contract, and a reason to exist.
Stress the design
Ask what happens when dependencies slow down, retries duplicate work, partitions skew, regions fail, or operators must recover the system.
Defend the trade-off
Explain what the design improves, what new complexity it creates, and when a simpler architecture would be the better engineering decision.
Published patterns
Study one system deeply before collecting more diagrams.
Each reference is intentionally substantial. New patterns earn a page only when they can teach a real flow, concrete failure behavior, security and cost consequences, and practical decision-making.
Distributed systems Intermediate
Event-Driven Architecture
Learn event-driven architecture through producers, brokers, consumers, delivery guarantees, failure modes, security, cost, and design trade-offs.
