Video explanation
A client, service nodes and database form a chain with a dashboard of traces and status indicators. The drawing illustrates layered architecture without identifying an exact implementation.
Separate responsibilities
Clients initiate operations, services process logic and storage retains data. Separating them exposes boundaries.
Flow and dependencies
Connections represent calls or data dependencies, not a guarantee that every operation follows the same path.
Observability
Traces and status panels help visualize operation. Animation readouts are not measured production metrics.
