The architecture of a potential experiment platform is depicted in the diagram below. This content of the visual is from the book: "Trustworthy Online Controlled Experiments" (redrawn by me). The platform contains 4 high-level components.

## Key Components

*   **Experiment definition, setup, and management via a UI.** They are stored in the experiment system configuration.

*   **Experiment deployment** to both the server and client-side (covers variant assignment and parameterization as well).

*   **Experiment instrumentation.**

*   **Experiment analysis.**
