+- **React frontend:** Uses react query to load data from the two apis and display the result.
 - **Node.js and Go APIs:** Both have `/` and `/ping` endpoints. `/` queries the Database for the current time and the number of requests for each api recorded within the database, and `/ping` returns `pong`
 - **Postgres Database:** An empty PostgreSQL database with no tables or data. Used to show how to set up connectivity. The API applications execute `SELECT NOW() as now;` to determine the current time to return.
 - **Python Load Generator:** Queries one of either the Node.js or Go APIs at a configurable speed.
