## Deployment Concepts

Here you saw how to use multiple **workers** to **parallelize** the execution of the application, take advantage of **multiple cores** in the CPU, and be able to serve **more requests**.

 * {@code K}. If a key has not yet been associated with a value, its implicit value is zero.
