In the next chapters, I'll give you more **concrete recipes** to deploy FastAPI applications.

But for now, let's check these important **conceptual ideas**. These concepts also apply to any other type of web API. 💡

## Security - HTTPS { #security-https }

In the [previous chapter about HTTPS](https.md) we learned about how HTTPS provides encryption for your API.

 * instance retrieved from the map's {@linkplain Map#entrySet entry set} is a snapshot of that
 * entry's state at the time of retrieval; such entries do, however, support {@link
 * Map.Entry#setValue}, which simply calls {@link Map#put} on the entry's key.
 *
 * <p>The maps produced by {@code MapMaker} are serializable, and the deserialized maps retain all

*  limitation of liability shall not apply to liability for death or   *

*  jurisdictions do not allow the exclusion or limitation of           *
*  incidental or consequential damages, so this exclusion and          *
*  limitation may not apply to You.                                    *

#### Updates to apply
* New command `apply set-last-applied` *updates the applied-applied-configuration annotation* ([#41694](https://github.com/kubernetes/kubernetes/pull/41694), [@shiywang](https://github.com/shiywang))

* If a PR seems to be spam, meaningless, only to change statistics (to appear as "contributor") or similar, you can simply mark it as `invalid`, and it will be automatically closed.
