An interesting detail is that the percentage of the **CPU used** by each process can **vary** a lot over time, but the **memory (RAM)** normally stays more or less **stable**.

If you have an API that does a comparable amount of computations every time and you have a lot of clients, then the **CPU utilization** will probably *also be stable* (instead of constantly going up and down quickly).

TLS Termination Proxy로 사용할 수 있는 옵션은 다음과 같습니다:

* Traefik (인증서 갱신도 처리 가능)
* Caddy (인증서 갱신도 처리 가능)
* Nginx
* HAProxy

## Let's Encrypt { #lets-encrypt }

Let's Encrypt 이전에는 이러한 **HTTPS 인증서**가 신뢰할 수 있는 제3자에 의해 판매되었습니다.

인증서를 획득하는 과정은 번거롭고, 꽤 많은 서류 작업이 필요했으며, 인증서도 상당히 비쌌습니다.

하지만 그 후 **[Let's Encrypt](https://letsencrypt.org/)**가 만들어졌습니다.
