이 리포지토리는 "DevOps"의 기본적인 지식을 학습해 나가기 위한 나의 여정을 문서화 하기 위해 사용합니다. 2022년 1월 1일에 여정을 시작할 예정이며 90일이 소요됩니다. 딱 마침 1월 1일부터 3월 31일까지 입니다.

최근 들어 문서를 만드는 이유는 다른 사람들이 나의 문서를 통해 무엇인가를 얻을 수 있고, 또한 자료들이 많이 강화될 수 있다고 믿기 때문입니다.

목표는 하루 한 시간씩 90일 동안 "DevOps"의 13가지 영역에 대한 기본적인 지식을 학습하는 것입니다.

"DevOps"에 대한 **모든 것들을 다루지는 않습니다** 하지만, 전반적인 이해화 학습을 돕는 영역에 대해서 다루게 됩니다.
