When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.

역학
조합해 검사하도록 설계된다. 원자 단위로 작동하는 결합 기능을 검사하는 동안 전체 피트니스
함수는 실제로 이들의 결합을 깨뜨리지 않는다. 보안과 확장성 모두에 피트니스 함수를 보유
한 아키텍처를 가정해보자. 데이터의 부패도
staleness
는 보안 피트니스 함수의 주요 검사 항목이
다. 확장성을 검사할 때는 특정 레이턴시
latency
범위의 동시 사용자 수를 중요하게 본다. 개발자
는 확장성을 확보하기 위해 캐싱을 구현하며 확장성의 원자 피트니스 함수를 통과시킨다. 캐싱
기능을 끄면 보안 피트니스 함수도 통과한다. 그러나 전체 실행 상황에서 캐싱이 활성화되면
데이터 부패도가 지나치게 높아져 보안 피트니스 함수를 통하지 못한다. 따라서 전체 테스트도
실패하게 된다.
아키텍처 요소들의 모든 조합을 일일이 테스트하는 것은 불가능하므로, 아키텍트는 중요한 상
호작용을 선별하고 조합해 전체 피트니스 함수를 적용해야 한다. 이러한 선별력과 순위화를 통
해 아키텍트와 개발자는 특정 테스트 시나리오 구현의 난이도를 가늠하고 각각의 특성과 가치
를 평가할 수 있다. 아키텍처 문제들의 상호작용 자체가 아키텍처의 품질을 좌우하는 경우가
종종 있지만, 전체 피트니스 함수로 이러한 오류를 바로잡을 수 있다.
