[ Microservice architecture 바로 알기 ]
Slidesahre, Facebook, 각종 블로그, 사이트등을 통해 얻은 다양한 자료를 정리해 볼까하며 개인적으로 끄적거리는 중인 자료입니다.
간단한 세미나에서 공유하고 잘 완성해 공유하려다 근래 잉여력이 바닥인지라 ... 그냥 투척합니다. 요즘 아몰랑...... 하고 마구 투척하는 것도 유행인듯하니... ㅋㅋ
다양한 클라우드플랫폼, CI/CD의 성숙, DDD, 오픈소스.. 등등등 Micro service architecture를 이야기하기에 기술적인 환경은 어느 정도 준비가 되었다고 봅니다.

여기서는 이러한 부분에 대한 내용을 다루며
조직이나 커뮤니케이션에 대한 부분은 이야기 하지 않습니다 ^^;
저도 답을 찾아 방황하는 중이에요~~~ +_+
