1. Cloud Native computing focuses on running containerized microservices at scale through technologies like Kubernetes. The Cloud Native Computing Foundation promotes this approach. 2. Games can benefit from a Cloud Native approach by running in-game and out-game processes as microservices on Kubernetes, including matchmaking, shops, rankings, and more. 3. Serverless computing through Functions as a Service (FaaS) allows code to be executed in response to events, reducing costs and speeds up development cycles for game processes like item purchases or notifications. Cloud Z's FaaS platform demonstrates running game functions.

1 No infrastructure management
인프라를 프로비저닝 하거나 관리의 불필요
코드만 작성하고 등록함으로 코드를 쉽게 실행
2 Event-based code execution
여러 가지 3rd 제품과 통합하여 코드를 트리거 가능
원하는 웹, 모바일 또는 백엔드 애플리케이션에서
HTTP를 통해 바로 코드를 호출 가능
3 Lower cost
함수가 실행 될때만 100밀리초 단위로 요금을 지불
테스트를 통해 자원을 최적화하고 미호출시 미과금
4 Faster release cycles
프로덕션 코드를 아주 빨리 프로토타이핑 가능
비즈니스 로직에만 집중하여 개발속도가 향상
전체 개발주기 단순화
