Functions-as-a-Service
• 서버리스 아키텍처의 중심
• Function
– 그 자체로 일을 수행할 수 있는 작은 단위
– 어떤 입력을 받고 기능을 수행한 다음 아웃풋을 내는 형태
• Functions-as-a-Service (FaaS)
– Function 하나가 FaaS 플랫폼의 하나의 유닛으로 배포
– 프로비져닝, 배포하고, 스케일 업/다운, 빌링, 인증, 인가, 보안등을 제공
– 매우 빠르고 스케일도 매우 클 수 있으며 어떤 언어나 플랫폼에서도 수행가능

이상적인 Functions 플랫폼
• 오픈 소스 – 프로바이더에게 비종속적.
• 런타임 플랫폼에 자유 - laptop, server, cloud에서 모두 수행가능
• 쉬운 접근성 – 사용하기 쉽고 관리하기 쉬운 형태
• Docker 기반 – Docker 기반으로 수행
• 여러 툴 사용가능 - Kubernetes, Swarm, Mesos 등을 사용
