Cloud Foundry is an open source platform as a service (PaaS) that supports multiple cloud infrastructures like OpenStack. It provides a standard interface called the Cloud Provider Interface (CPI) that enables applications to be deployed and managed across different cloud infrastructures without vendor lock-in. Cloud Foundry uses an open source component model with buildpacks, runtimes, and service brokers to package and run applications on the platform. It has a large community of contributors and supports numerous programming languages through its buildpack ecosystem. The Linux Foundation now manages the Cloud Foundry project to prevent fragmentation and ensure its long-term support as the de facto open source PaaS.

The Open Source Way
From Redhat website,…
– 자유롭게 코드보기
– 자유롭게 공부하기
– 자유롭게 질문하기
– 자유롭게 개선하기
Open Source 복습
오픈 소스(open source)는 제작자의 권리를 지키면서 원시 코드를 누구나 열람할 수 있도록 한
소프트웨어 혹은 오픈 소스 라이선스에 준하는 모든 통칭을 일컫는다.

Open Source 가 기업에도 중요한 이유들
Cost Saving
– 심지어는 Redhat, Suse, Pivotal,… 등으로 부터 Enterprise Model을 사용시에도.
Quality
– Open Source 코드의 품질은 수많은 개발자들의 기여, 검토, 테스트로 부터 완성되며,
매우 견고한 코드를 생산해 냅니다.
– 공개된 표준에 맞추어 호환성을 유지
– 기술 공개 및 검증의 자유로움
Open source mitigates business risk
– 상업용제품은 오직 비즈니스 논리에 따라 코드관리가 중단 될 수 있지만 Open
source는 자발적 참여자와 Community 에 의하여 보다 지속적으로 지원된다.
– Open source는 벤더 제품의 종속을 피할 수 있다. (No vendor lock-in)

Rapid Innovation Requires a Combined Approach
PaaS
 Dramatically improve developer
experience
 Agile teams, rapid iteration
 Microservices, incubate open
source advancements (data and
apps)
 Continuous delivery, no planned
downtime
 Instant scaling of apps and data
services
 Automation and deployment
consistency at every step

PaaS 몇 가지 요건들
개방성과 지원 다양성 - PaaS 그 자체가 Open source 이자 Open
source 를 적극 지원해야 한다.
– 다양한 언어의 지원
– 최신 기술 수용
지속성 - PaaS는 IaaS의 OS 이다. 따라서 강력한 커뮤너티의
후원을 받아야 하며, 동시에 파편화 현상이 방지되어야 한다.
– 초기 Linux는 파편화 현상이 많이 발생
독립성(범용성) - IaaS Independent, Java, .Net, Docker 등
모두 수용
Standard - 다양한 OSS 커뮤너티의 OSS Product이 활용되는
범용적 cloud consumption engine 이어야 한다.
– No Lock-in

PaaS는 IaaS가 아니다.
적합한 PaaS의 Runtime 적절치 못한 PaaS의 Runtime
Lightweight containers, seconds
to thousands of instances
Heavy VM overhead and waste, several
minutes to change scale
12 Factor Compliant Bindings Some in-app configuration files
Built-in logging Retrieve logs from each VM..
Instant Blue/Green updates DNS changes, Downtime, in hours
Any cloud Specific cloud only
