Sukwon Choi's comment,May 8, 9:59 PM

가트너에 따르면 IaaS/PaaS/SaaS 간의 경계를 모호해지고 있다.

AWS와 같은 IaaS Leading 업체는 PaaS와 같은 기능을 추가하고 있다.
그 실례로 최근에 나온 OpsWorks나 Elastic Beanstalk, CloudFront와 같은 제품들을 이용하여 app의 deploy/scale을 쉽게 할 수 있도록 하였다.

또한 SaaS로 유명한 Salesforce.com은 그들의 통합 PaaS 환경인 Force.com/ Heroku 개발에 박차를 가하고 있다.

IaaS, SaaS는 여전히 견고한 시장임에 틀림없지만, 이 시장의 서비스 제공자들이 PaaS 시장으로 움직이는 현상은 점차 늘어나고 있다.

이러한 이유는,
첫째 vendor들이 더욱 다양한 소비자들에게 어필하기 위해서이고,
둘째 사용자들이 vendor들에게 더 많은 기능을 요구하고 있기 때문이다.

PaaS 사용자는 크게 Coders, DevOps, Rapid developers로 나누어진다.
Coder들은 프로그램 개발 이외의 것에 신경쓰고 싶어하지 않으며,
DevOps들은 app deploy 뿐만 아니라 VM/스토리지 등의 설정을 통해 튜닝할 수 있는 기능을 원하며,
Rapid developers는 force.com과 같이 coding 없이 app을 개발하고자 한다.

이러한 다양한 사용자들은 순수한 IaaS, PaaS, SaaS만으로는 만족하지 못하고 있다.
PaaS는 개발자가 Infra에 신경쓰지 않도록 해주지만, 개발자는 더 많은 control을 가지고 싶어하기 때문이다.

Blue Box라는 managed hosting + IaaS 업체는 최근 IaaS+ 정도로 생각되는 비지니스 모델을 들고 나왔는데, 이는 PaaS 서비스를 사용해본 고객을 끌어안으려는 전략으로 보이며, MS Azure 또한 IaaS와 PaaS를 융합하고 있음을 알 수 있다

Cloudify - Putting DevOps and PaaS together with Cloudify | Cloud PaaS BigData Hadoop CloudFoundry Java Ruby | Scoop.it
RT @fduthilleul: Was looking for differences/overlaps between DevOps & PaaS found this very good article from @natishalom http://t.co/DTHDfPq3 #devops #paas...

Via Maya DAN
JerryJung's insight:

DevOps and PaaS represent two different paradigms for delivering applications to the cloud.

DevOps - DevOps takes an automation approach - with DevOps we basically script the process of installation, configuration and deployment of the application stack. PaaS - PaaS takes an abstraction approach by abstracting the details of the cloud infrastructure from the developers. 

DevOps tends to cater to operations guys that want to maintain the flexibility and control over the infrastructure and PaaS caters more to developers who just want to write code and deliver it without worrying too much about the details of the underlying infrastructure.
