openshift origin vs openshift online vs openshift enterprise VS OPENSTACK


Please explain these four in layman's terms.
  • openshift online
  • openshift origin
  • openshift enterprise
    &
  • openstack and devstack

I have read these on wiki but I am not able to understand them that what are they and how should I use them.

I know, they are cloud services.
First three are PAAS (Platform as a service) and last is IAAS (Infrastructure as a service)

IAAS provides bootable virtual machines, networking, block storage andobject storage.
PAAS provides the necessary parts to quickly deploy and run a LAMP application: the web server, application server, application runtimes and libraries.

but don't know how to install and use them.

Please help to make me understand them.

Thanks

--Kind Regards
Sam

Where did you read this wiki, Sam?

OpenShift Online is Red Hat’s hosted public PaaS that offers an application development, build, deployment, and hosting solution in the cloud. (or RH hosted)

and
OpenShift Enterprise takes the same open source PaaS platform that powers the OpenShift Online hosted service and packages it for customers who want an on-premise or private cloud deployment. (Possibly self-hosted/industrial solution)
FAQ

OpenStack is a free and open-source software cloud computing platform.[2] It is primarily deployed as an infrastructure as a service (IaaS) solution.
Documentation

So, this is Redhat's spin on "OpenSource 'Cloud' Services"? Is my guess.
Taking the I in IaaS and turning it into the P in PaaS and generating a revenue stream.

See also http://en.wikipedia.org/wiki/Cloud_c...Service_models

I signed up for OpenShift, (since I'm in the business)

Thanks for the all three links but still it is hard to understand.

I read it On wikipedia, but it is in technical terms and really hard to understand it. I want it in Layman's terms.

I have to understand it then I have to install it then I have to use it and I am stuck on first step.

Well, not to discourage you from acquiring more skill, I have to say that if you don't understand the subject, far be it from me to explain it to you.
And I'm "in the business" of cloud hosting.

I can partially explain some of these service models in laymen's terms...

Infrastructure as a service I can provide everything to my client from the "wheels up".
I have the hardware, software, and expertise to provide an entire entity of host(s) to solve the need.
Think physical server.

Platform as a service
I can provide IaaS with an additional "flavor".
Think physical server + Debian, Ubuntu, or CentOS

Software as a service Just need a *sql database
Think physical server + Linux + program (mysql/mail/web/tomcat...)

What is the first step as you understand it?

Thanks for giving me clear Idea...

I have tried to installed devstack on my ubuntu but I dont know how to use it.
The stack.sh script looks good but it is too much complicated, I hope it is installed on my system as IAAS.

Thanks again.
