I guess you would call this PaaS provisioning.
It seems like you have a good handle on process.
Few more things to consider:
You may want to look into autoscaling options - to spin up more
PaaS slave nodes.
The templates for PaaS engine and PaaS slave nodes would make use
of metadata to auto configure. In fact, you don't have to create
specific templates for Engine/Slave if time to provision is not of
essence (probably unlikely). Entire script or pointer to install the
script can be passed through metadata.
Consider making use of groups feature to group node types
Last but not least, you did not mention what type of cloud you are
running - private or public.

Hi List
First of all, thanks to the CloudStack developer and user community
for an excellent piece of software!
I'd like to understand the best way of implementing a PaaS layer on
top of a CloudStack 4.5 based IaaS.
The ideal (to me) is for the PaaS layer to be integrated to the point
that PaaS can be provisioned by the end-user from the same interface
as infrastructure is provisioned (the C.S web via), and/or for
something like a PaaS templating syntax to be available for automated
provisioning of PaaS on on CloudStack.
Since C.S does not appear to have "native PaaS" integrated with it,
the options would appear to be something like this:
a) Implement a given PaaS with templates as a service offering
b) Automate PaaS template deployments using cloudmonkey or the C.S API
c) Install a PaaS management layer like OpenShift or Stackato 'on top'
of CloudStack
Are these all the current options for implementing integrated PaaS on
CloudStack? What would be the "best" approach (i.e the most tightly
integrated with C.S from the end-user perspective) ?
Cheers,
Traiano
