Subject [jira] [Commented] (CLOUDSTACK-576) PaaS Enablement: Composite Application Blueprints
Date Tue, 11 Dec 2012 10:45:21 GMT


Alex Heneveld commented on CLOUDSTACK-576:

Thanks all.  Great comments Jie.  Seems like we're in general agreement that we want something
lightweight, based around Cloudstack concepts, and supporting the main vApp/cloudformation
functionality.  It *must* support the ability to:

* launch a set of VM's
* specify template ID and order/dependencies
* specify user/pass/keys on VM's where supported
* specify network configuration

Additionally we've learned from how people use the earlier approaches and this *should* be
designed so that:

* popular config tools can be used -- including bash, chef, puppet, package managers (eg rpm),
paas (eg openshift cartridges) -- but without depending on these or coding to them
* hooks for runtime management/automation are available -- e.g. scaling, HA/DR -- again through
optional and flexible mechanisms
* these blueprints and instantiations are integrated with the UI and the ecosystem (e.g. marketplace?)

I'm happy with this.  Anything I've missed or we should add at this point?

What's the recommended next step?  Is there a standard requirements or feature spec document
to put forward?  (We have a stab at this above but is there an official format?)

Personally I'd like to get some mock-up proposals for {X,YA}ML syntax and GUI to discuss.
 Ideas welcome ... I'll start working on the same.

> Given the level of interest in CloudStack as a platform for private, hybrid and public
cloud one of the gaps is support for composite/multi-tier application blueprints comparable
to VMware vApp and CloudFormation templates without necessarily slavishly following either
of them. This is almost certainly a new component. One that will leverage/enhance the API/AWSAPI
components amongst others.
