Re: [Xen-API] Cloudstack or Openstack


So, I'm going to get off topic (maybe, arguably, it's still within topic).

Looking at the CloudStack website, they said the software is to manage
a large number of virtual machines (VMs) as a cloud computing
platform. What precisely does it help you manage?

For example, I've been trying to find a technology to help build and
support an elastic cloud computing platform (i.e. a Hadoop, HBase, or
Accumulo cluster) with some significant level of automation involved.
If I use XCP as the underlying virtualization platform, will
CloudStack be able to interface with it to create an elastic,
virtualized cloud computing (Hadoop) cluster for me?

What I've been doing manually is 1) create a VM and 2) configure a VM
for each node I want to add to the cluster. Needless to say, this is
time-consuming and error-prone. Could something like this be achieved
with CloudStack (or OpenStack or OpenNebula)? The other day I read
about another product, Eucalyptus, and I wonder how this fits into the
picture; is this software meant to run on top of Xen, XCP, or both?

I know I see diagrams on the XCP website/pages that says XAPI is
exposed to 3rd party management tools. But it's difficult to say how
these 3rd party tools are manipulating XCP and for what purposes.

Do I need other technologies/software (i.e. Chef or Puppet)? Right
now, there's too many options and too much marketing content I cannot
really discern the products' capabilities.

Any help is appreciated.
