Stackato (ActiveState's PaaS) auto-scales on OpenStack nicely. I just finished deploying it on Folsom <br><br>You can find the Stackato docs on auto-scaling are here, and do include an OpenStack section for each step:<div>

Yes, we use it here, but still finding to configure with OpenStack, to<br>
bring scale in this case communicate with openstack nova controller,<br>
we just use it now here..<br>

You could use the heat project to provide autoscaling.<br>
The way this would work is you:<br>
1 create an CloudFormations style template with your application (OpenShift/CloudFoundry)<br>
2 you setup an autoscale group and alarm resource in the template<br>
3 you post the metric of interest in your application to our Cloudwatch<br>
(see the calls to cfn-push-stats)<br>
as an example look at:<br>
<a href="https://github.com/heat-api/heat/blob/master/templates/AutoScalingMultiAZSample.template" target="_blank">https://github.com/heat-api/<u></u>heat/blob/master/templates/<u></u>AutoScalingMultiAZSample.<u></u>template</a><br>
<br>
What happens is you setup a threshold that triggers a scale up and scale down action.<br>

Have you hearad BOSH, a deployment tool for CloudFoundry on cloud(including<div><div><br>

Hi All<br>
<br>
Anyone can give me reference, related to scaling PaaS system in OpenStack?<br>
<br>
how (more basic better) scalable is implementing PaaS in OpenStack?<br>
<br>
right now, we create virtual machine and install ubuntu inside, and<br>
run CloudFoundry or OpenShift to make it PaaS enable.<br>
<br>
my target for PaaS is to run our Java apps inside cloud environment.<br>
<br>
in another world, we have Liquid VM, but it is not opensource yet,<br>
part of Java VE Virtual Edition. The JVM can boot direct from the<br>
hypervisor.<br>
<br>
I still researching the theory behind scalability of cloud esp in<br>
openstack + cloudfoundry.<br>
<br>
F<br>
