7. The Use Case – Our minimal requirements
A solution for our NON-persistent servers, such as the Web-
tier and the App tier
Be able to scale to thousands of VMs with commodity servers
and in a cost efficient manner
Transform our infrastructure to PAAS style.

15. What’s Cooking in our LAB – Operations and Control
Provisioning
API
NOC will provision new
VM’s, install physical
servers, deploy new services
and upgrade existing ones
&
Ceilometer
With the help of HEAT and
Ceilometer we’ll be able to
apply auto-scaling to many of
our clusters on the WEB and
APP tier.

16. Why is Openstack so Dear to Our RnD & QA?
Get thier own quota to provision VM’s
Can set thier own private LBs
Same keys and meta data deployed to all servers
No need for big budgets and settling for fewer VMs
Production compliant
RnD’s code is
automatically
delivered to
production – Not yet
deployed
&
HIERA
& Gerrit
