Well, one of the main reason to choose an open source product is to
avoid vendor lock-in. I think it is not <br>

we were thinking about is a Network Function (e.g. IMS Nodes)
implementation in which the high availability is based on
OpenSAF. In this scenario there is an Active/Standby cluster
of 2 System Controllers (SC) plus several Payloads (PL) that
boot from network, controlled by the SC. The logic of which
service to deploy on each payload is inside the SC.<br>
<br>
In OpenStack both SCs and PLs will be instances running in the
cloud, anyway the PLs should still boot from network under the
control of the SC. In fact to use Glance to store the image
for the PLs and keep the control of the PLs in the SC, the SC
should trigger the boot of the PLs with requests to
Nova/Glance, but an application running inside an instance
should not directly interact with a cloud infrastructure
service like Glance or Nova.<br>
