Vasu:
    VNFCs are mapped to VDUs, which are mapped to VMs (OS::Nova::Server)

Multiple VDUs are specified in the template like this:

vdus:
  vdu1:
    id: vdu1
    image: image_for_vdu1
    ......

  vdu2:
    id: vdu2
    image: image_for_vdu2
    .....

  .....

Auto-scaling is not currently supported but there is an open blueprint and a spec has been started.

Thanks Bob for the Sample.

I have one more query, In a multi node node OpenStack environment do we need to add anything on compute nodes from Tacker front or just enabling Tacker on controller node is sufficient?

Thanks in advance.

Regards,
 Vasu.

Hi Vasu:
    The simple answer is no, there is nothing required on the compute nodes for Tacker. The more complicated answer is still no, but depends on your definition of multi-node OpenStack. Tacker is a standalone server that can be configured to work with a single OpenStack keystone endpoint with a single Heat engine. If there are multiple availability zones configured within keystone, Tacker can take advantage of them by specifying them in the template.

Does that help?
