Hi Sumit,
<div><br>
</div>
<div>I also got confused with service VM and service instance definition. I assumed both being the same and hence the networks question.</div>

<div><br>
</div>
<div>We tried to separate policy from mechanism for this blueprint, and are trying to address the latter. I believe the logic for scaling, and or clustering multiple service VMs to map to a logical service instance would lie in the service plugin which realizes
the logical service instance.</div>
<div><br>
</div>
<div>Can you please elaborate on the service/use-case where you would need to plug the VM into different networks?</div>
<div><br>
</div>
<div>Thanks,</div>

</div>
<div>Is there any discussion so far on the scaling of VMs as in launching multiple VMs</div>
<div>for the same service. It would also have impact on the VIF scheme.</div>

</div>
<div>How can we plug these services into different networks - is that still being worked</div>
