<p class="MsoNormal">Yes, to ensure availability the same application could be deployed<br>
across multiple availability zones/cells, as these can offer some<br>
level of independence of risk. The use-cases seemed to expect same<br>
network, which may not be achievable given the above, but ideally<br>
should be able to load-balance across zones/cells. Other cloud<br>
management solutions have moved to name based LB because of the above,<br>
is this something being considered?<o:p></o:p></p>
