Part of our larger question centers around the viability of tying instances directly to a provider network. Being that we only operate a private cloud for internal consumption, doing so would have some attractive upsides; tenants clamor for the IP inside their instance to be the same as the floating IP that the outside world sees, but nobody's ever asked us about the ability to roll their own network topology, so we think we could probably do without that.<br><div class="rte-style-maintainer" style="font-size: small; font-family: 'Courier New', Courier; color: rgb(0, 0, 0);"data-color="global-default" bbg-color="default" data-bb-font-size="medium" bbg-font-size="medium" bbg-font-family="fixed-width"><br><div class="bbg-rte-fold-content" data-header="From: Neil.Jerram@metaswitch.com" data-digest="From: Neil.Jerram@metaswitch.com" style=""><div class="bbg-rte-fold-summary">From: Neil.Jerram@metaswitch.com </div><div>Subject: Re: [Openstack-operators] Anyone using Project Calico for tenant networking?<br></div></div><blockquote>On 05/02/16 18:19, Ned Rhudy (BLOOMBERG/ 731 LEX) wrote:<br>> Hello operators,<br>><br>> We're continuing to investigate different cloud networking technologies<br>> as part of our project to migrate from nova-network to Neutron, and one<br>> that's come up frequently is Project Calico<br>> (<a spellcheck="false"bbg-destination="rte:bind" href="http://www.projectcalico.org/"data-destination="rte:bind">http://www.projectcalico.org/</a>).
