<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">I have
been getting up to speed on the Neutron LBaaS implementation and have been
wondering how to make it fit our needs in HP public cloud as well as as an
enterprise-grade load balancer service for HP Openstack implementations. We are
currently using Libra as our LBaaS implementation and are interested in moving
to the Neutron LBaaS service in the future.</span></p>

<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">I have
been looking at the LBaaS requirements posted by Jorge at:</span></p>

<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">When we
started looking at existing packages for our LBaaS service we had a focus on
requirements needed to create a managed service where the user would just
interact with the service APIs and not have to deal with resiliency, HA,
monitoring, and reporting functions themselves. Andrew Hutchings became the HP
Tech Lead for the open source Libra project. For historical reasons around why
we decided to contribute to Libra see:</span></p>

<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">We would
like to discuss adding the concept of “managed services” to the Neutron LBaaS
either directly or via a Neutron LBaaS plug-in to Libra/HA proxy. The latter
could be a second approach for some of the software load-balancers e.g. HA
proxy since I am not sure that it makes sense to deploy Libra within Devstack
on a single VM.</span></p>
<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif"> </span></p>
<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">Currently
users would have to deal with HA, resiliency, monitoring and managing their
load-balancers themselves. As a service provider we are taking a more
managed service approach allowing our customers to consider the LB as a black
box and the service manages the resiliency, HA, monitoring, etc. for them.</span></p>
<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif"> </span></p>
<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">We like
where Neutron LBaaS is going with regards to L7 policies and SSL termination
support which Libra is not currently supporting and want to take advantage of
the best in each project.</span></p>
<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">We have
a draft on how we could make Neutron LBaaS take advantage of Libra in the
back-end. </span></p>

<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">While
this would allow us to fill a gap short term we would like to discuss the
longer term strategy since we believe that everybody would benefit from having
such “managed services” artifacts built directly into Neutron LBaaS.</span></p>

<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">There
are blueprints on high-availability for the HA proxy software load-balancer and
we would like to suggest implementations that fit our needs as services
providers.</span></p>

<p class="MsoNormal" style="background-repeat:initial initial"><span style="font-size:9pt;font-family:Arial,sans-serif">One
example where the managed service approach for the HA proxy load balancer is
different from the current Neutron LBaaS roadmap is around HA and resiliency.
The 2 LB HA setup proposed (<a href="https://blueprints.launchpad.net/neutron/+spec/lbaas-ha-haproxy" target="_blank">https://blueprints.launchpad.net/neutron/+spec/lbaas-ha-haproxy</a>)
isn’t appropriate for service providers in that users would have to pay for the
extra load-balancer even though it is not being actively used. An
alternative approach is to implement resiliency using a pool of stand-by
load-and preconfigured load balancers own by e.g. LBaaS tenant and assign
load-balancers from the pool to tenants environments. We currently are using
this approach in the public cloud with Libra and it takes approximately 80
seconds for the service to decide that a load-balancer has failed,<span class=""> </span>swap the floating ip and update the
db, etc. and have a new LB running.</span></p>
