@ -70,20 +70,26 @@ should be possible for you to write an Octavia networking driver for your SDN
environment, which can be a drop-in replacement for the standard Neutron
networking driver in Octavia.
It is important for you to know that Octavia is not necessarily designed as a
complete replacement for the Neutron LBaaS project. That is to say, Octavia is
designed to "plug in" to Neutron LBaaS in the same way that any proprietary
vendor solution would: through a Neutron LBaaS version 2 driver interface. You
could think of Octavia as an "open source vendor" for Neutron LBaaS, rather
than as a substitute for Neutron LBaaS. For this reason, we recommend that
tenants configure load balancing services with Octavia through the Neutron
LBaaS version 2 CLI and API.
As of Pike, it is recommended to run Octavia as a standalone load balancing
solution. Neutron LBaaS is deprecated in the Queens release, and Octavia is its
replacement. Whenever possible, operators are **strongly** advised to migrate
to Octavia. For end-users, this transition should be relatively seamless,
because Octavia supports the Neutron LBaaS v2 API and it has a similar CLI
interface. Alternatively, if end-users cannot migrate on their side in the
forseable future, operators could enable the experimental Octavia proxy plugin
in Neutron LBaaS.
Soon, Octavia will supplant Neutron LBaaS as the load balancing solution for
OpenStack. At that time, third-party vendor drivers that presently "plug in"
to Neutron LBaaS will plug in to Octavia instead. For end-users, this
transition should be relatively seamless, because Octavia supports the Neutron
LBaaS v2 API and it has a similar CLI interface.
It is also possible to use Octavia as a Neutron LBaaS plugin, in the same way
as any other vendor. You can think of Octavia as an "open source vendor" for
Neutron LBaaS.
Soon, Octavia will support third-party vendor drivers just like Neutron LBaaS,
and will then fully replace Neutron LBaaS as the load balancing solution for
OpenStack. At that time, third-party vendor drivers that presently "plug in" to
Neutron LBaaS will plug in to Octavia instead.
