--- prelude: | For the OpenStack Stein release, the Octavia team is excited to announce support for: Octavia flavors, TLS client authentication, backend re-encryption, and object tags. * Octavia flavors allow an operator to define "flavors" of load balancers, such as "active-standby" or "single" using the amphora driver, that configure the load balancer topology. The Amphora driver also supports specifying the nova compute flavor to use for the load balancer amphora. * TLS client authentication allows the listener to request a client certificate from users connecting to the load balancer. This certificate can then be checked against a CA certificate and optionally a certificate revocation list. New HTTP header insertions allow passing client certificate information to the backend members, while new L7 rules allow you to take custom actions based on the content of the client certificate. * Backend re-encryption allows users to configure pools to initiate TLS connections to the backend member servers. This enables load balancers to authenticate and encrypt connections from the load balancer to the backend member server. * Object tags allow users to assign a list of strings to the load balancer objects that can then be used for advanced API list filtering.
