Octavia Roadmap

This document describes the development roadmap for the OpenStack Octavia load balancer as a service project. It should be updated periodically by Octavia team members as the group agrees on development priorities.

Long-term timeline

Major milestone: Octavia Version 0.5

Description: First generally usable release of Octavia. Delivers load balancing services on multiple Nova VMs (amphora). Single, centralized command and control (not scalable).

OpenStack release target: Liberty

Neutron-LBaaS progress:

• Flavor support
• TLS support
• Updated horizon UI
• Octavia driver for Neutron LBaaS

Octavia progress:

• Octavia delivers all functionality of Neutron LBaaS user API
• Horizon UI updates for Neutron LBaaS v2
• Octavia amphora image building scripts
• Neutron LBaaS driver interface for Octavia
• Non-voting Neutron third-party CI for Octavia to ensure Neutron code changes don't break Octavia (possibly updated to voting CI, once Octavia supplants legacy reference driver).
• Command-and-control layer handles:
  • Octavia amphora lifecycle management
  • Octavia amphora monitoring
  • Octavia amphora command and control
  • Neutron LBaaS service deployment
• Become reference implementation for Neutron LBaaS
• Amphora spares pool support
• Basic amphora failover support

Major milestone: Octavia Version 0.8

Description: Operator-scale release of Octavia. Delivers load balancing services on multiple Nova VMs (Amphora), and has scalable command and control layer.

OpenStack release target: Mitaka

Neutron-LBaaS progress:

• L7 switching support
• Horizon dashboard for LBaaSv2

Octavia progress:

• Resilient topologies for Octavia amphorae (ie. active/standby)
• L7 switching support
• Hooks for Heat integration
• Fully scalable and HA command-and-control layer
• Single call create

Major milestone: Octavia Version 0.9

Description: Retire LBaaS v1 API, add support for IPv6, and additional neutron network configurations.

OpenStack release target: Newton

Neutron-LBaaS progress:

• LBaaS API v1 has been removed
• Single call create
• Support for creating load balancers using a neutron network id

Octavia progress:

• Add IPv6 support
• Support for host routes and subnets without DHCP enabled
• Amphora certificate and key storage is now in an encrypted ramfs

Major milestone: Octavia Version 0.10

Description: Octavia / LBaaS spin out of neutron, start work to merge neutron-lbaas into Octavia

OpenStack release target: Ocata

Neutron-LBaaS progress:

• Namespace driver agent rescheduling
• Namespace driver haproxy process monitoring

Octavia progress:

• Adds keystone suport to Octavia API
• Adds quota support to Octavia API
• Adds policy support to Octavia API
• Amphora images now support systemd
• Amphora images can now be built with Ubuntu Xenial
• Support for PKCS7 intermediate certificate bundles

Major milestone: Octavia Version 1.0

Description: Finish neutron-lbaas merge into Octavia and enable Active/Active topology

OpenStack release target: Pike

Octavia progress:

• Octavia v2 API compatible with neutron-lbaas v2 API
• OpenStack client plugin
• Admin API support for amphora upgrades
• Health monitoring on alternate IPs and/or ports

Major milestone: Octavia Version 2.0

Description: General enhancements and preparation for neutron-lbaas deprecation

OpenStack release target: Queens

Neutron-LBaaS progress:

• Neutron-LBaaS API pass through proxy to Octavia API
• Start deprecation of neutron-lbaas

Octavia progress:

• Octavia Dashboard enhancements
• Batch pool member enhancements
• Neutron QoS support for load balancer VIP
• Castellan support for TLS offload certificate storage

Major milestone: Octavia Version 3.0

Description: Enable Provider drivers and UDP protocol support

OpenStack release target: Rocky

Neutron-LBaaS progress:

• Maintenance - Under deprecation feature freeze

Octavia progress:

• Provider driver support
• UDP loadbalancing support
• Backup or "Sorry" page support
• Timeout configuration support per load balancer

Major milestone: Octavia Version 4.0

Description: Enable flavors and TLS enhnacements

OpenStack release target: Stein

Neutron-LBaaS progress:

• Maintenance - Under deprecation feature freeze

Octavia progress:

• Backend re-encryption
• Client certificate authentication
• Flavors
• Kernel TCP splicing

Major milestone: Octavia Version 5.0 - Work in Progress

Description: TBD

Note: These are planned goals for this release but not all of these goals may be accomplished in this OpenStack release.

OpenStack release target: Train

Neutron-LBaaS progress:

• Maintenance - Under deprecation feature freeze

Octavia progress:

• Active/Active topology ????

Considerations for Octavia 4.0+

The features described here are not presently planned for any official release of Octavia, but may make sense to develop at some point given user or operator demand (and may be moved to an earlier release cycle as a result of this), and probably still fall within scope of the larger Octavia project:

• ACL support
• Active/Active dynamic scaling
• Active/Active topology
• Additional balancing algorithm support
• Additional health monitor protocols
• Advanced logging configurations
• Amphora container support
• Backend member server "agent" support
• CA certificate management
• Compression support
• Content caching support
• DDoS mitigation
• Intelligent ECC certificate handling
• Fine grained ssl cipher and protocol configuration support
• Header insertion
• Health monitor content check
• Log offloading
• Integration with to-be-defined OpenStack GSLB project Kosmos
• OpenStack TaskFlow Jobboard support
• Performance enhancements
  • DPDK
  • PCI-Passthrough
  • SRIOV
  • FPGA
  • CPU pinning
  • Multi-process/multi-thread models in the load balancing engine
• Rewrite rules
• Shared health monitors
• Status change notifications via oslo messaging
• Status tracks another member
• Additional L7 protocol support (beyond HTTP)
• Advanced metrics / instrumentation support
