Octavia

Octavia is the OpenStack load-balancing-as-a-service (LBaaS) project that provides scalable, programmable L4–L7 load balancing for cloud environments.

  • Cloud-native load-balancing-as-a-service for OpenStack clouds (networking / Load Balancer as a Service (LBaaS)).
  • Implements software-based load balancers using amphorae virtual machines or containers (load balancing infrastructure).
  • Integrates with OpenStack Neutron and other OpenStack services for networking, identity, and orchestration (cloud infrastructure integration).
  • Supports health monitoring, SSL/TLS termination, and multiple listener and pool configurations (application delivery / traffic management).
  • Provides a Representational State Transfer (REST) Application Programming Interface (API) and pluggable driver architecture for different load balancer providers (API / extensibility framework).

More About Octavia

Octavia is the load-balancing-as-a-service (LBaaS) component of the OpenStack ecosystem, designed to deliver L4–L7 load balancing for applications running on OpenStack-based clouds (networking / application delivery). It addresses the need for tenant-isolated, programmable load balancing that integrates directly with OpenStack networking, compute, and identity services. Octavia is built to operate as a multi-tenant service where each tenant can provision and manage its own load balancers through standardized APIs.

At its core, Octavia uses an architecture based on “amphorae,” which are virtual machines or containers that run the load balancer software (load balancing infrastructure). The Octavia controller manages the lifecycle of these amphorae, including provisioning, configuration, failover, and scaling. This design allows operators to deploy software-based load balancers on top of standard compute resources, avoiding dependency on proprietary hardware appliances while still providing enterprise traffic management features.

Octavia exposes a REST API for tenants and operators, enabling integration with orchestration tools and higher-level automation (API / automation integration). It supports listeners, pools, health monitors, and L4–L7 policies that define how client traffic is distributed to backend application servers. Features commonly include multiple protocols such as Hypertext Transfer Protocol (HTTP), HTTPS, and Transmission Control Protocol (TCP), SSL/TLS termination, and different load balancing algorithms (application delivery / traffic management). Health monitoring functions track the status of backend members and automatically remove or re-add them to pools based on configured checks.

In OpenStack environments, Octavia typically integrates with Neutron for virtual networking, Keystone for authentication and authorization, and other OpenStack components for resource management (cloud infrastructure integration). It can operate as a provider for Neutron LBaaS or as the standalone load balancing service in newer OpenStack networking models. The architecture supports a pluggable driver framework so that different load balancer technologies or provider implementations can be integrated behind a common API (extensibility / provider integration).

For enterprise and institutional users, Octavia provides a centralized way to offer load balancing to multiple tenants as part of a private, public, or hybrid OpenStack cloud (multi-tenant network service). Operators can define service flavors, quotas, and policies, while application teams interact through APIs or dashboards to create and manage load balancers alongside their compute instances and networks. This positions Octavia in an infrastructure directory as an L4–L7 software load balancer and LBaaS platform for OpenStack, suitable for integration into cloud networking, application delivery, and automated deployment pipelines.
