Evolving Kubernetes networking: HAProxy's journey with Ingress, Gateway API & Fusion

This presentation examines three approaches to routing traffic within Kubernetes environments using HAProxy solutions. The speakers explore the established Ingress API, the emerging Gateway API standard, and HAProxy Fusion's advanced Service Discovery capabilities.

What you'll learn:

• Ingress Controller: Direct Pod routing to avoid extra hops, runtime configurability, and custom resource definitions for full HAProxy feature access.
• Gateway API: A newer Kubernetes networking standard (v1 in 2023) offering role-oriented design and extensibility, with HAProxy developing a Unified Kubernetes Gateway for community and enterprise use.
• HAProxy Fusion Service Discovery: Pod discovery, LoadBalancer support with automatic IP assignment via IPAM, and multi-cluster routing for active-active and active-passive configurations across regions and cloud providers.

The speakers also introduce a Replay system for troubleshooting large clusters and highlight a 450x performance improvement in update procedures.
