Load Balancer User Guide

Overview

Polystack Load Balancer distributes inbound application traffic across a pool of backend instances. Use the guides below to create load balancers, configure listeners and pools, set up health monitors, assign public floating IPs, and troubleshoot traffic issues.

Create a Load Balancer

Provision a new load balancer with a listener, pool, and health monitor in a single workflow.

Listeners

Add HTTP, HTTPS, TCP, and UDP listeners to an existing load balancer.

Pools

Manage backend member pools and configure traffic distribution algorithms.

Health Monitors

Configure TCP, HTTP, and HTTPS health checks to automatically remove unhealthy members.

Floating IP Assignment

Expose your load balancer VIP on a public network using a floating IP.

Troubleshooting

Resolve provisioning failures, member health issues, and TLS handshake errors.

Core Concepts

Concept	Description
Load Balancer	Top-level resource holding a virtual IP (VIP) on a chosen subnet

Member	A backend instance IP and port registered in a pool
Health Monitor	Periodic probes that mark members UP or DOWN
L7 Policy	HTTP routing rules — redirect, reject, or forward based on URL path or hostname
Flavor	Appliance capacity profile selected at provisioning time
