Overview

Quotas prevent individual projects from consuming excessive load balancing resources. Default quota values are set platform-wide; administrators override them per project. Load balancer quotas cover the full resource hierarchy — from the top-level load balancer down to individual L7 rules.
Administrator Access Required — This operation requires the admin role. Contact your Xloud administrator if you do not have sufficient permissions.

Default Quota Reference

​
View Quotas

Navigate to Admin → System → Defaults and scroll to the Load Balancer section to view platform-wide default quotas. Per-project overrides are visible in Admin → Identity → Projects → Modify Quotas.

​
Set Project Quotas

Navigate to Admin → Identity → Projects. Select the project and click Modify Quotas. Scroll to the Load Balancer section and update the limits.
Increase quotas for production projects that run multiple microservices behind separate load balancers. Keep development and test project quotas at defaults to control infrastructure costs.

​
Monitor Quota Consumption

Regularly review quota consumption to identify projects approaching limits:
List all project quotas sorted by load balancer count
openstack loadbalancer quota list --all-projects \
  -f json | python3 -c "
import json, sys
quotas = json.load(sys.stdin)
for q in sorted(quotas, key=lambda x: x.get('loadbalancer', 0), reverse=True)[:10]:
    print(f'{q.get(\"loadbalancer\",0):4d} LBs  {q[\"project_id\"]}')
"
