Your quota issue requires both immediate action and long-term resource optimization. Here’s the comprehensive approach:
1. Resource Quota Management:
First, get complete visibility into quota usage:
ibmcloud resource quotas
ibmcloud is instances --output json | \
jq 'group_by(.zone)[] | {zone: .[0].zone, count: length}'
This shows instance distribution across zones. Request quota increase to 100 instances (double your current need) to allow future growth. In your quota request, justify based on IoT gateway expansion plan and mention production workload requirements.
2. Edge VM Provisioning Optimization:
Before provisioning new instances, audit existing resources:
ibmcloud is instances --output json | \
jq '.[] | select(.status=="stopped" or .status=="failed")'
Delete stopped or failed instances to free quota:
ibmcloud is instance-delete <instance-id> --force
For new gateway deployments, use placement groups to ensure proper distribution and resource allocation.
3. IBM Cloud CLI Monitoring:
Set up automated quota monitoring:
#!/bin/bash
CURRENT=$(ibmcloud is instances --output json | jq 'length')
LIMIT=$(ibmcloud resource quotas | grep instances | awk '{print $3}')
USAGE=$((100 * CURRENT / LIMIT))
if [ $USAGE -gt 80 ]; then
echo "Warning: Instance quota at ${USAGE}%"
# Send alert to monitoring system
fi
Run this daily via cron or integrate into your CI/CD pipeline.
Immediate Actions:
- Submit quota increase request for 100 instances (provide business justification)
- Audit and delete unused instances (check for test/dev instances no longer needed)
- Identify stopped instances consuming quota slots
- Clean up failed provisioning attempts
Long-term Strategy:
- Implement instance tagging for better resource tracking (gateway-prod, gateway-dev)
- Use instance templates for consistent gateway deployment
- Set up resource groups per region for clearer quota allocation
- Consider reserved capacity for production gateways
- Implement automated cleanup policies for temporary instances
Gateway Deployment Best Practices:
- Use instance profiles optimized for IoT workloads (cx2 family for compute-intensive gateways)
- Deploy in availability zones strategically based on device distribution
- Implement health checks and auto-recovery for gateway instances
- Use security groups specific to IoT gateway traffic patterns
The quota increase should process within 1-2 business days. Meanwhile, cleaning up unused resources might free enough quota for partial deployment. For the remaining gateways, wait for quota approval before provisioning to avoid failed attempts that consume quota temporarily.
