Configuring Auto-Scaling Policies
Overview
Configure auto-scaling policies for cloud workloads across AWS Auto Scaling Groups, GCP Managed Instance Groups, Azure VMSS, and Kubernetes Horizontal Pod Autoscaler (HPA). Generate scaling configurations based on CPU, memory, request rate, or custom metrics with appropriate thresholds, cooldown periods, and scale-in protection.
Prerequisites
- Cloud provider CLI installed and authenticated (
aws, gcloud, or az)
- For Kubernetes HPA:
kubectl configured with cluster access and metrics-server deployed
- Baseline performance data for the target workload (average CPU, memory, request rate)
- Understanding of traffic patterns (steady, bursty, scheduled)
- IAM permissions to create/modify scaling policies and CloudWatch/Stackdriver alarms
Instructions
- Identify the scaling target: EC2 Auto Scaling Group, GCP MIG, Azure VMSS, or Kubernetes Deployment
- Analyze current workload metrics to establish baseline utilization and peak patterns
- Define scaling boundaries: minimum instances/pods, maximum instances/pods, desired count
- Select scaling metric(s): CPU utilization, memory, request count, queue depth, or custom metrics
- Set target thresholds: scale-out trigger (e.g., CPU > 70%), scale-in trigger (e.g., CPU < 30%)
- Configure cooldown periods to prevent flapping (typically 300s scale-out, 600s scale-in)
- Add scale-in protection for stateful workloads or leader nodes if needed
- Generate the scaling policy configuration in the appropriate format (Terraform, YAML, or CLI commands)
- Validate by simulating load and confirming scaling events fire correctly
Output
- Terraform HCL for AWS ASG scaling policies with CloudWatch alarms
- Kubernetes HPA manifests (YAML) with resource or custom metric targets
- GCP autoscaler configurations for Managed Instance Groups
- Scaling policy JSON/YAML for Azure VMSS
- CloudWatch or Stackdriver alarm definitions tied to scaling actions
Error Handling
| Error | Cause | Solution |
|---|
No scaling activity despite high load | Metric not reaching threshold or cooldown active | Verify metric source in CloudWatch/Stackdriver; check cooldown timer with describe-scaling-activities |
