Overprovisioned Kubernetes Nodes & Slow Auto-Scaling Bottlenecks
Kubernetes Karpenter Autoscaling & Compute Cost Fix
Fix slow pod provisioning and cut Kubernetes cloud costs. We replace legacy Cluster Autoscalers with Karpenter, adopt discounted spot instances, and tune pod limits.
Diagnostic Symptoms
Indicators That Your Platform Has This Bottleneck
Common performance, cost, and reliability warning signs that require immediate engineering remediation.
Nodes Taking 5+ Minutes to Boot Under Traffic
Legacy EC2 Auto Scaling Groups causing pending pods to wait minutes during sudden traffic surges.
Paying for Massive Overprovisioned Idle Nodes
Running expensive on-demand instances 24/7 with low average CPU utilization.
OOMKill Outages from Untuned Resource Limits
Pods crashing unpredictably because of missing or misconfigured memory requests and limits.

Questions About This Remediation
How does Karpenter provision nodes faster than Cluster Autoscaler?
Cluster Autoscaler interacts with slow AWS Auto Scaling Groups. Karpenter bypasses ASGs and directly launches exact-fit EC2 instances via fleet APIs.
What happens when AWS reclaims a spot instance?
Karpenter receives the 2-minute AWS termination notice, cordons and drains the node, and provisions a replacement instance before termination.
