# Slashing Kubernetes Cloud Bills by 45%
Cloud spending in Kubernetes clusters often spirals due to over-provisioned CPU and memory requests. Here are 4 engineering practices Innovtec implements for enterprise clients:
## 1. Karpenter for Intelligent Node Provisioning
Replace generic Cluster Autoscaler with Karpenter on AWS to launch exact-sized EC2 instances within seconds based on pod resource requirements.
## 2. Spot Instance Mixed Node Groups
Utilize spot instances for stateless worker workloads with automated fallback to on-demand instances upon termination notices.
## 3. Horizontal & Vertical Pod Autoscaling
Combine HPA (traffic driven) and VPA (historical usage recommendation) to ensure pods scale efficiently without wasting idle memory.
