Cloud Cost Optimization: Reducing Infrastructure Spend by 42% via EKS Auto-Scaling

A high-growth B2B SaaS company was burning over $38,000 monthly on static EC2 instances with average CPU utilization hovering under 18%.

Kubernetes Modernization Strategy

We migrated their application microservices into an AWS EKS cluster orchestrated by Karpenter for rapid node provisioning and automated spot instance utilization.

Financial & Operational Results

• Monthly cloud infrastructure spend slashed from $38,000 to $22,000 (42% net reduction)
• Node provisioning latency dropped from 7 minutes to under 45 seconds during traffic spikes
• Implemented Prometheus and Grafana dashboards for granular cost-per-tenant attribution
• Zero application downtime recorded during the multi-week production migration

CTO Statement

“Antigravity’s cloud engineering team not only lowered our AWS bill permanently, but gave us a far more resilient infrastructure that effortlessly handles 10x our previous peak traffic.”
