Self-hosted API gateway TCO

The true cost of free. EKS node cost + observability stack + ops FTE fraction, compared to the managed SaaS equivalent.

// Self-hosted TCO model monthly
{
"eks_control_plane": "$73.00", // 0.10/hr × 730 hr/mo
"eks_worker_nodes": "$200.00", // 3 × m5.large on-demand
"observability_stack": "$350.00", // Grafana Cloud or self-host equivalent
"log_shipping_egress": "$80.00", // 5 GB/M calls × 0.09/GB
"ops_fte_at_0_50": "$7,292.00", // 0.5 × loaded $175k/yr
"total_monthly": "$7,995.00" // before SLA penalty / on-call overhead
}

Break-even versus managed

Compare the figure above to Kong Konnect Plus at $250/month for 5 services , or Tyk Cloud at the low-hundreds-per-month entry tier . The managed SaaS markup is paid for by the ops FTE you do not hire. The break-even point is sensitive to the FTE fraction you assume and to whether you already have a Kubernetes platform team paying the EKS bill anyway.
