Terraform vs Kubernetes: You Need Both, in Sequence
Terraform and Kubernetes are not competitors. Terraform provisions the cluster; Kubernetes runs the workloads inside it. With Terraform 1.16.5 and Kubernetes 1.37.1 current, here is exactly where the boundary sits in 2026 — and where the Terraform Kubernetes provider stops working.
Tenable vs Qualys: Which One to Pick in 2026
