Nomad vs. Kubernetes: Why We Switched Our SaaS to HashiCorp Nomad

The Complexity Tax: Why Kubernetes Isn't Always the Answer In the modern DevOps landscape, Kubernetes (K8s) is often treated as the default choice for container orchestration. It's powerful, battle-tested, and has a massive ecosystem. However, for many small-to-medium SaaS teams, Kubernetes comes with a significant "complexity tax." We spent two years managing a production K8s cluster. While it solved our scaling issues, we found ourselves spending 30% of our engineering time just maintaining the orchestrator itself—debugging CNI plugins, managing complex RBAC, and wrestling with Helm charts that felt like they required a PhD to understand. That's when we looked at HashiCorp Nomad. Nomad is a lightweight, flexible orchestrator that can manage both containerized and non-containerized applications. It follows the Unix philosophy: do one thing and do it well. In this article, I’ll walk you through why we made the switch, the architectural differences, and how you can implement a productio
