Insight: From Chaos to Control Plane—Is EKS Really That Much Easier Than On-Prem Kubernetes?
When I came across a post from an SRE managing an on-prem Kubernetes cluster on RHEL, it struck a chord. Every day brought a new issue: master nodes dropping off, worker nodes becoming unreachable, and endless layers of network and VM complexity to peel back. Anyone who’s operated Kubernetes on bare metal or traditional virtualization knows the drill — it’s a daily dance with entropy, and your only partner is kubectl and hope.
This is the reality for many engineers who still manage clusters in datacenters or hybrid clouds. You patch VMs, babysit control planes, troubleshoot disk I/O issues, and triage hardware blips — all while keeping containerized workloads running smoothly. It's the ultimate full-stack challenge: networking, storage, CPU scheduling, and orchestration all wrapped into one. If you love complexity, it’s a paradise. If you’re trying to ship features? It's a drag.
The EKS Shift: AWS Takes the Keys to the Control Plane
Enter Amazon EKS. The promise is simple: you no longer manage the Kubernetes control plane — AWS does. No more spinning up kubeadm, manually building clusters, or scrambling when your etcd cluster starts throwing errors at 3 a.m. In EKS, the masters are invisible. You can't SSH into them because they don’t belong to you. And that’s the idea. AWS handles high availability, backups, and upgrades behind the scenes. You get an API endpoint and a functioning cluster — without worrying about the scaffolding beneath it.
This shift isn’t just about convenience. It’s a reorientation of responsibility. You still manage the worker nodes, yes — but even that can be delegated to Fargate profiles or managed node groups if you prefer. Suddenly, your job isn't about keeping the cluster alive. It’s about making the workloads behave. It’s a different kind of challenge — and one that’s arguably closer to the heart of DevOps.
The New Complexity: It Doesn’t Disappear — It Relocates
But let’s be clear. EKS doesn’t make Kubernetes simple. It makes it different. You still have to design for availability zones. You still troubleshoot networking issues — only now they’re related to VPC-CNI plugins, security groups, or subnet exhaustion. IAM permissions can break your deployments in opaque ways. And when autoscaling fails, it’s not a broken daemonset — it’s an upstream config, or a misaligned CloudWatch metric, or an EC2 quota buried in a different AWS region.
Control plane issues are now rare — but dependency issues, integration pain, and AWS service drift can still eat your week. What used to be journalctl and rebooting nodes becomes digging through CloudFormation templates or reconciling eksctl state with reality. It’s less greasy, but just as complex.
So Is EKS Worth It? Without a Doubt — But Eyes Open
For most teams, EKS is absolutely worth it. You lose a lot of the duct tape and danger that come with running Kubernetes by hand. AWS scales the infrastructure so you don’t have to — and that’s no small thing. But it doesn’t scale your logic. The hard thinking, the architectural decisions, and the day-two pain? That’s still on you.
So before migrating to EKS, ask yourself: do you want to stop fixing broken nodes — only to start debugging IAM roles and VPC layouts instead? If so, welcome aboard. EKS won’t make Kubernetes disappear. But it will make the chaos more manageable — and that might be the best deal you get all week.
