The Honest Answer
Most startups don't need Kubernetes. There, we said it. But the startups that do need it — need it badly. Here's how to know which camp you're in.
Signs You're NOT Ready for Kubernetes
You have fewer than 5 services. You have no dedicated DevOps engineer. Your team hasn't mastered Docker yet. You're pre-product-market fit. In all these cases, Kubernetes will slow you down more than it speeds you up.
Better alternatives: Railway, Render, or AWS App Runner give you container orchestration without the operational complexity. ECS Fargate is a reasonable middle ground — managed containers without K8s complexity.
Signs You ARE Ready
You're running 8+ microservices with different scaling requirements. You have clear traffic patterns requiring auto-scaling. You need multi-region deployment. You have dedicated platform/infrastructure engineers. You're spending >$5k/month on EC2 instances that could be bin-packed more efficiently.
The Migration Checklist We Use
Before recommending K8s to any client, we verify: all services are containerized, the team understands Docker networking, you have a CI/CD pipeline, you have observability (logs, metrics, traces), and you have a clear cost justification.
The EKS Path for AWS Users
EKS (Elastic Kubernetes Service) removes cluster control plane management. Combined with Fargate profiles for serverless node management, you can run a serious K8s setup with a 2-person platform team.
The Real Cost
Factor in: engineer time to manage the cluster (20-40hrs/month), tooling (Lens, Datadog, etc.), and the cognitive overhead on your development team. Kubernetes pays off at scale. Before that scale, it's expensive complexity.
