I'm starting a new SaaS project and everyone keeps telling me to use Kubernetes (K8s) for orchestration. However, the operational complexity seems overkill for a small team of three. Is it better to stick with simpler alternatives like AWS ECS or Docker Swarm, or will I regret not having the scalability of K8s later on when we hit 10k users?

The "Kubernetes Tax" is real. For a small team, the overhead of managing ETCD, networking, and security policies can distract you from building your actual product. In 2024, I would suggest starting with AWS App Runner or ECS Fargate. These "Serverless" container options allow you to scale horizontally without managing the underlying cluster nodes. You can always migrate to EKS (Elastic Kubernetes Service) later using a "BFF" (Backend for Frontend) pattern once your complexity warrants the control that Kubernetes provides.
What specific features of Kubernetes are you attracted to? Is it the self-healing capabilities, or are you looking for a vendor-agnostic way to deploy your microservices across different cloud providers?
If you want the best of both worlds, try a managed K8s service with "Autopilot" mode. It removes the management headache while giving you access to the Kubernetes API.
I agree with Thomas. GKE Autopilot is a fantastic middle ground. It lets you focus on your manifests while Google handles the cluster health and scaling.
Joseph, my main interest is the ecosystem—Helm charts and Prometheus operators make monitoring and third-party integrations so much easier. I'm just worried that I'll spend all my time debugging YAML files instead of shipping features. If ECS can provide a similar "one-click" experience for things like Redis or Postgres, I'd definitely prefer that for the first six months.
