We currently run our app on simple Docker containers. At what point does the complexity of managing these manually become too much, and we need to transition to a DevOps orchestration platform like Kubernetes?

You need Kubernetes the moment you have more than a handful of containers and need features like "self-healing" or "auto-scaling." If a Docker container crashes on a single VM, it stays down. Kubernetes detects the failure and automatically restarts the pod on a healthy node. It also handles service discovery and load balancing internally. In the DevOps world, K8s allows you to treat your infrastructure as a fleet rather than individual servers, which is essential once your traffic starts fluctuating or your service count grows.
Is the steep learning curve of Kubernetes worth it for a small startup, or should we look at managed services like AWS ECS or Google Cloud Run first?
Managed Kubernetes services like EKS or GKE are a great middle ground. They handle the control plane maintenance, so your DevOps team can focus on the worker nodes and applications.
I totally agree, Martha. Using EKS takes away about 50% of the headache associated with running Kubernetes while keeping all the orchestration power.
For a startup, ECS or Cloud Run is often better, Louis. They provide many DevOps benefits without the "operational tax" of managing a full Kubernetes cluster. Once you need complex networking, custom CRDs, or multi-cloud portability, then the investment in learning and migrating to Kubernetes becomes much more justifiable for the business.
