I'm looking for a discussion on the clear signs that indicate it's time to transition to Kubernetes. General answers like 'when you need scaling' aren't helpful—what specific symptoms or situations would suggest that Kubernetes is the right solution?

For me, it's when developers need self-service capabilities. With a well-structured Kubernetes cluster, they can quickly deploy services without bottlenecks, streamlining operations—although it's essential to manage expectations regarding their ability to handle complex infrastructure.
One significant symptom is if your on-call team is constantly scrambling to create, remove, or restart container instances. Kubernetes automates those tasks, allowing you to focus on more critical issues.
If you're managing around eight Docker containers spread across different hosts with unique scaling needs, and you want everything to remain operational after reboots without manually configuring each host, Kubernetes could be your solution.
We made the jump to Kubernetes when we were juggling a dozen ECS clusters, each with 50 to 200 containers. We realized it would be easier to scale with Kubernetes rather than tackle our overwhelming Terraform configurations.
