Kubernetes orchestrates container deployment, scaling, and management. The industry standard for production container workloads. Powerful but complex.
Reviewer scorecard
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“The standard for production container orchestration. Managed K8s (EKS, GKE, AKS) removes most operational burden.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“Massively over-engineered for 90% of workloads. Most teams would be better served by simpler deployment platforms.”
“Fly.io is the answer for workloads that don't fit the serverless model. As AI inference goes local-first, having servers in 30+ regions matters.”
“The API model Kubernetes established is becoming the universal infrastructure abstraction layer.”
