Do I need Kubernetes to handle node failures automatically?

Not necessarily.

You do not need Kubernetes just to handle node failures automatically, but Kubernetes is one of the most common tools for doing it in containerized environments.

If you want automatic recovery from node failure, you have a few options:

• Kubernetes: automatically reschedules containers/pods onto healthy nodes if a node dies.
• Cloud-managed services: e.g. AWS Auto Scaling Groups, GCP Managed Instance Groups, Azure VM Scale Sets can replace failed VMs automatically.
• Other orchestration platforms: Nomad, Docker Swarm, ECS, etc.
• Application-level redundancy: running multiple instances behind a load balancer and using health checks.

Key idea

If a node fails, you need:

1. A scheduler or orchestrator to detect failure and place workloads elsewhere.
2. Multiple nodes so there’s somewhere to move workloads.
3. Health checks / monitoring to notice the failure quickly.
4. Fault-tolerant app design so the app can survive restarts or failover.

When Kubernetes makes sense

Use Kubernetes if you want:

• automatic rescheduling
• self-healing
• service discovery
• rolling updates
• scaling across many nodes

When you may not need it

You might not need Kubernetes if:

• your app is small
• you only have a few services
• you can use a simpler platform or managed service
• you just need VM replacement, not container orchestration

If you want, I can also compare Kubernetes vs Auto Scaling Groups vs ECS/Nomad for node-failure handling.
