Episode notes
Scaling Audio Call WebSockets
- A call-based app spun up 4 containers per WebSocket call inside Kubernetes pods.
- Scaling to thousands of calls required rethinking container and pod management.
Use EKS and Karpenter for Scaling
- Use managed Kubernetes services like Amazon EKS to ease the infrastructure burden.
- Use tools like Karpenter to autoscale nodes efficiently based on workload demand.
Kubernetes Enables Automated CI/CD
- Kubernetes' API and control plane enable automated CI/CD pipelines.
- This allows zero downtime deployments and controlled rollbacks in production.
