Scaling is not supported for services with persistent volumes.
You can run multiple instances of a web service, private service, or background worker to handle additional load. For services that receive incoming traffic, Render load balances that traffic evenly across all running instances: Portway supports two scaling methods: manual scaling and autoscaling.
MethodDescription
Manual ScalingManually set the number of instances for a service.
AutoscalingPortway automatically scale the number of instances for a service based on metrics.

​
Manual scaling

You can manually scale the number of instances for a service by updating the replicas field in the service definition. 
services:
  - name: my-service
    deploy: 
      replicas: 3
Deploy the updated compose file to apply the changes.
