# Clustering and scaling

PingAuthorize Servers are stateless. They do not require intra-cluster communication to scale. Instead, similarly configured independent server instances can be added behind the same network load balancer to achieve higher throughput while maintaining low latency.

## Automated environments

To maintain identically configured PingAuthorize Server instances behind your load balancer, use DevOps principles of Infrastructure-as-Code (IaC) and Automation. For more information about using server profiles to scale upward by installing a new, identically configured instance of PingAuthorize Server, see [Deployment automation and server profiles](../pingauthorize_server_administration_guide/paz_deploy_auto_server_prof.html).
