Description
Ensuring high availability of EPICS network services is increasingly important as control systems scale. By combining VRRP to provide IP‑layer mobility with Round‑Robin DNS for lightweight distribution, it is possible to build resilient configurations that tolerate client-side and server-side failures.
These techniques are commonly used for services such as load balancing provided by HAProxy and can be applied directly to PVAGateway and other services, enabling seamless failover, reduced downtime during updates, and improved robustness without requiring changes to EPICS clients. This approach offers a practical method for enhancing service availability while maintaining operational simplicity.
