Production Hardening

This reference document provides guidelines for operating Ella Core in a production environment.

Recommendations

  • Deploy on a production-grade system. Ensure your system meets the production requirements.
  • Deploy with the snap: Use the Snap installation method to deploy Ella Core.
  • Isolate network interfaces: Use separate network interfaces for N2, N3, N6, and API traffic.
  • Use TLS: Configure TLS for the API interface in the configuration file. Use certificates from a trusted Certificate Authority (CA).
  • Use XDP in native mode: Configure Ella Core to use XDP in native mode. This requires a compatible network driver.
  • Set logging level to info: Configure system logging level to info and use file output.
  • Disable telemetry: Disable telemetry in the configuration file.
  • Rotate logs: Implement log rotation for system and audit logs.
  • Back up the database: Back up the database file on a daily basis. Retain backups for at least 7 days.
  • Monitor metrics: Operate an external Observability stack to collect and visualize metrics exposed by Ella Core.
