Benefits of the New IMS Deployment

The deployment represents New Zealand’s first IMS node operational on Red Hat OpenStack Platform, streamlining Spark’s network from multiple bespoke systems to a single, efficient solution. This change is expected to reduce operational costs, lower latency, and improve overall service reliability.

By the end of the year, Spark plans to migrate its existing IMS nodes to this unified platform, which will enable any single node to handle the entire country’s traffic load. This setup ensures uninterrupted service even if some nodes encounter issues, the official release said.

Spark said the South Island IMS deployment was the first in New Zealand to go live and be fully operational with Red Hat OpenStack Platform. It represents a shift from multiple bespoke stacks to a singular, cost-effective solution.
