Continuous Application Availability for Cellular Network

Situation

A cellular provider services a large and growing population of cell phone customers. All traffic for a given subscriber is routed to only one system at a time.

Problem

The provider needed to improve cell phone services and provisioning to be more efficiently load-balanced and continuously available to avoid data collisions when running in an active/active business continuity architecture. This problem required improvements in network routing capabilities and system scale-out as well as redundancy to survive any catastrophic system, datacenter, or regional disaster.


Solution

  • Use HPE Shadowbase bi-directional data replication to synchronize application databases in a “route anywhere” model (any user/transaction can be serviced by any system)
  • Apply relative replication to correct data collisions, keeping records consistent across nodes
