About This Architecture

Nine-phase mobile order provisioning orchestration flows from Siebel order capture through REST microservices including Numeritrack number provisioning, Viper network setup, CUR customer record updates, Surepay payment configuration, INPROM inventory allocation, PEGA workflow tracking, and Oracle BRM billing activation. The TaaS orchestrator manages sequential phase execution with auto-retry logic (max 3 attempts, exponential backoff 1s/2s/4s) and compensating rollback transactions on failure, alerting via PEGA for exception handling. This architecture demonstrates enterprise service orchestration patterns for telecom operators managing complex multi-system order fulfillment with guaranteed consistency and audit trails. Fork this sequence diagram on Diagrams.so to customize retry policies, add new provisioning phases, or adapt the orchestration flow for your telecom stack.
