Advanced payment orchestration implementation: microservices patterns, intelligent routing algorithms, performance optimization techniques, and production architecture for 10M+ transactions/month.

A Payment Orchestration Engine (POE) architecture  is a centralized and intelligent platform that serves as an intermediary layer between merchant applications and multiple payment service providers (PSPs), gateways, and acquirers. Its primary role is to simplify and optimize payment processing by managing all integrations through a single point of connection. The architecture uses rules-based logic  and dynamic routing  to direct transactions to the most suitable provider ba
