Key summary
A lead engineer shares the architecture of Elites Africa, a bill payment platform that handles user funds and crypto payments. The platform uses a Multi-Provider Failover strategy to ensure high availability and reliability, and an Internal Abstraction Layer to handle incompatible provider metadata.
TL;DR
- Elites Africa uses a Multi-Provider Failover strategy for high availability and reliability.
- The platform has a primary provider with a 'hot' secondary backup for real-time recovery.
- An Internal Abstraction Layer handles incompatible provider metadata.
- The system uses a standardized internal schema to represent logical services.
- A weekly synchronization script maps provider metadata to internal codes.
- The platform assumes providers will fail and has a plan for when they do.
- True architectural maturity is about how gracefully a system fails.
