EV Charging Network: Multi-Region Architecture

Mission Briefing

EV charging backends need low-latency global availability. OCPP chargers → API Gateway → Lambda → DynamoDB Global Tables for multi-region session state, with Global Accelerator routing, CloudWatch charger health, and weekly carbon-avoided reports via Athena.
