Architecture Overview
Linora is built on a modern, distributed architecture designed for high availability, low latency, and horizontal scalability. Our infrastructure spans multiple availability zones to ensure resilience against regional failures.
Core Components
API Gateway
All requests flow through our edge-deployed API gateway, which handles authentication, rate limiting, and request routing. The gateway operates at the edge for minimal latency regardless of user location.
Card Issuance Engine
The card issuance engine integrates with Visa and Mastercard networks through certified payment processors. Card data is tokenized at the point of generation and encrypted before delivery.
Exchange Engine
Our exchange engine aggregates liquidity from multiple sources to provide optimal rates across 500+ currency pairs. Transactions are matched and executed in real-time with automatic settlement.
Performance
- API Response Time -- p50: 45ms, p99: 180ms globally.
- Card Issuance -- Average delivery time under 30 seconds.
- Exchange Execution -- Typical processing time of 5-30 minutes depending on network confirmation times.
- Availability -- 99.9% uptime SLA with automatic failover.
Technology Stack
- Frontend -- Next.js with React, deployed on Vercel's edge network.
- API Layer -- Node.js with TypeScript, serverless functions for scalability.
- Encryption -- TLS 1.3, AES-256-GCM at rest, with HSM-managed keys.
- Monitoring -- Real-time observability across all service layers.
Scalability
Linora's serverless architecture scales automatically with demand. There are no fixed infrastructure limits -- the system provisions resources dynamically based on traffic patterns. This ensures consistent performance during peak periods without over-provisioning during quiet times.
