SaaS Technical Architecture
How we build secure, high-performance, and scalable cloud platforms
Frontend Layer
Next.js SSR / React SPA / React Native App
API Layer
Next.js API Routes / Edge Functions / REST
Application Services
Auth / Real-time Push / File Storage / Scheduled Tasks
Data Layer
PostgreSQL + RLS Data Isolation / Redis Cache
Infrastructure Layer
Vercel Edge Network / Docker / CI/CD Automation
IoT / Hardware Layer
Smart Meters / Face Recognition Devices / MQTT Gateway
Multi-Tenant Isolation
PostgreSQL RLS ensures complete data isolation between tenants, preventing any cross-organization data leakage.
Horizontal Scaling
Stateless architecture with Edge Network CDN global nodes handles traffic spikes effortlessly.
End-to-End Security
HTTPS encryption, JWT authentication, API key management — military-grade data protection.
Our Development Process
Infowin Hybrid Vault
Business logic updates in the cloud; the database is deployed in your on-premises server room. Solve the 'data anxiety' of the SaaS era while maintaining both agility and sovereignty.
Architecture Overview
☁️ Cloud Logic Layer
UI / Business Logic / AI Algorithms — continuously auto-updated
🔒 System Command Flow (mTLS)
Mutual TLS encrypted tunnel — computation commands only, raw data never leaves
🌐 Personnel Access Flow (Cloudflare)
Zero Trust Tunnel — secure remote access for authorized staff (Elite)
🏠 Local Data Layer
PostgreSQL / Redis — deployed in your server room, IP never exposed
Three Security Pillars
Row-Level Security (RLS)
Even in the cloud, PostgreSQL RLS ensures absolute isolation between tenants — engineers cannot cross-read data.
Complete Audit Trail (Audit Log)
Every read, modification, and deletion is recorded with tamper-proof logs: who, when, what.
One-Click Local Deployment
Deploy local database with one Docker command. Schema auto-migrates — no manual maintenance needed.
Technical Specifications
Transport Encryption
AES-256 GCM TLS 1.3
Data Isolation
PostgreSQL RLS
Deployment
Docker One-click install script
Protocol
gRPC / REST over mTLS
Ideal for: Law firms, CPA firms, temple trusts, high-net-worth asset management
