Sample Architecture Document

Anonymized infrastructure design from a recent B2B platform build.

While AI agents rapidly generate boilerplate and individual module code, our Senior Human Engineers are strictly responsible for system architecture and security protocols. Here is a high-level summary of a standard modern stack we deploy.

1. High-Level Stack

  • Frontend: React (Next.js) with TypeScript. Tailored for fast SSR/SSG page loads and highly interactive dashboards.
  • Backend: Node.js (Express or NestJS) providing a strict REST or GraphQL API layer.
  • Data Store: PostgreSQL (relational master) and Redis (in-memory caching & session management).

2. Infrastructure & Cloud Setup (AWS Example)

Deployments are fully containerized using Docker and orchestrated to scale under load:

  • Compute: Amazon Elastic Kubernetes Service (EKS) or ECS for container management with auto-scaling groups based on CPU/RAM thresholds.
  • Database: Amazon RDS for PostgreSQL with Multi-AZ deployments for redundancy and point-in-time recovery.
  • CDN & WAF: Cloudflare or AWS CloudFront for edge caching, DDoS protection, and SSL offloading.

3. Security Architecture

Security is baked into the foundation to meet complex compliance requirements:

  • Encryption: AES-256 for all stored data at rest (database volumes and S3 document buckets). TLS 1.3 enforced for all in-transit communications.
  • Authentication: OAuth2 / OIDC compliant JWT-based authentication combined with strict Role-Based Access Control (RBAC).
  • Observability: Centralized immutable audit logs aggregating via Elasticsearch (ELK Stack) or Datadog for rapid incident response.
