| Frontend |
Storefront + Reader UI + Admin portal UI |
Next.js (React) |
Strong SEO, fast page delivery, modern caching, great for multilingual & content discovery. |
| Backend |
APIs, commerce logic, entitlements, admin workflows |
NestJS (Node) or .NET |
NestJS = speed + hiring flexibility; .NET = enterprise governance. Both are proven in production. |
| Database |
Orders, payments, users, entitlements, catalog metadata |
PostgreSQL |
ACID transactions for commerce + mature tooling + reliable performance. |
| Caching |
Catalog cache, sessions, rate limit counters |
Redis |
Very fast cache reads; reduces DB load and improves latency for “hot” content. |
| Storage + CDN |
Covers, book files, static assets distribution |
Object storage + CDN |
CDN reduces latency; object storage is cost-effective for large files and scales easily. |
| Monitoring |
Logs, APM, tracing, alerting |
OpenTelemetry + APM (Sentry/Datadog/etc.) |
Standards-based tracing avoids observability vendor lock-in; faster incident response. |
| Security |
WAF, rate limiting, secrets, audit logs |
WAF + Secrets manager + RBAC |
Protects against common web threats, enforces least privilege, ensures auditable actions. |
