Infrastructure Built for Scale & Trust
A fully transparent look at the stack, infrastructure, and engineering practices that power CORPIUS — designed for enterprise reliability, military-grade security, and unlimited growth.
Architecture
Four-Tier System Design
Clean separation of concerns across presentation, edge, application, and data layers — following cloud-native best practices.
Client Layer
Vue 3 SPA rendered server-side via Inertia.js SSR for instant first paint and full SEO visibility.
Edge / Gateway
Nginx reverse proxy with TLS termination, FastCGI page caching, rate limiting, and static asset delivery.
Application Layer
Laravel 12 handles HTTP, business logic, authentication, job queuing, and Inertia.js page rendering.
Data Layer
PostgreSQL 15 for relational data, Redis for caching and queue, S3-compatible storage for files.
Components
Core Platform Services
Each service is independently deployable, purpose-built, and hardened for production — with no single points of failure.
Inertia.js SSR Server
Dedicated Node.js process that pre-renders Vue components on the server, returning full HTML on first request.
Laravel Application
Core business logic engine: routing, auth, payment processing, document generation, and REST API.
Vue 3 Frontend
Reactive SPA frontend built with Vue 3 Composition API, Tailwind CSS, and Headless UI.
PostgreSQL 15
Primary relational database for all user, order, document, and business entity records.
Redis Cache & Queue
In-memory data store used for session caching, rate limiting, and Laravel queue job dispatch.
Nginx Gateway
High-performance reverse proxy serving static assets, routing PHP, handling TLS, and FastCGI page caching.
Data Flow
Request Lifecycle
Every request follows a precisely engineered, secured pipeline — from DNS resolution to client-side hydration in under 200ms.
DNS Resolution & TLS Handshake
NetworkClient resolves corpius.net. Nginx terminates the TLS 1.3 connection, validates the certificate, and applies HSTS headers.
Nginx Routing & Cache Check
EdgeNginx inspects the URI. Static assets are served directly from disk. Dynamic PHP requests check the FastCGI cache — a HIT returns the cached HTML immediately.
PHP-FPM & Laravel Bootstrap
ApplicationOn a cache MISS, PHP-FPM receives the request. Laravel bootstraps the service container, resolves middleware (auth, CSRF, locale), and dispatches to the matched route.
Controller & Business Logic
LogicThe controller fetches data via Eloquent ORM (PostgreSQL), applies authorization policies, and passes the result as typed props to the Inertia response.
Inertia SSR Rendering
SSRThe SSR Node.js server receives the Inertia page payload, executes the Vue component tree, and returns fully-rendered HTML to Laravel for embedding in the Blade shell.
Response & Cache Write
ResponseNginx stores the rendered page in the FastCGI cache (for eligible public pages) and delivers the compressed HTML response to the client.
Client-side Hydration
ClientVue 3 hydrates the server-rendered DOM, enabling full SPA navigation for subsequent page visits — no additional full-page loads.
Infrastructure
Infrastructure & DevOps
Fully containerized, continuously deployed, and monitored 24/7 — zero manual steps required in the production delivery pipeline.
Containerization
- ◆ All services run as isolated Docker containers
- ◆ docker-compose orchestrates app, nginx, ssr, worker, database, redis
- ◆ Alpine-based images minimize attack surface and image size
- ◆ Volumes mount code and config at runtime — no baked secrets
Queue Workers
- ◆ Dedicated worker container running Laravel Horizon
- ◆ Processes email dispatch, document generation, and import jobs
- ◆ Retry logic with exponential back-off
- ◆ Failed jobs archived for manual inspection
SSL / TLS
- ◆ Let's Encrypt certificates with auto-renewal via Certbot
- ◆ TLS 1.2 / 1.3 only — older protocols disabled
- ◆ HSTS preloaded with max-age 1 year
- ◆ OCSP stapling enabled for fast certificate validation
Monitoring & Logging
- ◆ Laravel structured logging to storage/logs
- ◆ Nginx access and error logs per virtual host
- ◆ Microsoft Clarity for real-user behaviour analytics
- ◆ Yandex Metrica and Google Tag Manager for marketing analytics
Security
Multi-Layer Security
Security is not bolted on — it is engineered into every layer, from the network edge down to individual database fields.
TLS Encryption
All traffic is encrypted in transit via TLS 1.3. HTTP connections are permanently redirected to HTTPS.
CSRF Protection
Every state-changing request requires a valid CSRF token enforced by Laravel middleware.
Authentication
Laravel Sanctum provides session-based auth for the web app and token-based auth for API consumers.
Rate Limiting
Nginx and Laravel apply per-IP and per-endpoint rate limits to prevent brute-force and DDoS vectors.
Data Encryption
Sensitive fields are encrypted at rest using Laravel's AES-256-CBC encryption before database storage.
Input Sanitization
All user-supplied HTML is sanitized with DOMPurify client-side and HTML Purifier server-side.
CI / CD Pipeline
Automated Delivery
Every git push triggers a fully automated pipeline — tested, containerized, and deployed with zero manual intervention until the final production gate.
Test
test:phpPHPUnit / Pest test suite against a live PostgreSQL 15 service container. Runs migrations before each test run.
test:jsVite client + SSR build validation. Fails the pipeline if either bundle cannot be produced cleanly.
Build
build:dockerDocker image built with BuildKit layer caching using the previous :latest image. Tagged with commit SHA and :latest, then pushed to the GitLab Container Registry.
Deploy
deploy:stagingManual trigger on the develop branch. Rolls out new image to the staging namespace and runs artisan migrate + cache commands on the live pod.
deploy:productionManual trigger on main or a version tag. Updates all Kubernetes deployments in the corpius namespace with zero-downtime rolling update.
Orchestration
Kubernetes Infrastructure
All CORPIUS workloads run on Kubernetes — automatic horizontal scaling, self-healing, and zero-downtime rolling updates are built-in guarantees.
Deployments
- ◆ corpius-app — PHP-FPM (2–10 replicas, HPA)
- ◆ corpius-nginx — Nginx reverse proxy (2 replicas)
- ◆ corpius-ssr — Node.js SSR server (2–6 replicas, HPA)
- ◆ corpius-worker — Laravel queue worker (1–5 replicas, HPA)
Services
- ◆ ClusterIP for app:9000, ssr:13714, db:5432, redis:6379
- ◆ LoadBalancer for nginx:80/443 — external entry point
- ◆ Headless service for PostgreSQL StatefulSet
StatefulSets
- ◆ PostgreSQL 15 with persistent PVC (50 Gi)
- ◆ Redis with AOF persistence + PVC (10 Gi)
- ◆ Ordered pod startup ensures DB is ready before app
Ingress & TLS
- ◆ NGINX Ingress Controller with cert-manager
- ◆ Automatic TLS via Let's Encrypt ACME challenge
- ◆ corpius.net → corpius-nginx-service:443
ConfigMaps & Secrets
- ◆ ConfigMap for non-sensitive env vars (APP_URL, DB hosts…)
- ◆ Sealed Secrets / Vault for API keys, passwords, tokens
- ◆ Injected as env vars into all app containers
Horizontal Pod Autoscaler
- ◆ PHP-FPM scales 2→10 at 70% CPU
- ◆ SSR server scales 2→6 at 75% CPU
- ◆ Queue worker scales 1→5 based on Redis queue depth
Namespace Isolation
All workloads live in the corpius namespace. Staging runs in corpius-staging. Network policies enforce cross-namespace traffic restrictions, and GitLab CI's RBAC service account is scoped to only the resources it needs for deployment.

Every technology is selected for proven enterprise reliability, performance at scale, and long-term maintainability — not for trends.
