BAB 54. DEPLOYMENT ARCHITECTURE

Tujuan

Deployment dirancang agar mudah dimulai dari satu sekolah namun siap berkembang menjadi multi-school nasional tanpa perubahan arsitektur mendasar.

Lingkungan Deployment

Environment	Fungsi	Akses
Local	Development dan debugging	Developer
Staging	Testing sebelum production	Tim QA + Stakeholder
Production	Operasional nyata	Pengguna akhir

Skalabilitas Bertahap

Tahap 1 — Satu Sekolah (Awal)

1 VM (4 vCPU, 8GB RAM)
├── Nginx
├── Laravel (PHP-FPM)
├── MySQL
├── Redis
├── Queue Worker (1 instance)
└── Reverb WebSocket

Tahap 2 — Multi Sekolah (Berkembang)

Load Balancer
├── App Server 1 (Laravel)
├── App Server 2 (Laravel)
├── App Server 3 (Laravel)
├── MySQL Primary + Read Replica
├── Redis Cluster
└── Queue Worker (Multiple)

Tahap 3 — Nasional (Scale)

    listen 443 ssl http2;
    server_name api.temubelajar.id;

    ssl_certificate /etc/ssl/temubelajar.crt;
    ssl_certificate_key /etc/ssl/temubelajar.key;

    root /var/www/temubelajar/public;
    index index.php;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php/php8.4-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
